为什么我在通过HTTPS调用DELETE时遇到IllegalArgumentException但在使用HTTP时没有，而在通过HTTPS调用GET时没有？

对此问题的任何想法都将不胜感激。

我正在使用Jersey 2.24.1客户端访问Play Framework服务器的REST API。通常我可以访问大多数API端点（GET，POST，PUT）（或看似如此）：

Response response = ClientBuilder.newClient().target("https://api.myserver.com")
                                .path("/getEndpointPath")
                                .request()
                                .header(HttpHeaders.AUTHORIZATION, "encoded auth string")
                                .get();

但是，在使用HTTPS时调用DELETE方法会引发异常，但如果将url更改为使用HTTP，则不会异常失败：

Response response = ClientBuilder.newClient().target("https://api.myserver.com")
                                .path("/deleteEndpointPath")
                                .request()
                                .header(HttpHeaders.AUTHORIZATION, "encoded auth string")
                                .delete();

堆栈跟踪：

此外，我可以使用Postman 通过HTTPS访问这些端点，因此看起来端点并未完全断开。

知道如何发生这种情况吗？

我遇到了这个问题，这是一个简单的错误，将其留在这里以防其他人受益。 在下面的代码中，我省略了@PathVariable（value =“ id”）。现在，它包含以下作品。

@DeleteMapping("/deletePosition/{id}")
public ResponseEntity<?> deletePositionById(@PathVariable (value = "id") Long positionId) {
    return positionService.deletePositionById(positionId);
    
}
