这篇是接着上篇Spring单元测试写的。
一.修改web.xml,配置SpringMVC的前端控制器
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 5 id="ticc_web" version="3.0"> 6 <servlet> 7 <servlet-name>dispatcher</servlet-name> 8 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 9 <init-param> 10 <param-name>contextConfigLocation</param-name> 11 <param-value>classpath:spring.xml</param-value> 12 </init-param> 13 <load-on-startup>1</load-on-startup> 14 </servlet> 15 <servlet-mapping> 16 <servlet-name>dispatcher</servlet-name> 17 <url-pattern>/</url-pattern> 18 </servlet-mapping> 19 </web-app>
2.修改spring.xml，配置SpringMVC的视图解析器
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" xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 7 http://www.springframework.org/schema/context 8 http://www.springframework.org/schema/context/spring-context-4.0.xsd 9 http://www.springframework.org/schema/tx 10 http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 11 http://www.springframework.org/schema/aop 12 http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 13 "> 14 <!-- 自动扫描dao和service包(自动注入) --> 15 <context:component-scan base-package="com.youms.ssh.webService" /> 16 17 <!-- 配置视图解析器: 负责将视图名解析成真正的视图对象(比如jsp) --> 18 <bean 19 class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 20 <property name="prefix" value="/WEB-INF/"></property> 21 <property name="suffix" value=".jsp"></property> 22 </bean> 23 </beans>
3.在WEB-INF下添加页面NewFile.jsp
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 </head>
9 <body>
10 <h1>Hello Spring!</h1>
11
12 <h2>${test1}</h2>
13 <h2>${test2}</h2>
14 </body>
15 </html>
4.测试
1 package com.youms.ssh.webService.controller;
2
3 import javax.servlet.http.HttpServletRequest;
4 import javax.servlet.http.HttpServletResponse;
5
6 import org.springframework.beans.factory.annotation.Autowired;
7 import org.springframework.stereotype.Controller;
8 import org.springframework.web.bind.annotation.RequestMapping;
9 import org.springframework.web.bind.annotation.RequestMethod;
10 import org.springframework.web.servlet.ModelAndView;
11
12 import com.youms.ssh.webService.service.UserService;
13
14 @Controller
15 @RequestMapping("/test")
16 public class Test {
17 @Autowired
18 private UserService userService;
19
20 /**
21 * 测试普通的方法
22 * 此方法能接收到通过方法testRedirect1()重定向传来的参数
23 * 此方法能将通过方法testForward1()转发过来的参数传给页面
24 * @return
25 */
26 @RequestMapping(value="/testView",method=RequestMethod.GET)
27 public String testView(HttpServletRequest req,String test2){
28 System.out.println("进入TestAction");
29 System.out.println(test2+"=======================");
30 userService.test();
31 return "testView/NewFile";
32 }
33
34 /**
35 * 测试使用ModelAndView传参
36 * @param res
37 * @return
38 */
39 @RequestMapping(value="/testModel",method=RequestMethod.GET)
40 public ModelAndView testModel(HttpServletResponse res){
41 //与页面编码保持一致则不会乱码
42 res.setCharacterEncoding("utf-8");
43 ModelAndView mav = new ModelAndView("testView/NewFile");
44 mav.addObject("test1","测试1!");
45 return mav;
46 }
47
48 /**
49 * 测试使用ModelAndView重定向
50 * @param res
51 * @return
52 */
53 @RequestMapping(value="/testRedirect1",method=RequestMethod.GET)
54 public ModelAndView testRedirect1(HttpServletResponse res){
55 //与页面编码保持一致则不会乱码
56 res.setCharacterEncoding("utf-8");
57 ModelAndView mav = new ModelAndView("redirect:/test/testView");
58 mav.addObject("test2","测试2!");
59 return mav;
60 }
61
62 /**
63 * 测试使用字符串重定向
64 * @param res
65 * @return
66 */
67 @RequestMapping(value="/testRedirect2",method=RequestMethod.GET)
68 public String testRedirect2(HttpServletResponse res){
69 return "redirect:/test/testView";
70 }
71
72 /**
73 * 测试使用ModelAndView转发
74 * @param res
75 * @return
76 */
77 @RequestMapping(value="/testForward1",method=RequestMethod.GET)
78 public ModelAndView testForward1(HttpServletResponse res){
79 //与页面编码保持一致则不会乱码
80 res.setCharacterEncoding("utf-8");
81 ModelAndView mav = new ModelAndView("forward:/test/testView");
82 mav.addObject("test2","测试2!");
83 return mav;
84 }
85
86 /**
87 * 测试使用字符串转发
88 * @param res
89 * @return
90 */
91 @RequestMapping(value="/testForward2",method=RequestMethod.GET)
92 public String testForward2(HttpServletResponse res){
93 return "forward:/test/testView";
94 }
95 }
