       spring-context
            
      
       ${spring.version}
          
         
           
      
       org.springframework
            
      
       spring-test
            
      
       ${spring.version}
          
         
           
      
       org.springframework
            
      
       spring-beans
            
      
       ${spring.version}
          
         
           
      
       org.springframework
            
      
       spring-webmvc
            
      
       ${spring.version}
          
         
           
      
       org.springframework
            
      
       spring-jdbc
            
      
       ${spring.version}
          
         
           
      
       org.springframework
            
      
       spring-aspects
            
      
       ${spring.version}
          
       
      
        
     
      springMVC-day01
         
     
            
              
                 
        
         maven-clean-plugin

         maven-resources-plugin
                  
        
         3.0.2
                
               
                 
        
         maven-compiler-plugin
                  
        
         3.8.0
                
               
                 
        
         maven-surefire-plugin
                  
        
         2.22.1
                
               
                 
        
         maven-war-plugin
                  
        
         3.2.2
                
               
                 
        
         maven-install-plugin
                  
        
         2.5.2

准备一个controller

package com.tianqicode.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class Hello {
       @RequestMapping(path = "/hello")    public String helloSpringMVC() {
           System.out.println("Hello,SpringMVC!");        return "hello";    }}

配置web.xml

     
    
     Archetype Created Web Application
        
        
         
     
      dispatcherServlet
         
     
      org.springframework.web.servlet.DispatcherServlet
         
         
           
      
       contextConfigLocation
            
      
       classpath:springmvc.xml
          
         
     
      1
       
      
        
     
      dispatcherServlet
         
     
      /
       
    
   

配置springmvc.xml

准备两个前端页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
