HelloController.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@Autowired

@RequestMapping(value = "/user",method = RequestMethod.GET)
public String getUser()

index.html
<!DOCTYPE html>

<meta charset="UTF-8">
<title>Title</title>

<body>
<h1>在下济北公游坦之</h1>
<form action="/user" method="get">
<input value="REST-GET 提交" type="submit">
</form>
<form action="/user" method="post">
<input value="REST-POST 提交" type="submit">
</form>
<form action="/user" method="put">
<input value="REST-PUT 提交" type="submit">

<form action="/user" method="delete">

效果

分析：PUT和DELETE显示的全是Get，原因是下面这两个都会默认当成Get方式
编辑
处理Put和Delete
开启hiddenmethod功能
spring:
mvc:
hiddenmethod:
filter:
enabled: true
编辑
修改上面代码如下（此处delete、put可以用大写或者小写，最终会在底层转化成大写）
<form action="/user" method="post">
<input name="_method" type="hidden" value="put">
<input value="REST-PUT 提交" type="submit">
</form>
<form action="/user" method="post">
<input name="_method" type="hidden" value="delete">
<input value="REST-DELETE 提交" type="submit">
</form>

RestMapping简写
@RequestMapping(value = "/user",method = RequestMethod.GET) === @GetMapping("/user")
红色的那一行就等于蓝色的那一行
编辑
编辑 其他同理
****编辑
自定义_method
编辑
methodFilter.setMethodParam("_ytz");括号里面写自己想改的
package com.you.boot.boot.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.HiddenHttpMethodFilter;
@Configuration(proxyBeanMethods = false)
public class WebConfig {
@Bean
public HiddenHttpMethodFilter hiddenHttpMethodFilter()
{
HiddenHttpMethodFilter methodFilter = new HiddenHttpMethodFilter();
methodFilter.setMethodParam("_ytz");
return methodFilter;
}
}
