在控制器建议中，您可以为自定义异常提供如下处理程序。

@ControllerAdvice
public class CustomGlobalExceptionHandler {
    @ExceptionHandler(CustomException.class)
    public final ResponseEntity<ApiResponseDTO> manageException(CustomException ex) {
        log.error("Error in CustomException: {}", ex.getMessage(), ex);
        ApiResponseDTO error = ApiResponseDTO.builder()
                .message(ex.getMessage())
                .result(0)
                .build();
        return new ResponseEntity<>(error, HttpStatus.NOT_FOUND);
    }

    @ExceptionHandler(CustomException1.class)
    public final ResponseEntity<ApiResponseDTO> manageException1(CustomException1 ex) {
        log.error("Error in CustomException1: {}", ex.getMessage(), ex);
        ApiResponseDTO error = ApiResponseDTO.builder()
                .message(ex.getMessage())
                .result(0)
                .build();
        return new ResponseEntity<>(error, HttpStatus.NOT_FOUND);
    }

    @ExceptionHandler(Exception.class)
    public final ResponseEntity<ApiResponseDTO> manageException1(Exception ex) {
        log.error("Error in Common Exception Handler: {}", ex.getMessage(), ex);
        StackTraceElement[] ste = ex.getStackTrace();
        String className=ste[ste.length - 1].getClassName();
        System.out.println(className);
        if(className.equalsIgnoreCase("com.a")){
            System.out.println("Do A related stuff");
        }else{
            System.out.println("Do B related stuff");
        }
        ApiResponseDTO error = ApiResponseDTO.builder()
                .message(ex.getMessage())
                .result(0)
                .build();
        return new ResponseEntity<>(error, HttpStatus.NOT_FOUND);
    }

}

正如在最后一块中提到的，您可以从抛出异常的位置获取类名，并利用该名称分支出您的内容。
