1.使用springmvc框架

1）编写controller

package com.company.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;/** * @RestController */@Controller@RequestMapping("demo")public class DemoController {    @RequestMapping("sayHello")    @ResponseBody    public String sayHello(String name){        return "Hello,"+name+"!";    }}

2）配置文件spring-mvc

3）web.xml修改：字符过滤器+Springmvc核心分发DispatcherServlet

    
        
         
             
      
       encodingFilter
              
      
       org.springframework.web.filter.CharacterEncodingFilter
              
                  
       
        encoding
                   
       
        UTF-8
               
              
                  
       
        forceEncoding
                   
       
        true
               
          
         
             
      
       encodingFilter
              
      
       /*
          
         
             
      
       spring mvc servlet
              
      
       DispatcherServlet
              
      
       org.springframework.web.servlet.DispatcherServlet
              
                  
       
        contextConfigLocation
                   
       
                        classpath:spring*.xml            
               
              
      
       1
          
         
             
      
       DispatcherServlet
              
      
       *.do
          
     
    

2.验收

运行demo-web, 输入http://localhost:8080/demo-web/demo/sayHello.do?name=wsy。运行结果如下：
