SpringMVC:restFul风格学习笔记

SpringMVC:restFul风格学习笔记

以前通过url传参需要：localhost:8080/t1?a=1&b=2
这样写url.
使用restFul风格：localhost:8080/t1/1/2
让你的url看起来相对简洁和相对安全

package com.huang.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

@Controller
public class RestFulTest01 {
//    @RequestMapping(value = "/t1/{a}/{b}",method= RequestMethod.GET)等价于下面这种
    @GetMapping("/t1/{a}/{b}")
    //@PathVariable设置restFul风格url传参
    public String test(@PathVariable int a,@PathVariable int b, Model model){
        int result = a+b;
        model.addAttribute("msg","@GetMapping结果为:"+result);
        return "Test";
    }

    @PostMapping("/t1/{a}/{b}")
    // @DeleteMapping
	// @PutMapping
    public String test2(@PathVariable int a,@PathVariable int b, Model model){
        int result = a+b;
        model.addAttribute("msg","@PostMapping结果为:"+result);
        //return "redirect:/index.jsp";重定向
        return "Test";
    }
}
