因为没有使用maven所以直接看包结构吧！兴许可能会带有maven的！

Spring-SpringMVC-Hibernate整合_spring Spring-SpringMVC-Hibernate整合_java_02

包有点多，可是不要在乎这些细节，多总比少好。以下看配置文件spring-common.xml(相当于applicationContext.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.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>

另一个就是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.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-3.2.xsd
  http://www.springframework.org/schema/mvc
  http://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)的訪问 -->
  <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>

  <!-- 载入全部的配置文件 -->
  <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>

好了全部的配置文件能完毕了以下看逻辑代码。

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;

@Repository
public class UserDaoImpl implements UserDao {

  private SessionFactory sessionFactory;

  @Autowired
  public 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;

  @Autowired
  public void setUserDao(UserDao userDao) {
    this.userDao = userDao;
  }

  public User addUser(User user) {
    // TODO Auto-generated method stub
    return userDao.addUser(user);
  }

  public List<User> getAllUsers() {
    // TODO Auto-generated method stub
    return userDao.getAllUsers();
  }

  public User getUser(int userId) {
    // TODO Auto-generated method stub
    return 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;

  @Autowired
  public 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;

  }

}

以下是几个jsp页面的代码

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

</body>

index.jsp

<body>
  <h6>
    <a href="toAddUser">加入用户</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> <a
              href="javascript:del(${user.id })">删除</a>
            </td>
          </tr>
        </c:forEach>
      </c:if>
    </tbody>
  </table>
</body>

当中删除用了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="${user.id }"> 姓名：<input
      type="text" name="name" value="${user.name }"> <input
      type="submit" value="编辑">
  </form>

addUser.jsp

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

当中js代码

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

以上基本完毕了Spring-SpringMVC-Hibernate之间的整合并进行了主要的crud操作。当然还有很多不足之处还望轻喷！
