如何在Spring MVC中的@controllerAdvice或@RestControllerAdvice中找到控制器名称？
问题内容：
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(NoHandlerFoundException.class)
public ResponseEntity<Error> handle(NoHandlerFoundException ex){
String message = "HTTP " + ex.getHttpMethod() + " for " + ex.getRequestURL() + " is not supported.";
Error error = new Error(HttpStatus.NOT_FOUND.value(), message);
return new ResponseEntity<Error>(error, HttpStatus.NOT_FOUND);
}
}
- 我正在将@ControllerAdvice与@ExceptionHandler一起使用。
- 我需要获取异常的控制器类名称和程序包名称或handle方法内的类对象
问题答案：
这应该工作
@ControllerAdvice
class AdviceA {
@ExceptionHandler({SomeException.class})
public ResponseEntity<String> handleSomeException(SomeException pe, HandlerMethod handlerMethod) {
Class controllerClass = handlerMethod.getMethod().getDeclaringClass();
//controllerClass.toString will give you fully qualified name
return new ResponseEntity<>("SomeString", HttpStatus.BAD_REQUEST);
}
