先看程式碼，程式碼如下：

package com.yoni.springmvc.handlers;  
  
import org.springframework.stereotype.Controller;  
import org.springframework.web.bind.annotation.RequestMapping;  
  
@Controller  
public class HelloWorld {  
      
    @RequestMapping("/helloworld/{id}")  
    public String hello(@PathVariable("id")  int id){  
        System.out.println("Hello World:" + id);
        return "success";  
    }  
      
}  
 

<a href= "helloworld/221" >Hello World</a>

這是提交出去請求，將會在控制檯顯示

Hello World：221
