springMVC RequestMapping

1 加的地方

1.可以加在类上 用于模块

2.可以加在方法上 用于路径

 

package com.cj.mvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("test")
public class TestController {
    @RequestMapping("test1")
    public String test1(){
        return "test1";
    }
}

 

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>首页</h1>
<a th:href="@{/test/test1}">测试1</a>
</body>
</html>

 

2 value属性

可以匹配多个

package com.cj.mvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("test")
public class TestController {
    @RequestMapping(value = {"test1","test2"})
    public String test1(){
        return "test1";
    }
}

3 method

@RequestMapping(value = {"test1","test2"},method = {RequestMethod.GET})

4 派生

@GetMapping("test3")
@PostMapping
@DeleteMapping

 

5 Params

@GetMapping(value = "test3",params = {"username"})
public String test3(){
    return "test3";
}
<a th:href="@{/test/test3(username='admin')}">测试3</a>

 

6 ant风格

？匹配任意单个字符

* 匹配任意的0个或者多个字符

** 匹配任意的一层或多层目录

7  占位符

@GetMapping("/test5/{id}")
public String test5(@PathVariable("id") Integer id){
    return "test5";
}
