SpringMVC又一个漂亮的web框架，他与Struts2并驾齐驱，Struts出世早而占据了一定优势，我在博客《[Struts1+Hibernate+Spring][Struts1_Hibernate_Spring][整合实例][Struts1_Hibernate_Spring]》中做了一个简单的实例，介绍了SSH1的基本搭建方式，Struts2是根据Struts1发展而来，博客中就没有贴SSH2的例子，只对比了下Struts1和Struts2异同，通过对比，SSH2的搭建基本不在话下了。下面同样做一个简单的应用实例，介绍SpringMVC的基本用法，接下来的博客也将梳理一下Struts2和SpringMVC的一些异同，通过梳理和旧知识的联系，让学习的成本变低，花很短的时间就可以了解一门貌似新的技术，其实本质没变。

下面开始实例，这个实例的需求是对用户信息进行增删改查。首先创建一个web项目test\_ssh，目录结构及需要的Jar包如下图：

![20130531104340020][]

![20130531104345457][]![20130531104350910][]

创建一个User实体类，放在Entity包下，采用注解的方式：

**\[java\]** [view plain][] [copy][view plain]

1.  package com.tgb.entity;
2.  
3.  import javax.persistence.Column;
4.  import javax.persistence.Entity;
5.  import javax.persistence.GeneratedValue;
6.  import javax.persistence.Id;
7.  import javax.persistence.Table;
8.  
9.  import org.hibernate.annotations.GenericGenerator;
10. 
11. @Entity
12. @Table(name="T\_USER")
13. public class User \{
14. 
15. @Id
16. @GeneratedValue(generator="system-uuid")
17. @GenericGenerator(name = "system-uuid",strategy="uuid")
18. @Column(length=32)
19. private String id;
20. 
21. @Column(length=32)
22. private String userName;
23. 
24. @Column(length=32)
25. private String age;
26. 
27. public String getId() \{
28. return id;
29. \}
30. 
31. public void setId(String id) \{
32. this.id = id;
33. \}
34. 
35. public String getUserName() \{
36. return userName;
37. \}
38. 
39. public void setUserName(String userName) \{
40. this.userName = userName;
41. \}
42. 
43. public String getAge() \{
44. return age;
45. \}
46. 
47. public void setAge(String age) \{
48. this.age = age;
49. \}
50. 
51. \}

本篇关于SpringMVC基本都会采用注解的方式，首先配置好数据源以及事务[spring][]\-common.xml，放在config.spring包下：

**\[html\]** [view plain][] [copy][view plain]

1.  <?xml version="1.0" encoding="UTF-8"?>
2.  <beans xmlns="http://www.springframework.org/schema/beans"
3.  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4.  xmlns:context="http://www.springframework.org/schema/context"
5.  xmlns:mvc="http://www.springframework.org/schema/mvc"
6.  xsi:schemaLocation="http://www.springframework.org/schema/beans
7.  http://www.springframework.org/schema/beans/spring-beans.xsd">
8.  
9.  
10. <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
11. <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
12. <property name="url" value="jdbc:mysql://localhost/test\_ssh"></property>
13. <property name="username" value="root"></property>
14. <property name="password" value="1"></property>
15. </bean>
16. 
17. 
18. <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
19. <property name="dataSource" ref="dataSource" />
20. <property name="hibernateProperties">
21. <props>
22. <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
23. <prop key="hibernate.hbm2ddl.auto">update</prop>
24. <prop key="hibernate.show\_sql">true</prop>
25. <prop key="hibernate.format\_sql">true</prop>
26. </props>
27. </property>
28. <property name="annotatedClasses">
29. <list>
30. <value>com.tgb.entity.User</value>
31. </list>
32. </property>
33. </bean>
34. 
35. 
36. <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
37. <property name="sessionFactory" ref="sessionFactory"/>
38. </bean>
39. 
40. 
41. <bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">
42. <property name="transactionManager" ref="transactionManager"></property>
43. <property name="transactionAttributes">
44. <props>
45. <prop key="add\*">PROPAGATION\_REQUIRED,-Exception</prop>
46. <prop key="modify\*">PROPAGATION\_REQUIRED,-myException</prop>
47. <prop key="del\*">PROPAGATION\_REQUIRED</prop>
48. <prop key="\*">PROPAGATION\_REQUIRED</prop>
49. </props>
50. </property>
51. </bean>
52. </beans>

然后配置关于SpringMVC的内容，下面配置中都有注释说明，就不再赘述，spring-mvc.xml放在config.spring包下：

**\[html\]** [view plain][] [copy][view plain]

完成这些共用的配置之后，来配置web项目起点web.xml：

**\[html\]** [view plain][] [copy][view plain]

1.  <?xml version="1.0" encoding="UTF-8"?>
2.  <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">
3.  <display-name>json\_test</display-name>
4.  <welcome-file-list>
5.  <welcome-file>login.jsp</welcome-file>
6.  </welcome-file-list>

59. <url-pattern>/\*</url-pattern>
60. </filter-mapping>
61. </web-app>

读者需自行下载[jQuery][]包，放到webContent文件夹下的[js][]包下。然后创建几个[测试][Link 1]页面，分别如下：

**\[html\]** [view plain][] [copy][view plain]

1.  <h5><a href="/test\_ssh/user/getAllUser">进入用户管理页</a></h5>

Index.jsp，用户管理的主界面

**\[html\]** [view plain][] [copy][view plain]

1.  <%@ page language="java" contentType="text/html; charset=UTF-8"
2.  pageEncoding="UTF-8"%>
3.  <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
4.  <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
5.  <html>
6.  <head>
7.  <script type="text/javascript" src="../js/jquery-1.7.1.js"></script>
8.  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
9.  <title>Insert title here</title>
10. <script type="text/javascript">
11. function del(id)\{
12. $.get("/test\_ssh/user/delUser?id=" + id,function(data)\{
13. if("success" == data.result)\{
14. alert("删除成功");
15. window.location.reload();
16. \}else\{
17. alert("删除失败");
18. \}
19. \});
20. \}
21. </script>
22. </head>
23. <body>
24. <h6><a href="/test\_ssh/user/toAddUser">添加用户</a></h6>
25. <table border="1">
26. <tbody>
27. <tr>
28. <th>姓名</th>
29. <th>年龄</th>
30. <th>操作</th>
31. </tr>
32. <c:if test="$\{!empty userList \}">
33. <c:forEach items="$\{userList \}" var="user">
34. <tr>
35. <td>$\{user.userName \}</td>
36. <td>$\{user.age \}</td>
37. <td>
38. <a href="/test\_ssh/user/getUser?id=$\{user.id \}">编辑</a>
39. <a href="javascript:del('$\{user.id \}')">删除</a>
40. </td>
41. </tr>
42. </c:forEach>
43. </c:if>
44. </tbody>
45. </table>
46. </body>
47. </html>

addUser.jsp，添加用户界面

**\[html\]** [view plain][] [copy][view plain]

1.  <%@ page language="java" contentType="text/html; charset=UTF-8"
2.  pageEncoding="UTF-8"%>
3.  <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4.  <html>
5.  <head>
6.  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
7.  <title>Insert title here</title>
8.  <script type="text/javascript">
9.  function addUser()\{
10. var form = document.forms\[0\];
11. form.action = "/test\_ssh/user/addUser";
12. form.method="post";
13. form.submit();
14. \}
15. </script>
16. </head>
17. <body>
18. <h1>添加用户</h1>
19. <form action="" name="userForm">
20. 姓名：<input type="text" name="userName">
21. 年龄：<input type="text" name="age">
22. <input type="button" value="添加" οnclick="addUser()">
23. </form>
24. </body>
25. </html>

editUser.jsp，修改用户信息界面。

**\[html\]** [view plain][] [copy][view plain]

还有success.jsp和error.jsp页面，无代码，就不再展示。

然后

首先是web包下属于的control层的类UserController，这相当于Struts中的Action，是重要的类：

**\[java\]** [view plain][view plain 1] [copy][view plain 1]

1.  package com.tgb.web;
2.  
3.  import java.io.IOException;
4.  import java.io.PrintWriter;
5.  
6.  import javax.annotation.Resource;
7.  import javax.servlet.http.HttpServletRequest;
8.  import javax.servlet.http.HttpServletResponse;
9.  
10. import org.springframework.stereotype.Controller;
11. import org.springframework.web.bind.annotation.RequestMapping;
12. 
13. import com.tgb.entity.User;
14. import com.tgb.manager.UserManager;
15. 
16. @Controller
17. @RequestMapping("/user")
18. public class UserController \{
19. 
20. @Resource(name="userManager")
21. private UserManager userManager;
22. 
23. @RequestMapping("/getAllUser")
24. public String getAllUser(HttpServletRequest request)\{
25. 
26. request.setAttribute("userList", userManager.getAllUser());
27. 
28. return "/index";
29. \}
30. 
31. @RequestMapping("/getUser")
32. public String getUser(String id,HttpServletRequest request)\{
33. 
34. request.setAttribute("user", userManager.getUser(id));
35. 
36. return "/editUser";
37. \}
38. 
39. @RequestMapping("/toAddUser")
40. public String toAddUser()\{
41. return "/addUser";
42. \}
43. 
44. @RequestMapping("/addUser")
45. public String addUser(User user,HttpServletRequest request)\{
46. 
47. userManager.addUser(user);
48. 
49. return "redirect:/user/getAllUser";
50. \}
51. 
52. @RequestMapping("/delUser")
53. public void delUser(String id,HttpServletResponse response)\{
54. 
55. String result = "\{\\"result\\":\\"error\\"\}";
56. 
57. if(userManager.delUser(id))\{
58. result = "\{\\"result\\":\\"success\\"\}";
59. \}
60. 
61. response.setContentType("application/json");
62. 
63. try \{
64. PrintWriter out = response.getWriter();
65. out.write(result);
66. \} catch (IOException e) \{
67. e.printStackTrace();
68. \}
69. \}
70. 
71. @RequestMapping("/updateUser")
72. public String updateUser(User user,HttpServletRequest request)\{
73. 
74. if(userManager.updateUser(user))\{
75. user = userManager.getUser(user.getId());
76. request.setAttribute("user", user);
77. return "redirect:/user/getAllUser";
78. \}else\{
79. return "/error";
80. \}
81. \}
82. \}

然后是属于manager包下的业务逻辑类，接口UserManager：

**\[java\]** [view plain][view plain 1] [copy][view plain 1]

1.  package com.tgb.manager;
2.  
3.  import java.util.List;
4.  
5.  import com.tgb.entity.User;
6.  
7.  public interface UserManager \{
8.  
9.  public User getUser(String id);
10. 
11. public List<User> getAllUser();
12. 
13. public void addUser(User user);
14. 
15. public boolean delUser(String id);
16. 
17. public boolean updateUser(User user);
18. \}

实现类UserManagerImpl：

**\[java\]** [view plain][view plain 1] [copy][view plain 1]

1.  package com.tgb.manager;
2.  
3.  import java.util.List;
4.  
5.  import com.tgb.dao.UserDao;
6.  import com.tgb.entity.User;
7.  
8.  public class UserManagerImpl implements UserManager \{
9.  
10. private UserDao userDao;
11. 
12. public void setUserDao(UserDao userDao) \{
13. this.userDao = userDao;
14. \}
15. 
16. @Override
17. public User getUser(String id) \{
18. return userDao.getUser(id);
19. \}
20. 
21. @Override
22. public List<User> getAllUser() \{
23. return userDao.getAllUser();
24. \}
25. 
26. @Override
27. public void addUser(User user) \{
28. userDao.addUser(user);
29. \}
30. 
31. @Override
32. public boolean delUser(String id) \{
33. 
34. return userDao.delUser(id);
35. \}
36. 
37. @Override
38. public boolean updateUser(User user) \{
39. return userDao.updateUser(user);
40. \}
41. 
42. \}

最后是属于dao包底下的DAO层，主要由[hibernate][spring]完成。接口UserDao：

**\[java\]** [view plain][view plain 1] [copy][view plain 1]

1.  package com.tgb.dao;
2.  
3.  import java.util.List;
4.  
5.  import com.tgb.entity.User;
6.  
7.  public interface UserDao \{
8.  
9.  public User getUser(String id);
10. 
11. public List<User> getAllUser();
12. 
13. public void addUser(User user);
14. 
15. public boolean delUser(String id);
16. 
17. public boolean updateUser(User user);
18. \}

实现类UserDaoImpl：

**\[java\]** [view plain][view plain 1] [copy][view plain 1]

1.  package com.tgb.dao;
2.  
3.  import java.util.List;
4.  
5.  import org.hibernate.Query;
6.  import org.hibernate.SessionFactory;
7.  
8.  import com.tgb.entity.User;
9.  
10. public class UserDaoImpl implements UserDao \{
11. 
12. private SessionFactory sessionFactory;
13. 
14. public void setSessionFactory(SessionFactory sessionFactory) \{
15. this.sessionFactory = sessionFactory;
16. \}
17. 
18. @Override
19. public User getUser(String id) \{
20. 
21. String hql = "from User u where u.id=?";
22. Query query = sessionFactory.getCurrentSession().createQuery(hql);
23. query.setString(0, id);
24. 
25. return (User)query.uniqueResult();
26. \}
27. 
28. @Override
29. public List<User> getAllUser() \{
30. 
31. String hql = "from User";
32. Query query = sessionFactory.getCurrentSession().createQuery(hql);
33. 
34. return query.list();
35. \}
36. 
37. @Override
38. public void addUser(User user) \{
39. sessionFactory.getCurrentSession().save(user);
40. \}
41. 
42. @Override
43. public boolean delUser(String id) \{
44. 
45. String hql = "delete User u where u.id = ?";
46. Query query = sessionFactory.getCurrentSession().createQuery(hql);
47. query.setString(0, id);
48. 
49. return (query.executeUpdate() > 0);
50. \}
51. 
52. @Override
53. public boolean updateUser(User user) \{
54. 
55. String hql = "update User u set u.userName = ?,u.age=? where u.id = ?";
56. Query query = sessionFactory.getCurrentSession().createQuery(hql);
57. query.setString(0, user.getUserName());
58. query.setString(1, user.getAge());
59. query.setString(2, user.getId());
60. 
61. return (query.executeUpdate() > 0);
62. \}
63. 
64. \}

最后外加一个配置[spring][]\-beans.xml，放在config.spring包下，负责为各层依赖注入需要的对象：

**\[html\]** [view plain][view plain 1] [copy][view plain 1]

到此为止，所有的配置和代码完成，部署—运行，运行结果如下图：

![20130531110906336][]

![20130531110911867][]![20130531110920758][]
