Microservices Zuul代理服务器在处理请求花费更多时间时引发内部服务器错误

当请求在服务中处理需要更多时间时，我收到此错误。但是Zuul返回内部服务器错误的响应

据我所知，使用zuul 2.0.0.RC2版本

，在服务没有响应、路由丢失等情况下，您可以设置/error端点以向用户提供自定义响应。 例如：

@Controller
public class CustomErrorController implements ErrorController {

    @RequestMapping(value = "/error", produces = "application/json")
    public @ResponseBody
    ResponseEntity error(HttpServletRequest request) {
        // consider putting these in a try catch
        Integer statusCode = (Integer)request.getAttribute("javax.servlet.error.status_code");
        Throwable exception = (Throwable)request.getAttribute("javax.servlet.error.exception");

        // maybe add some error logging here, e.g. original status code, exception, traceid, etc.

        // consider a better error to the user here
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("{'message':'some error happened', 'trace_id':'some-trace-id-here'}");
    }

    @Override
    public String getErrorPath() {
        return "/error";
    }
}
