简单应用

Controller层

package com.harris.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class RestfulController {

    @RequestMapping(value = "/add/{a}/{b}",method = RequestMethod.GET)
    public  String test(@PathVariable int a,@PathVariable int b, Model model){
        int res= a+b;
        model.addAttribute("msg","结果为:"+res);
        return "hello";
    }
}

通过对要传入的变量添加注解@PathVariable 使得可以通过url以/的形式传参。
