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 }
