Spring-SpringMVC-Hibernate整合

由于没有使用maven所以直接看包结构吧！后续可能会带有maven的！

spring-common.xml相当于applicationContext.xml

<span style="font-family: Arial, Helvetica, sans-serif;"><?xml version="1.0" encoding="UTF-8"?></span>

<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"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans.xsd"><!--配置数据源 --><bean id="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="com.mysql.jdbc.Driver"></property><property name="url" value="jdbc:mysql://localhost:3306/test"></property><property name="username" value="root"></property><property name="password" value="root"></property></bean><!--配置SessionFactory --><bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><!--配置数据库方言 --><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop></props></property><property name="packagesToScan"><list><value>com.iss.model</value></list></property></bean><!-- 配置一个事务管理器 --><bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean><!-- 配置事务，使用代理的方式 --><bean id="transactionProxy"class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"abstract="true"><property name="transactionManager" ref="transactionManager"></property><property name="transactionAttributes"><props><prop key="add*">PROPAGATION_REQUIRED,-Exception</prop><prop key="modify*">PROPAGATION_REQUIRED,-myException</prop><prop key="del*">PROPAGATION_REQUIRED</prop><prop key="*">PROPAGATION_REQUIRED</prop></props></property></bean></beans>

还有一个就是SpringMVC的配置文件

spring-mvc.xml

<?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"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"><!-- 注解扫描包 --><context:component-scan base-package="com.iss" /><!-- 开启注解 --><mvc:annotation-driven /><!-- 静态资源(js/image)的访问 --><mvc:resources location="/js/" mapping="/js/**" /><!-- 定义视图解析器 --><bean id="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean></beans>

最后是web.xml

<?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>json_test</display-name><welcome-file-list><welcome-file>login.jsp</welcome-file></welcome-file-list><!-- 加载所有的配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring-*.xml</param-value></context-param><!-- 配置Spring监听 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置SpringMVC --><servlet><servlet-name>springMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>WEB-INF/classes/spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springMVC</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!-- 配置字符集 --><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><!-- 配置Session --><filter><filter-name>openSession</filter-name><filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class></filter><filter-mapping><filter-name>openSession</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

好了所有的配置文件能完成了下面看逻辑代码。

com.iss.model.User.class

package com.iss.model;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.Table;/** * @author dell *  */@Entity@Table(name = "user")public class User {private int id;private String name;@Id@GeneratedValue(strategy = GenerationType.AUTO)public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

com.iss.dao.UserDao.class

package com.iss.dao;import java.util.List;import com.iss.model.User;public interface UserDao {public User addUser(User user);public List<User> getAllUsers();public User getUser(int userId);public void deleteUser(User user);}

com.iss.dao.impl.UserDaoImpl.class

package com.iss.dao.impl;import java.util.List;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import com.iss.dao.UserDao;import com.iss.model.User;@Repositorypublic class UserDaoImpl implements UserDao {private SessionFactory sessionFactory;@Autowiredpublic void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}public User addUser(User user) {Session session = sessionFactory.getCurrentSession();session.saveOrUpdate(user);session.flush();return user;}public List<User> getAllUsers() {Session session = sessionFactory.getCurrentSession();Query query = session.createQuery("from User");List<User> users = query.list();session.flush();return users;}public User getUser(int userId) {Session session = sessionFactory.getCurrentSession();User user = (User) session.get(User.class, userId);return user;}public void deleteUser(User user) {Session session = sessionFactory.getCurrentSession();session.delete(user);session.flush();}}

com.iss.service.UserService.class

package com.iss.service;import java.util.List;import com.iss.model.User;public interface UserService {public User addUser(User user);public List<User> getAllUsers();public User getUser(int userId);public void deleteUser(User user);}

com.iss.service.UserServiceImpl.class

package com.iss.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.iss.dao.UserDao;import com.iss.model.User;import com.iss.service.UserService;@Service("UserService")public class UserServiceImpl implements UserService {private UserDao userDao;@Autowiredpublic void setUserDao(UserDao userDao) {this.userDao = userDao;}public User addUser(User user) {// TODO Auto-generated method stubreturn userDao.addUser(user);}public List<User> getAllUsers() {// TODO Auto-generated method stubreturn userDao.getAllUsers();}public User getUser(int userId) {// TODO Auto-generated method stubreturn userDao.getUser(userId);}public void deleteUser(User user) {userDao.deleteUser(user);}}

com.iss.controller.UserController

package com.iss.controller;import java.io.IOException;import java.util.List;import javax.servlet.http.HttpServletResponse;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.iss.model.User;import com.iss.service.UserService;@Controller@RequestMapping("/user")public class UserController {private UserService userService;@Autowiredpublic void setUserService(UserService userService) {this.userService = userService;}@RequestMapping("/toAddUser")public String toAddUser() {return "addUser";}@RequestMapping("/toUpdateUser")public String toUpdateUser(int id, ModelMap modelMap) {User user = userService.getUser(id);modelMap.addAttribute("user", user);return "editUser";}@RequestMapping("/addUser")public String addUser(User user) {userService.addUser(user);return "redirect:/user/getAllUser";}@RequestMapping("/getAllUser")public String getAllUsers(ModelMap modelMap) {List<User> userList = userService.getAllUsers();modelMap.addAttribute("userList", userList);return "index";}@RequestMapping("/delUser")public String delUser(int id, HttpServletResponse response)throws IOException {User user = userService.getUser(id);System.err.println(user.getName());userService.deleteUser(user);response.getWriter().print("success");return null;}}

下面是几个jsp页面的代码

login.jsp

<body><h5><a href="user/getAllUser">进入用户管理页</a></h5></body>

index.jsp

<body><h6><a href="toAddUser">添加用户</a></h6><table border="1"><tbody><tr><th>姓名</th><th>年龄</th><th>操作</th></tr><c:if test="${!empty userList }"><c:forEach items="${userList }" var="user"><tr id="tr${user.id }"><td>${user.id }</td><td>${user.name}</td><td><a href="toUpdateUser?id=${user.id }">编辑</a> <ahref="javascript:del(${user.id })">删除</a></td></tr></c:forEach></c:if></tbody></table></body>

其中删除用了Jquery需引用？Jquery包

<script type="text/javascript" src="../js/jQuery.js"></script><script type="text/javascript">function del(id) {/* $.get("delUser?id=" + id, function(data) {alert(data);if ("success" == data) {alert("删除成功");$("#tr" + id).remove();} else {alert("删除失败");}}); */var url = "delUser?id=" + id;$.ajax({type : "post",url : url,dataType : "text",success : function(data) {if ("success" == data) {alert("删除成功");$("#tr" + id).remove();} else {alert("删除失败");}}});}</script>

editUser.jsp

<h1>编辑用户</h1><form action="addUser" name="userForm" method="post"><input type="hidden" name="id" value="${user.id }"> 姓名：<inputtype="text" name="name" value="${user.name }"> <inputtype="submit" value="编辑"></form>

addUser.jsp

<body><h1>添加用户</h1><form action="" name="userForm">姓名：<input type="text" name="name"> <input type="button"value="添加" onclick="addUser()"></form></body>

其中js代码

<script type="text/javascript">function addUser() {var form = document.forms[0];form.action = "addUser";form.method = "post";form.submit();}</script>

以上基本完成了Spring-SpringMVC-Hibernate之间的整合并进行了基本的crud操作。当然还有许多不足之处还望轻喷！
