Spring boot 2-如何将所有响应头发送到客户端？

@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(Exception.class)
    public ResponseEntity<Object> handleException(Exception ex, WebRequest request) {
        HttpHeaders headers = new HttpHeaders();
        // 设置响应头
        headers.set("Custom-Header", "Value");
        
        // 构建响应体
        ErrorResponse errorResponse = new ErrorResponse("Error message");
        
        return new ResponseEntity<>(errorResponse, headers, HttpStatus.INTERNAL_SERVER_ERROR);
    }
}
