英文:
Method 'GET' is not supported
问题
当我发送HTTP POST请求时，屏幕上出现了这个消息。我该如何解决这个问题？我没有使用任何GET注解或请求。
HTPP 请求：http://localhost:9000/user/register?username=a&password=1
控制台错误
> 无法加载资源：服务器响应状态为405（方法不允许）
JavaScript
<script>document.getElementById("signupbtn").addEventListener("click",function(){const username = document.getElementById("username").value;const password = document.getElementById("password").value;const xhr = new XMLHttpRequest();xhr.open("POST","http://localhost:9000/user/register?username="+username+"&password="+password);xhr.send();})</script>
控制器
@PostMapping("/register")ResponseEntity<String> addUser(@RequestParam("username") String username,@RequestParam("password") String password) {userService.addUser(username, password);return ResponseEntity.ok("用户已成功添加");}
服务
public void addUser(String username,String password){userRepository.save(new User(username,password));}
英文:
When I make HTTP POST request, I got this message on my screen. How can I solve this problem? I don't use any GET annotation or request.

问题出在当我发送请求时。这是一个GET请求而不是POST。我将PostMapping更改为GetMapping问题得到解决。我认为关于POST和GET映射存在误解。
英文:
The problem is when i send to request. This is a GET request not POST . I changed the PostMapping To GetMapping problem is solved. I think there is missunderstanding about POST and GET mapping

你的代码没有问题，除非你的应用安全配置中有限制，比如（allowedMethods）。
英文:
there is nothing wrong with your code , it should work unless you do have restriction in your app security config like (allowedMethods )
