考虑以下代码：
MyRest控制器：

@RestController
public class MyResponseEntity {

    @GetMapping("/response")
    public StreamingResponseBody getResponseEntity() {
        return out -> {
            throw new RuntimeException("I throw a RuntimeException");
        };
    }
}

myrestcontrolleradvice公司

@RestControllerAdvice
public class MyRestControllerAdvice extends ResponseEntityExceptionHandler {

    @ExceptionHandler(value = {RuntimeException.class})
    private ResponseEntity<Object> handleRestRuntimeException(final RuntimeException ex, final WebRequest request) {
        return handleExceptionInternal(ex, new ApiError(INTERNAL_SERVER_ERROR), new HttpHeaders(), INTERNAL_SERVER_ERROR, request);
    }
}

API错误

public class ApiError {

    private HttpStatus status;

    public ApiError(HttpStatus status) {
        this.status = status;
    }
// getter, setter

答复如下：

{
    "status": "INTERNAL_SERVER_ERROR"
}{
    "timestamp": "2021-04-23T13:51:41.438+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "I throw a RuntimeException",
    "path": "/response"
}

我希望只返回第一个json对象：{“status”：“internal\u server\u error”}
我在ResonSentityExceptionHandler spring的类中发现了以下内容，但我不知道这是否会影响响应主体：

if (HttpStatus.INTERNAL_SERVER_ERROR.equals(status)) {
    request.setAttribute(WebUtils.ERROR_EXCEPTION_ATTRIBUTE, ex, WebRequest.SCOPE_REQUEST);
}

有人知道为什么这段代码返回两个json对象吗？
