Restful风格路径代码编写

作者：互联网

常规路径get提交

前端页面

<%--
  Created by IntelliJ IDEA.
  User: wsh
  Date: 2022/5/31
  Time: 9:08
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<form action="/spring_mvc02_war_exploded/add" method="get">
<input type="text" name="a">
<br/>
<input type="text" name="b">
<br/>
<input type="submit">
</form>
</body>

</html>

浏览器传递地址

controller后端处理代码

 @GetMapping("/add")
    public String test2( String a,String b,Model model){
        String res=a+b;
        model.addAttribute("msg","结果为："+res);

        return "hello";
    }

注意：springMVC的Controller类里面Mapping映射下所有方法里的参数都可匹配浏览器地址传递的参数

 

 

用Restful方式传递参数，可在需要传递的参数前加

@PathVariable
注解

可用

@RequestMapping

不同的延申注解接收相同地址的不同提交方式的数据

如下

post提交页面

</head>
<body>
<form action="/spring_mvc02_war_exploded/add/2/3" method="post">
  
  <input type="submit">
</form>
</body>
</html>

/2/3为restful传输方式的数据用url传递

后端Controller类代码：

@Controller
public class restfulController {
    @RequestMapping(value = "/add/{a}/{b}",method = {RequestMethod.POST})
    public String test(@PathVariable int a, @PathVariable int b, Model model){
        model.addAttribute("msg","结果为："+a+b);

        return "hello";
    }

最后hello.jsp显示页面，补充
