1、引入SrpingMVC所使用的Java包：

cglib-nodep-2.1_3.jar、commons-logging.jar、spring-aspects-4.1.7.RELEASE.jar、spring-beans-4.1.7.RELEASE.jar、spring-context-4.1.7.RELEASE.jar

、spring-core-4.1.7.RELEASE.jar、spring-web-4.1.7.RELEASE.jar、spring-webmvc-4.1.7.RELEASE.jar

2、新建Web项目，配置Web.xml:

  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_3_0.xsd" id="WebApp_ID" version="3.0">
  3.   <display-name>springmvc</display-name>
  4.   <!-- 配置Spring -->
  5.   <listener>
  6.     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  7.   </listener>
  8.   <!-- 配置SpringMVC的编码格式 -->
  9.   <filter>  
  10.     <filter-name>CharacterEncodingFilter</filter-name>  
  11.     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
  12.     <init-param>  
  13.         <param-name>encoding</param-name>  
  14.         <param-value>UTF-8</param-value>  
  15.     </init-param>  
  16.   </filter>
  17.   <filter-mapping>  
  18.          <filter-name>CharacterEncodingFilter</filter-name>  
  19.          <url-pattern>/*</url-pattern>  
  20.   </filter-mapping> 
  21.    <!-- 加载其他的配置文件 --> 
  22.   <context-param>
  23.     <param-name>contextConfigLocation</param-name>
  24.     <param-value>/WEB-INF/spring-servlet.xml</param-value>
  25.   </context-param>  
  26.    <!-- 配置Spring的前置控制器DispatcherServlet --> 
  27.   <servlet>
  28.         <servlet-name>spring</servlet-name>
  29.             <servlet-class>
  30.                 org.springframework.web.servlet.DispatcherServlet
  31.             </servlet-class>
  32.         <load-on-startup>1</load-on-startup>
  33.    </servlet>
  34.    <!-- 配置Spring的url后缀 --> 
  35.    <servlet-mapping>
  36.         <servlet-name>spring</servlet-name>
  37.         <url-pattern>*.do</url-pattern>
  38.    </servlet-mapping>
  39. </web-app>

3、配置spring-servlet.xml

（基中的部分MVC的配置可另外再分一个bean.xml配置，这里为了方便统一放在一个里面）:

  1. <beans xmlns="http://www.springframework.org/schema/beans"
  2.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3.     xmlns:context="http://www.springframework.org/schema/context"
  4.     xmlns:mvc="http://www.springframework.org/schema/mvc"
  5.     xsi:schemaLocation="http://www.springframework.org/schema/beans 
  6.     http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
  7.     http://www.springframework.org/schema/context
  8.     http://www.springframework.org/schema/context/spring-context-4.1.xsd 
  9.     http://www.springframework.org/schema/mvc
  10.     http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
  12.    <!-- controller方法调用规则：通过url中的method参数指定要执行的controller方法-->  
  13.     <bean id="methodNameResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">  
  14.             <property name="paramName" value="action" />  
  15.         <property name="defaultMethodName" value="view" />
  16.     </bean>
  17.     <!-- 配置MVC的前缀（prefix）和后缀（suffix） -->
  18.     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  19.         <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 
  20.        <!--  <property name="prefix" value="/WEB-INF/" /> -->
  21.         <property name="suffix" value=".jsp" />
  22.     </bean>
  23.     <!-- 以下是 控制器的配置 -->
  24.     <bean name="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping" >
  25.           <property name="order" value="1" />
  26.           <property name="mappings">
  27.                <props>
  28.                    <prop key="user.do">userController</prop>
  29.                    <prop key="index.do">indexController</prop>
  30.                </props>
  31.           </property>
  32.       </bean>      
  33.     <bean name="userController"  class="cn.raffaello.controller.UserController">
  34.         <property name="userIService" ref="userIService"></property>
  35.     </bean>
  36.     <bean name="indexController"  class="cn.raffaello.controller.IndexController" />
  37.     <!-- ServiceBean的配置 -->
  38.     <bean name="userIService" class="cn.raffaello.service.impl.UserServiceImpl" />
  39. </beans>

4、新建Model，User:

  1. public class User {
  2.     private Integer id;
  3.     private String name;
  4.     public Integer getId() {
  5.         return id;
  6.     }
  7.     public void setId(Integer id) {
  8.         this.id = id;
  9.     }
  10.     public String getName() {
  11.         return name;
  12.     }
  13.     public void setName(String name) {
  14.         this.name = name;
  15.     }
  16. }

5、新建ServiceBean并实现一个模拟的数据保存添加操作：

  1. public interface UserIService {
  2.     void saveOrUpdate(User user);
  3.     User getUserById(Integer id);
  4.     void delete(Integer id);
  5.     List<User> getUsers();
  6.     Integer getNewId();
  7. }
  9. public class UserServiceImpl implements UserIService {
  10.     private Map<Integer,Object> map=new HashMap<Integer,Object>();
  11.     private Map<String,Integer> idCount=new HashMap<String,Integer>();
  12.     @Override
  13.     public void saveOrUpdate(User user) {
  14.         map.put(user.getId(), user);
  15.     }
  16.     @Override
  17.     public User getUserById(Integer id) {
  18.         if(map.containsKey(id)){
  19.             return (User)map.get(id);
  20.         }
  21.         return new User();
  22.     }
  23.     @Override
  24.     public void delete(Integer id) {
  25.         map.remove(id);
  26.     }
  27.     @Override
  28.     public List<User> getUsers() {
  29.         List<User> list=new ArrayList<User>();
  30.         for(Integer key : map.keySet()){
  31.             list.add((User)map.get(key));
  32.         }
  33.         return list;
  34.     }
  35.     @Override
  36.     public Integer getNewId() {
  37.         if(!idCount.containsKey("ids")){
  38.             Integer id=1;
  39.             idCount.put("ids", id);
  40.             return id;
  41.         }else{
  42.             Integer id=idCount.get("ids");
  43.             id=id+1;
  44.             idCount.put("ids", id);
  45.             return id;
  46.         }
  47.     }
  48. }

6、新建控制器UserController：

  1. public class UserController implements Controller{
  2.     private UserIService userIService;
  3.     @Override
  4.     public ModelAndView handleRequest(HttpServletRequest req,
  5.             HttpServletResponse res) throws Exception {
  6.         String param="";
  7.         param=req.getParameter("param");
  8.         //新增控制器跳转
  9.         if(param.trim().equals("add")){
  10.             return new ModelAndView("/WEB-INF/userAdd");
  11.         }else if(param.trim().equals("edit")){
  12.             //编辑控制器跳转
  13.             Integer id=-1;
  14.             if(!req.getParameter("userId").trim().equals("")){
  15.                 id=Integer.parseInt(req.getParameter("userId").trim());
  16.             }
  17.             User user=userIService.getUserById(id);
  18.             req.setAttribute("user", user);
  19.             return new ModelAndView("/WEB-INF/userAdd");
  20.         }else if(param.trim().equals("userList")){
  21.             //列表页面跳转
  22.             List<User> list=userIService.getUsers();
  23.             req.setAttribute("userList", list);
  24.             return new ModelAndView("/WEB-INF/userList");
  25.         }else if(param.trim().equals("save")){
  26.             //新增的保存操作
  27.             User user=new User();
  28.             String name=req.getParameter("name").trim();
  29.             user.setId(userIService.getNewId());
  30.             user.setName(name);
  31.             userIService.saveOrUpdate(user);
  32.             List<User> list=userIService.getUsers();
  33.             req.setAttribute("userList", list);
  34.             return new ModelAndView("/WEB-INF/userList");
  35.         }else if(param.trim().equals("update")){
  36.             //修改的保存操作
  37.             Integer id=-1;
  38.             if(!req.getParameter("userId").trim().equals("")){
  39.                 id=Integer.parseInt(req.getParameter("userId").trim());
  40.             }
  41.             String name=req.getParameter("name").trim();
  42.             User user=userIService.getUserById(id);
  43.             user.setName(name);
  44.             userIService.saveOrUpdate(user);
  45.             List<User> list=userIService.getUsers();
  46.             req.setAttribute("userList", list);
  47.             return new ModelAndView("/WEB-INF/userList");
  48.         }else if(param.trim().equals("delete")){
  49.             //删除操作
  50.             Integer id=-1;
  51.             if(!req.getParameter("userId").trim().equals("")){
  52.                 id=Integer.parseInt(req.getParameter("userId").trim());
  53.             }
  54.             userIService.delete(id);
  55.             List<User> list=userIService.getUsers();
  56.             req.setAttribute("userList", list);
  57.             return new ModelAndView("/WEB-INF/userList");
  58.         }else if(param.trim().equals("detail")){
  59.             //详细用户页面
  60.             Integer id=-1;
  61.             if(!req.getParameter("userId").trim().equals("")){
  62.                 id=Integer.parseInt(req.getParameter("userId").trim());
  63.                 User user=userIService.getUserById(id);
  64.                 req.setAttribute("user", user);
  65.             }
  66.             return new ModelAndView("/WEB-INF/userDetail");
  67.         }else if(param.trim().equals("list")){
  68.             // list列表
  69.             List<User> list=userIService.getUsers();
  70.             req.setAttribute("userList", list);
  71.             return new ModelAndView("/WEB-INF/userList");
  72.         }
  73.         return new ModelAndView("fail");
  74.         //return forword("stu/studentList", context);  //同样也可以使用forword进行页面跳转
  75.         //使用Map向前台输出数据时，获取操作同Request一样，可以在前台使用${名字}来获取如下例，可以使用${message}获取
  76.         //Map<String,String> resultMap = new HashMap<String,String>();  
  77.         //resultMap.put("message", "欢迎来到首页111");  
  78.         //return new ModelAndView("index",resultMap);
  79.     }
  80.     public UserIService getUserIService() {
  81.         return userIService;
  82.     }
  83.     public void setUserIService(UserIService userIService) {
  84.         this.userIService = userIService;
  85.     }
  86. }

7、然后就是页面啦：

新增页面：

  1.  <body>
  2.           <a href="user.do?param=userList">用户列表</a>
  3.         <h3>新增用户</h3>
  4.         <form action="user.do" method="post">
  5.             <c:if test="${user!=null }">
  6.                 <input type="hidden" name="param" value="update" />
  7.             </c:if>
  8.             <c:if test="${user==null }">
  9.                 <input type="hidden" name="param" value="save" />
  10.             </c:if>
  11.             <input type="hidden" name="userId" value="${user.id }" />
  12.             用户名：<input type="text" name="name" value="${user.name }"  />
  13.             <input type="submit" value="提交" />
  14.         </form>
  15.   </body>

访问地址：http://localhost/user.do?param=add
修改页面也是此页面，访问地焉http://localhost/user.do?param=edit&userId=12

用户信息页面：

  1.  <body>
  2.           <a href="user.do?param=userList">用户列表</a>
  3.           <h3>用户详细信息：</h3>
  4.           <ul>
  5.               <li>ID:${user.id }</li>
  6.               <li>用户名:${user.name }</li>
  7.           </ul>
  8.   </body>

用户列表页面：

  1. <body>
  2.           <a href="user.do?param=add">新增用户</a>
  3.           <h3>用户列表：</h3>
  4.           <table>
  5.               <tr>
  6.                   <td>ID</td>
  7.                   <td>姓名</td>
  8.                   <td>操作</td>
  9.               </tr>
  10.               <c:forEach items="${userList }" var="user">
  11.                 <tr>
  12.                   <td>${user.id }</td>
  13.                   <td>${user.name }</td>
  14.                   <td><a href="user.do?param=edit&userId=${user.id }">修改</a></td>
  15.                   </tr>
  16.             </c:forEach>
  17.           </table>
  18.   </body>
