Maven搭建SpringMVC+Hibernate项目详解



前言

     今天复习一下SpringMVC+Hibernate的搭建，本来想着将Spring-Security权限控制框架也映入其中的，但是发现内容太多了，Spring-Security的就留在下一篇吧，这篇主要搭建SpringMVC4.1.4和Hibernate4.3.8，之前也打了好多SpringMVC的，这部分已经非常的熟悉了，毕竟业开发过一年多SpringMVC的，这次持久层采用Hibernate，数据源采用c3p0，数据库暂采用MySQL，主要是想复习一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下：

     1、设计数据库：设计好表结构，最好符合3NF，采用Hibernate tools将设计好的表自动生成对应的实体entity。

     1、创建Maven项目，按需映入Maven包依赖。

     2、搭建Spring：配置Spring对控件层Bean的注入。

     3、搭建Hibernate：配置数据源，配置SessionFactory，配置事务，以及二级缓存ehcache的配置。

     4、测试Spring+Hibernate的框架搭建，写单元测试JUnit，测试事务配置等。

     5、映入SpringMVC：配置SpringMVC配置信息。

     6、配置web.xml容器

     7、测试三个框架的整合：Maven编译打包部署服务器，测试。

1、数据库设计

       设计一个权限、角色、用户的表。自然如果一个用户可以有多个角色，一个角色多个用户所拥有；一个角色拥有多个权限，一个权限对应多个角色。所以按照数据库表结构设计，符合3NF的话我们需要5张表进行存在。表的具体信息就不列出了（可以下在源码，里面还有数据库），表关系如下：

      

      这里面ID才用到是java的UUID（36位）

2、创建Maven项目，编写pom.xml文件

      创建一个Maven的webapp项目，编写pom.xml文件，引入所需的包依赖，我这里就将所需的全部的映入了。

       

      pom.xml文件内容如下:

       

  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

3、引入Spring配置

    编写配置文件，配置文件放在src/main/resources资源目录下（下同）。

   项目所需的配置信息config.properties

  

#application configs#jdbc c3p0 configjdbc.driver = com.mysql.jdbc.Driverjdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8jdbc.username = rootjdbc.password = 12345#hibernate confighibernate.dialect = org.hibernate.dialect.MySQLDialecthibernate.show_sql = truehibernate.format_sql = falsehibernate.hbm2ddl.auto = updatehibernate.cache.use_second_level_cache = truehibernate.cache.use_query_cache = truehibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactoryhibernate.cache.provider_configuration_file_resource_path = ehcache.xml

3.1、spring配置

spring.xml的配置文件如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.1.xsd"><!-- 加载配置文件 --><context:property-placeholder location="classpath:config.properties"/><!-- 扫描service自动注入为bean --><context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" /></beans>

上面spring配置了对应包下组件bean自动注入管理，我们需要将dao,service的实现类交由spring管理，如（@Repository，@Service）。

3.2、引入日志文件配置Log4j

  log4j.properties的配置文件如下：

 

### set log levels ###log4j.rootLogger = INFO , C , D , E ### console ###log4j.appender.C = org.apache.log4j.ConsoleAppenderlog4j.appender.C.Target = System.outlog4j.appender.C.layout = org.apache.log4j.PatternLayoutlog4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n### log file ###log4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.File = ../logs/springmvc_hibernate_demo.loglog4j.appender.D.Append = truelog4j.appender.D.Threshold = INFO log4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n### exception ###log4j.appender.E = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log log4j.appender.E.Append = truelog4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayoutlog4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

4、Hibernate配置

      Hibernate的配置主要包括：配置数据源c3p0，配置SessionFactory，配置事务管理器，配置事务管理，其spring-hibernate.xml文件如下：

     

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"><!-- 配置数据源 c3p0 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"destroy-method="close"><property name="driverClass" value="${jdbc.driver}" /><property name="jdbcUrl" value="${jdbc.url}" /><property name="user" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /><!-- 请求超时时间 --><property name="checkoutTimeout" value="30000" /><!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 --><property name="idleConnectionTestPeriod" value="30" /><!-- 连接数据库连接池最大空闲时间 --><property name="maxIdleTime" value="30" /><!-- 连接池初始化连接数 --><property name="initialPoolSize" value="5" /><property name="minPoolSize" value="5" /><property name="maxPoolSize" value="20" /><!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 --><property name="acquireIncrement" value="5" /></bean><!-- 配置hibernate的SessionFactory --><bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><!-- 注入数据源 相关信息看源码 --><property name="dataSource" ref="dataSource" /><!-- hibernate配置信息 --><property name="hibernateProperties"><props><prop key="hibernate.dialect">${hibernate.dialect}</prop><prop key="hibernate.show_sql">${hibernate.show_sql}</prop><prop key="hibernate.format_sql">${hibernate.format_sql}</prop><prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop><!-- 开启二级缓存 ehcache --><prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop><prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop><prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop><prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path}</prop></props></property><!-- 扫描hibernate注解配置的entity --><property name="packagesToScan" value="org.andy.work.entity" /></bean><!-- 配置事务管理器 --><bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean><!-- 配置事务增强处理Bean，指定事务管理器 --><tx:advice id="transactionAdvice" transaction-manager="transactionManager"><!-- 配置详细事务处理语义 --><tx:attributes><tx:method name="insert*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /><tx:method name="get*" propagation="SUPPORTS" read-only="true" /><tx:method name="find*" propagation="SUPPORTS" read-only="true" /><tx:method name="select*" propagation="SUPPORTS" read-only="true" /><tx:method name="load*" propagation="SUPPORTS" read-only="true" /><!-- 其他采用默认事务方式 --><tx:method name="*" /></tx:attributes></tx:advice><!-- Spring aop事务管理 --><aop:config><!-- 配置切入点 --><aop:pointcut id="transactionPointcut"expression="execution(* org.andy.work.service..*Impl.*(..))" /><!-- 指定在txAdvice切入点应用txAdvice事务增强处理 --><aop:advisor pointcut-ref="transactionPointcut"advice-ref="transactionAdvice" /></aop:config></beans>

     上面配置了二级缓存，ehcache，相关的具体信息查看上一篇Hibernate二级缓存以及ehcache的搭建配置，下面是二级缓存的配置。

4.1、ehcache.xml的配置

       

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd"><diskStore path="D:/ehcache" /><!-- DefaultCache setting. -->     <defaultCache            maxElementsInMemory="1000"            eternal="false"            timeToIdleSeconds="120"            timeToLiveSeconds="120"            maxElementsOnDisk="1000000"            overflowToDisk="true"             memoryStoreEvictionPolicy="LRU">                </defaultCache><!-- Special objects setting. --><cache      name="org.andy.work.entity.AcctUser" maxElementsInMemory="2" memoryStoreEvictionPolicy="LRU"  eternal="true"  diskPersistent="false" overflowToDisk="false"  maxElementsOnDisk="1000000" /> </ehcache>

   上面Hibernate二级缓存ehcache存放磁盘是D:/ehcache

5、生成业务entity实体

      设计好数据表后，Hibernate的实体有工具Hibernate tools自动生成，Eclipse需要安装Hibernate tools插件（我在线安装过几次都不成功，推荐使用links离线安装，附录将介绍），所以不需要手工的书写，下面就贴一个用户信息的实体，AcctUser.java

     

package org.andy.work.entity;// Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0import java.util.Date;import java.util.HashSet;import java.util.Set;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.FetchType;import javax.persistence.Id;import javax.persistence.JoinColumn;import javax.persistence.JoinTable;import javax.persistence.ManyToMany;import javax.persistence.Table;import javax.persistence.Temporal;import javax.persistence.TemporalType;import org.hibernate.annotations.Cache;import org.hibernate.annotations.CacheConcurrencyStrategy;import com.fasterxml.jackson.annotation.JsonIgnoreProperties;/** * AcctUser generated by hbm2java */@Entity@Table(name = "acct_user", catalog = "work")@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)public class AcctUser implements java.io.Serializable {/** *  */private static final long serialVersionUID = 6980093847795726310L;private String id;private String nickName;private String telephone;private Date registerTime;private Set<AcctRole> acctRoles = new HashSet<AcctRole>(0);public AcctUser() {}public AcctUser(String id, String nickName) {this.id = id;this.nickName = nickName;}public AcctUser(String id, String nickName, String telephone,Date registerTime, Set<AcctRole> acctRoles) {this.id = id;this.nickName = nickName;this.telephone = telephone;this.registerTime = registerTime;this.acctRoles = acctRoles;}@Id@Column(name = "id", unique = true, nullable = false, length = 36)public String getId() {return this.id;}public void setId(String id) {this.id = id;}@Column(name = "nick_name", nullable = false)public String getNickName() {return this.nickName;}public void setNickName(String nickName) {this.nickName = nickName;}@Column(name = "telephone")public String getTelephone() {return this.telephone;}public void setTelephone(String telephone) {this.telephone = telephone;}@Temporal(TemporalType.TIMESTAMP)@Column(name = "register_time", length = 19)public Date getRegisterTime() {return this.registerTime;}public void setRegisterTime(Date registerTime) {this.registerTime = registerTime;}@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})@ManyToMany(fetch = FetchType.LAZY)@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)@JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) })public Set<AcctRole> getAcctRoles() {return this.acctRoles;}public void setAcctRoles(Set<AcctRole> acctRoles) {this.acctRoles = acctRoles;}}

上面有几个需要注意的：

     上面大多数都是Hibernate tools自动生成的，但是有几个需要手动添加：

              1、如果这个实体使用二级缓存的话，需要添加@cache注解；

              2、如果该实体里面还有集合元素（set， map，list），如果实体要采用二级缓存，那么这些集合元素必须也添加@cache注解。

              3、@JsonIgnoreProperties注解是为了防止SpringMVC在json返回时产生循环输出使用，如果不配置的话就会出现json死循环（还有多对多，一对多的属性时）。

             4、@JsonIgnore这个是在转换成json是忽略该属性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})则是忽略acctRoles里面的acctUsers和acctAuthorites属性。

6、创建Dao层

6.1Dao接口

              Dao层和Service层我们肯定采用的是面相接口编程的思想，所以，我们先定义一个通用的Dao接口，GenericDao.java

            

package org.andy.work.dao;import java.io.Serializable;import java.util.List;/** * 创建时间：2015-2-6 下午2:26:42 *  * @author andy * @version 2.2 *  * Dao通用接口 */interface GenericDao<T, PK extends Serializable> {T load(PK id);T get(PK id);List<T> findAll();void persist(T entity);PK save(T entity);void saveOrUpdate(T entity);void delete(PK id);void flush();}

            在定义具体的UserDao.java接口

           

package org.andy.work.dao;import org.andy.work.entity.AcctUser;/** * 创建时间：2015-2-6 下午2:43:50 *  * @author andy * @version 2.2 *  * 用户Dao接口 */public interface UserDao extends GenericDao<AcctUser, String> {}

6.2、Dao层实现类

    我们需要将Dao层的实现类注入为bean，所以需要添加@Repository注解，UserDaoImpl如下：

package org.andy.work.dao.impl;import java.util.List;import org.andy.work.dao.UserDao;import org.andy.work.entity.AcctUser;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;/** * 创建时间：2015-2-6 下午2:45:14 *  * @author andy * @version 2.2 */@Repository("userDao")public class UserDaoImpl implements UserDao {@Autowiredprivate SessionFactory sessionFactory;private Session getCurrentSession() {return this.sessionFactory.getCurrentSession();}@Overridepublic AcctUser load(String id) {return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);}@Overridepublic AcctUser get(String id) {return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);}@SuppressWarnings("unchecked")@Overridepublic List<AcctUser> findAll() {List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();return acctUsers;}@Overridepublic void persist(AcctUser entity) {this.getCurrentSession().persist(entity);}@Overridepublic String save(AcctUser entity) {return (String) this.getCurrentSession().save(entity);}@Overridepublic void saveOrUpdate(AcctUser entity) {this.getCurrentSession().saveOrUpdate(entity);}@Overridepublic void delete(String id) {AcctUser entity = this.load(id);this.getCurrentSession().delete(entity);}@Overridepublic void flush() {this.getCurrentSession().flush();}}

7、创建Service层

  7.1、Service层接口

package org.andy.work.service;import java.util.List;import org.andy.work.entity.AcctUser;/** * 创建时间：2015-2-6 下午3:18:57 *  * @author andy * @version 2.2 *  userService接口 */public interface UserService {AcctUser load(String id);AcctUser get(String id);List<AcctUser> findAll();void persist(AcctUser entity);String save(AcctUser entity);void saveOrUpdate(AcctUser entity);void delete(String id);void flush();}

  7.2、service层实现类

   UserServiceImpl就需要注入上面定义的Dao层bean。

 

package org.andy.work.service.impl;import java.util.List;import org.andy.work.dao.UserDao;import org.andy.work.entity.AcctUser;import org.andy.work.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;/** * 创建时间：2015-2-6 下午3:24:16 *  * @author andy * @version 2.2 UserService 的实现 */@Service("userService")public class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;@Overridepublic AcctUser load(String id) {return userDao.load(id);}@Overridepublic AcctUser get(String id) {return userDao.get(id);}@Overridepublic List<AcctUser> findAll() {return userDao.findAll();}@Overridepublic void persist(AcctUser entity) {userDao.persist(entity);}@Overridepublic String save(AcctUser entity) {return userDao.save(entity);}@Overridepublic void saveOrUpdate(AcctUser entity) {userDao.saveOrUpdate(entity);}@Overridepublic void delete(String id) {userDao.delete(id);}@Overridepublic void flush() {userDao.flush();}}

8、测试Spring和Hibernate的整合

    我们可以在src/test/java编写测试类，测试上面的配置，如果测试成功已经基本大功告成。

 

package org.andy.work.service;import java.util.Date;import java.util.List;import java.util.UUID;import org.andy.work.entity.AcctUser;import org.apache.log4j.Logger;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alibaba.fastjson.JSON;/** * 创建时间：2015-2-6 下午3:31:07 *  * @author andy * @version 2.2 */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = { "classpath:spring.xml","classpath:spring-hibernate.xml" })public class TestUserService {private static final Logger LOGGER = Logger.getLogger(TestUserService.class);@Autowiredprivate UserService userService;@Testpublic void save() {AcctUser acctUser = new AcctUser();acctUser.setId(UUID.randomUUID().toString());acctUser.setNickName("andy");acctUser.setRegisterTime(new Date());acctUser.setTelephone("13022221111");String id = userService.save(acctUser);LOGGER.info(JSON.toJSONString(id));}}

9、引入SpringMVC

     添加spring-mvc.xml文件

  

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"><!-- 自动扫描@Controller注入为bean --><context:component-scan base-package="org.andy.work.controller" /><!-- 以下为SpringMVC配置 --><mvc:annotation-driven><!-- 返回json数据，@response使用 --><mvc:message-converters register-defaults="true"><beanclass="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value><value>application/json;charset=UTF-8</value></list></property></bean></mvc:message-converters></mvc:annotation-driven><!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass"value="org.springframework.web.servlet.view.JstlView" /><property name="prefix" value="/WEB-INF/views" /><property name="suffix" value=".jsp" /></bean></beans>

   上面配置了包扫描Controller，[email protected]��，和视图层的配置。

10、配置web.xml容器

      web容器是web项目的大脑，所以web容器，首先需要引入spring，让spring管理各个框架，并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。

web.xml文件如下：

 

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><display-name>springmvc_demo</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value></context-param><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- openSessionInView配置 作用是延迟session关闭到view层 --><filter><filter-name>openSessionInViewFilter</filter-name><filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class><init-param><param-name>singleSession</param-name><param-value>true</param-value></init-param></filter><!-- 监听servletContext，启动contextConfigLocation中的spring配置信息 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 防止spring内存溢出监听器 --><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><servlet><description>spring mvc servlet</description><servlet-name>rest</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><!-- 此处配置的是SpringMVC的配置文件 --><param-value>classpath:spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>rest</servlet-name><url-pattern>*.htmls</url-pattern></servlet-mapping><filter-mapping><filter-name>openSessionInViewFilter</filter-name><url-pattern>*.htmls</url-pattern></filter-mapping><!-- 配置session超时时间，单位分钟 --><session-config><session-timeout>30</session-timeout></session-config><welcome-file-list><welcome-file>/index.jsp</welcome-file></welcome-file-list></web-app>

11、创建控制层Controller

     控制层UserController

package org.andy.work.controller;import java.util.List;import org.andy.work.entity.AcctUser;import org.andy.work.service.UserService;import org.apache.log4j.Logger;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;/**   * 创建时间：2015-2-7 上午11:49:00   * @author andy   * @version 2.2   * 描述： 用户Controller */@Controller@RequestMapping("/user")public class UserController {private static final Logger LOGGER = Logger.getLogger(UserController.class);@Autowiredprivate UserService userService;@RequestMapping("/showInfo/{userId}")public String showUserInfo(ModelMap modelMap, @PathVariable String userId){LOGGER.info("查询用户：" + userId);AcctUser userInfo = userService.load(userId);modelMap.addAttribute("userInfo", userInfo);return "/user/showInfo";}@RequestMapping("/showInfos")public @ResponseBody List<AcctUser> showUserInfos(){LOGGER.info("查询用户全部用户");List<AcctUser> userInfos = userService.findAll();return userInfos;}}

12、创建视图层

   在src/main/webapp/WEB-INF/views下 创建user/showInfo.jsp

      

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%><%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%><%String path = request.getContextPath();String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><base href="<%=basePath%>" /><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><script type="text/javascript" src="js/jquery-1.9.1.min.js"></script><title>userInfo</title></head><body>用户信息 昵称： ${userInfo.nickName} 用户id：${userInfo.id} 用户电话:${userInfo.telephone } 注册时间：<fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" />角色：[<c:forEach items="${ userInfo.acctRoles}" var="role">                    ${role.name }   权限[                       <c:forEach items="${ role.acctAuthorities}" var="authority">                         ${authority.name }                        </c:forEach> ]                  </c:forEach>]<br /> ajax显示全部用户信息：<div id="show_all_user"></div></body><script type="text/javascript">$.ajax({type : "get",url : "user/showInfos.htmls",dataType : "json",success : function(data) {$(data).each(function(i, user) {var p = "<p>昵称:" + user.nickName + "    电话:"+ user.telephone + "    注册时间:"+ user.registerTime + "    id:" + user.id +"</p>";$("#show_all_user").append(p);});},async : true});</script></html>

13、部署服务器测试

          使用Maven打包部署：clean compile  package

          部署到tomcat，测试

          主要测试上面的  http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls

                                  和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls  （json数据返回）

          上面视图层就包含了这两条url请求的测试：

       

     ok，到此Spring+SpringMVC+Hibernate搭建完毕。
