java - Spring - 此 URL 不支持 405 Http 方法 DELETE

Question

嗯，我在 Spring 中执行“DELETE”HTTP 请求时遇到了一个奇怪的问题。

我有一个 Controller 方法，我已将 DELETE 请求映射到:

    @RequestMapping(value = "/{authorizationUrl}",method=DELETE)
    public void deleteAuthorizationServer(
            @RequestHeader(value="Authorization") String authorization,
            @PathVariable("authorizationUrl") String authorizationUrl)
            throws  IOException {

        System.out.println("TEST");

    }

使用 @RequestMapping("/authorization_servers"); 映射 Controller 当我通过我的 DEV Http 客户端发送请求时，我收到了响应:405 Http method DELETE is not supported by this URL.

请求如下所示:

 DELETE    localhost:8080/authorization_servers/asxas

  Headers:
  Authorization: "test:<stuff>"

如果有人可以调查此问题并帮助我，我将不胜感激

这将起作用:

@RequestMapping(value = "/{authorizationUrl}", method = DELETE)
@ResponseBody
public void deleteAuthorizationServer(
    @RequestHeader(value="Authorization") String authorization,
    @PathVariable("authorizationUrl") String authorizationUrl
){
    System.out.printf("Testing: You tried to delete %s using %s\n", authorizationUrl, authorization);
}

你错过了@ResponseBody。您的方法实际上被调用了；正是在那之后发生的事情才产生了错误代码。
