29.1 java代码如下:

package com.eduask.controller;
 import org.springframework.stereotype.Controller;
 import org.springframework.web.bind.annotation.RequestMapping;
  @Controller
 public class Demo2 {
    @RequestMapping("/testRedirect")
    public String getRedirect(){
       return "redirect:/demo2";
    }
  //重定向映射路径
 @RequestMapping("/demo2")
 public String getRedirect1(){
    return "demo2";
 }
 }

29.2 springmvc-servlet.xml配置文件:

<!-- 配置适配解析器 -->
 <context:component-scan base-package="com.eduask"/>
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="prefix" value="/WEB-INF/view/"></property>
 <property name="suffix" value=".jsp"></property>
 </bean>
 <mvc:view-controller path="/demo2" view-name="demo2"/>
 <!--  启动mvc-->
 <mvc:default-servlet-handler/>
 <mvc:annotation-driven/>

29.程序运行如下:

30 SpringMvc中的List集合
 30.1  java代码如下:
 @Controller
 public class Demo3 {
 @ResponseBody
 @RequestMapping("/demo3")
 public List<User> getUser(){
 List<User> user=new ArrayList<User>();
 User u=new User("tom", "123456", 5000, 20);
 user.add(u);
 System.out.println(u);
 return user;
 }

30.2 springmvc-servlet配置如下：

<!-- 配置适配解析器 -->

<context:component-scan base-package="com.eduask"/>
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="prefix" value="/WEB-INF/view/"></property>
 <property name="suffix" value=".jsp"></property>
 </bean>
 <mvc:view-controller path="/demo3" view-name="/user/list"/>
 <!--启动mvc-->
 <mvc:default-servlet-handler/>
 <mvc:annotation-driven/>
