SpringMvc01 第一个Springmvc应用

1. 引入jar包
       避免jar遗漏直接将Spring下的所有jar都进行引入另加一个commons-logging-1.1.1.jar:    
       commons-logging-1.1.1.jar
       spring-aop-4.1.6.RELEASE.jar
       spring-aspects-4.1.6.RELEASE.jar
       spring-beans-4.1.6.RELEASE.jar
       spring-context-4.1.6.RELEASE.jar
       spring-context-support-4.1.6.RELEASE.jar
       spring-core-4.1.6.RELEASE.jar    
       spring-expression-4.1.6.RELEASE.jar
       spring-instrument-4.1.6.RELEASE.jar
       spring-instrument-tomcat-4.1.6.RELEASE.jar
       spring-jdbc-4.1.6.RELEASE.jar
       spring-jms-4.1.6.RELEASE.jar
       spring-messaging-4.1.6.RELEASE.jar
       spring-orm-4.1.6.RELEASE.jar
       spring-oxm-4.1.6.RELEASE.jar
       spring-test-4.1.6.RELEASE.jar
       spring-tx-4.1.6.RELEASE.jar
       spring-web-4.1.6.RELEASE.jar
       spring-webmvc-4.1.6.RELEASE.jar
       spring-webmvc-portlet-4.1.6.RELEASE.jar
       spring-websocket-4.1.6.RELEASE.jar
       
2. 配置web.xml
   在web.xml中配置Springmvc的前置控制器，并在参数中指定加载的Spring配置文件luji

   
   
     SpringMvc
     
     
     	springmvc
     	org.springframework.web.servlet.DispatcherServlet
     	
     		contextConfigLocation
     		classpath:cfg/spring.xml
     	
     	1
     
     
     	springmvc
     	/
     
     
     
       index.html
       index.htm
       index.jsp
       default.html
       default.htm
       default.jsp
     
   

3. 编写controller类
   通过实现Controller接口实现控制器功能

   package com.xiaohui.controller;
   
   import javax.servlet.http.HttpServletRequest;
   import javax.servlet.http.HttpServletResponse;
   
   import org.springframework.web.servlet.ModelAndView;
   import org.springframework.web.servlet.mvc.Controller;
   
   public class HelloController  implements Controller{
   
   	@Override
   	public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
   		
   		ModelAndView modelAndView = new ModelAndView();
   		//添加数据模型
   		modelAndView.addObject("msg", "hello springmvc");
   		//设置逻辑试图名，视图解析器会根据改名字解析到具体的视图页面
   		modelAndView.setViewName("/WEB-INF/jsp/hello.jsp");
   		return modelAndView;
   	}
   }

4. 配置springmvc.xml
   
   注册控制器bean + 处理映射器HandlerMapping + 处理器适配器HandlerAdapter + 视图渲染器

5. jsp页面
   
   路径：/WEB-INF/jsp/hello.jsp

   <%@ page language="java" contentType="text/html; charset=UTF-8"
       pageEncoding="UTF-8"%>
   
   
   
   
   
   
   
   ${msg}
   
   

6. 项目结构
   
7. 测试路径及结果
