springboot请求处理rest映射

前端的form标签只能提交get和post请求，如果想提交delete和put请求，则用以下方法

<form action="/user" method="post">
    <input name="_method" value="DELETE" type="hidden">
    <input type="submit" value="提交">
</form>
<form action="/user" method="post">
    <input name="_method" value="PUT" type="hidden">
    <input type="submit" value="提交">
</form>

需修改配置文件

spring:
  mvc:
    hiddenmethod:
      filter:
        enabled: true

controller方法（@RestController标注类）：

 @RequestMapping(value = "/user",method = RequestMethod.DELETE)
    public String string(){
        return "delete请求";
    }
    @RequestMapping(value = "/user",method = RequestMethod.PUT)
    public String string2(){
        return "put请求";
    }

此时可以发起DELETE和PUT请求：
