Spring - 405 Http method DELETE is not supported by this URL
提问by Sasanka Panguluri
Well I have a strange problem with executing a "DELETE" HTTP request in Spring.
好吧，我在 Spring 中执行“DELETE”HTTP 请求时遇到了一个奇怪的问题。
I have a controller method which I have mapped a DELETE request to:
我有一个控制器方法，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");
}
The controller is mapped using @RequestMapping("/authorization_servers");When I send a request through my DEV Http Client, I am getting the response : 405 Http method DELETE is not supported by this URL.
@RequestMapping("/authorization_servers");当我通过我的 DEV Http 客户端发送请求时，控制器被映射，我得到了响应：405 Http method DELETE is not supported by this URL。
The request looks like this:
请求如下所示：
DELETE localhost:8080/authorization_servers/asxas
Headers:
Authorization: "test:<stuff>"
If someone can look into this and help me, I would be grateful
如果有人可以调查并帮助我，我将不胜感激

This will work:
这将起作用：
@RequestMapping(value = "/{authorizationUrl}", method = DELETE)
public @ResponseBody 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);
}
You were missing @ResponseBody. Your method was actually getting called; it was what happened after that that was producing the error code.
你错过了@ResponseBody。你的方法实际上被调用了；之后发生的事情产生了错误代码。

Your annotation should look like this:
您的注释应如下所示：
@RequestMapping(value = "/{authorizationUrl}",method=RequestMethod.DELETE)
I don't know where you got that DELETE variable from. :-)
我不知道你从哪里得到那个 DELETE 变量。:-)

If the @RequestMappingpattern doesn't match or is invalid, it results in a 404 not found. However, if it happens to match another mapping with a different method (ex. GET), it results in this 405 Http method DELETE is not supported.
如果@RequestMapping模式不匹配或无效，则会导致 404 not found。但是，如果它碰巧用不同的方法（例如 GET）匹配另一个映射，则会导致此405 Http method DELETE is not supported.
My issue was just like this one, except my requestMapping was the cause. It was this:
我的问题就像这个一样，除了我的 requestMapping 是原因。原来是这样：
@RequestMapping(value = { "/thing/{id:\d+" }, method = { RequestMethod.DELETE })
Do you see it? The inner closing brace is missing, it should be: { "/thing/{id:\\d+}" }The \\d+is a regular expression to match 1 or more numeric digits. The braces delimit the parameter in the path for use with @PathVariable.
你看到了吗？缺少内部右大括号，应该是：{ "/thing/{id:\\d+}" }The \\d+is a regular expression to match 1 or more numeric numbers。大括号分隔路径中的参数以用于@PathVariable.
Since it's invalid it can't match my DELETE request: http://example.com/thing/33which would have resulted in a 404 not found error, however, I had another mapping for GET:
由于它无效，它无法匹配我的 DELETE 请求：http: //example.com/thing/33这会导致 404 not found 错误，但是，我有另一个 GET 映射：
@RequestMapping(value = { "/thing/{id:\d+}" }, method = { RequestMethod.GET })
Since the brace pattern is correct, but it's not a method DELETE, then it gave a error 405 method not supported.
由于大括号模式是正确的，但它不是 DELETE 方法，因此它给出了错误 405 方法不支持。
Hope this helps you!
希望这对你有帮助！

also make sure you're calling it with "Content-Type" header="text/html". If not, then change it or specify it in the requestMapping. If it doesn't match, you get the same 405.
还要确保你用"Content-Type" header="text/html". 如果没有，则更改它或在requestMapping. 如果不匹配，您会得到相同的 405。
Hope this helps someone.

I needed to return ResponseEntity<Void>(with custom response status) instead of setting custom response status on HttpServletResponse(from endpoint method param).
我需要返回ResponseEntity<Void>（使用自定义响应状态）而不是设置自定义响应状态HttpServletResponse（来自端点方法参数）。
