Spring Boot:如何在出现错误时定制JSON响应(使用ControllerAdvice)

@ControllerAdvice
public class GlobalExceptionHandler {
    // 异常处理方法
}

@ControllerAdvice
public class GlobalExceptionHandler {
    @ExceptionHandler(Exception.class)
    public ResponseEntity<ErrorResponse> handleException(Exception ex) {
        // 处理异常并返回自定义的错误响应
    }
}

@ControllerAdvice
public class GlobalExceptionHandler {
    @ExceptionHandler(Exception.class)
    public ResponseEntity<ErrorResponse> handleException(Exception ex) {
        ErrorResponse errorResponse = new ErrorResponse();
        errorResponse.setMessage("自定义错误信息");
        errorResponse.setCode(HttpStatus.INTERNAL_SERVER_ERROR.value());
        // 其他自定义字段
        return new ResponseEntity<>(errorResponse, HttpStatus.INTERNAL_SERVER_ERROR);
    }
}

public class ErrorResponse {
    private String message;
    private int code;
    // 其他字段的getter和setter方法
}
