Spring2.5 + Hibernate3.2 集成实例(CTO)

首先需要准备SPRING和HIBERNATE 相应的JAR包,在ECLIPSE 中新建一个WEB工程,将解压的SPRING中的 /dist/modules 下的JAR和HIBERNATE 中的 hibernate3.jar 和 /lib/ 目录下的包全部拷入到工程的LIB目录,这时我们就可以真正开始编写SPRING+HIBERNATE应用了,首先我们建立一个SPRING的控制器,代码清单如下:

 package com.spring25.action;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import com.spring25.service.ILoginService;/* 描述该bean为springMVC控制器，将由spring容器来创建和管理 */@Controllerpublic class LoginController {/* 自动装载 */@Autowiredprivate ILoginService loginService;/* 将该控制器的login方法与login.do 的请求进行关联,真正实现控制功能的是 @RequestMapping 注解 *//* * springMVC 控制请求处理的方式有如下几种: * 1、直接在class头加 @RequestMapping("login.do"),能后在请求处理的方法头上加@RequestMapping,表明该请求由该控制器的该方法处理 * 2、在方法头上加 @RequestMapping("login.do"),当该请求到达时将会调用这个方法处理 * 3、通过参数：该控制处理的请求地址只有一个,但又想通过参数来调用不同的方法,这个时候就可以在类的头上加@RequestMapping("users.do") * 处理方法头上加@RequestMapping(params="method=login"),这是一个分流规则,其中 method=login就是请求中带的参数 * 4、根据特殊的表单提交方法进行处理,如: @RequestMapping(params="method=login",method=RequestMethod.POST) * 这样只能当提交方法是 POST 时 login 方法才会处理该请求 * */@RequestMapping("/login.do")public String login(String userName,String password,ModelMap model){boolean succeed = this.getLoginService().login(userName,password);model.addAttribute("userName", userName);/* 返回一个String,该名称应为逻辑视图的名称 */if(succeed){return "error";}return "success";}}

HIBERNATE 持久类

package com.spring25.hibernate;import java.io.Serializable;import java.util.Date;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.Table;@SuppressWarnings("serial")@Entity@Table(name="users") //持久类与表的映射public class Users implements Serializable{private Integer uid;private String userName; private String password;private Date birthday;public Users(){}@Id@GeneratedValuepublic Integer getUid() {return uid;}public void setUid(Integer uid) {this.uid = uid;}@Column(name="username",nullable=true,length=20)public String getUserName() {return userName;} public void setUserName(String userName) {this.userName = userName;}public void setPassword(String password) {this.password= password;} @Column(name="password",nullable=true,length=20)public String getPassword() {return password;}@Column(name="birthday")public Date getBirthday() {return birthday;}public void setBirthday(Date birthday) {this.birthday = birthday;}}

接下来建立一个业务类

package com.spring25.service.impl;import com.spring25.dao.ILoginDao;import com.spring25.service.ILoginService;public class LoginService implements ILoginService { private ILoginDao loginDao; public ILoginDao getLoginDao() { return loginDao; } public void setLoginDao(ILoginDao loginDao) { this.loginDao = loginDao; } public boolean login(String userName,String password) { return this.getLoginDao().login(userName,password); }}

数据处理层代码

package com.spring25.dao.impl;import org.hibernate.Query;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.spring25.dao.ILoginDao;public class LoginDaoImpl extends HibernateDaoSupport implements ILoginDao{public boolean login(String userName,String password) {Query query = this.getSession(true).createQuery("from Users where userName=:userName and password=:password");query.setParameter("userName", userName);query.setparameter("password",password);if(query.list().size() > 0){return true;}return false;}}

接下来我们需要添加SPRING配置文件,其中applicationContext.xml为业务层配置,spring25annmvc-servlet.xml 声明SPRING MVC 相应配置

spring25annmvc-servlet.xml 内容如下：

 <?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: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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <!-- 在web.xml 中配置了 spring25annmvc 的模块,根据spring的规范,需要在 spring25annmvc-servlet.xml 定义springMVC的具体配置 --> <!-- 对 action 包中的所有 Controller 类进行扫描,以完成自动装载功能 --> <context:component-scan base-package="com.spring25.action"></context:component-scan> <!-- 启动springMVC的注解驱动 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></bean> <!-- 模型视图的解析 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:suffix=".jsp"></bean> </beans>

applicationContext.xml 配置如下：

<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"><!-- JDBC 数据源 --><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"></property><property name="url" value="jdbc:microsoft:sqlserver://192.168.0.180:1433;databaseName=pubs"></property><property name="username" value="holpe"></property><property name="password" value="holpe20080801"></property></bean><bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop><prop key="hibernate.show_sql">false</prop></props></property><property name="annotatedClasses"><list><value>com.spring25.hibernate.Users</value></list></property></bean><!-- hibernate 模板,用来代替 sessionFactory --><bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"><property name="sessionFactory" ref="sessionFactory"/><property name="cacheQueries" value="true"/></bean><bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="dataSource" ref="dataSource"/><property name="sessionFactory" ref="sessionFactory"/></bean><!-- 声明式事务管理 --><aop:config><aop:pointcut id="servicePointcut" expression="execution(* com.spring25.service.*.*(..))"/><aop:advisor advice-ref="txAdvice" pointcut-ref="servicePointcut"/></aop:config><!--事务控制--><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="login*" read-only="true"/></tx:attributes></tx:advice><bean id="loginDao" class="com.spring25.dao.impl.LoginDaoImpl"><property name="hibernateTemplate" ref="hibernateTemplate"/></bean> <bean id="loginService" class="com.spring25.service.impl.LoginService"> <property name="loginDao" ref="loginDao"/> </bean></beans>

最后配置web.xml 和建立相应 jsp 文件

web.xml 代码如下:

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- spring 相关配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <!-- spring 启动监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 处理请求的 servlet,它将加载 WEB-INF/spring25annmvc-servlet.xml下的配置文件,以启动springMVC模块 --> <servlet> <servlet-name>spring25annmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring25annmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list></web-app>

login.jsp

<%@ page language="java" contentType="text/html;charset=UTF-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title>login</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> </head> <body> <form action="login.do"> userName:<input type="text" name="userName" size=15> <br /> passWord:<input type="password" name="password" size="15"> <br /> <input type="submit" value="login"> </form> </body></html>

好了，以上就是整个编写的过程,是不是很简单呢！ 经过运行后完全正确
