ContainerResponseContext错误的状态码

Question

我正在Wildlfy Server 8.1.0.Final上部署WS，并且遇到以下问题。

我正在使用普罗米修斯作为指标，并且尝试通过ContainerResponseFilter获取请求的http响应代码。问题是我为某些请求获取了错误的状态代码。

例如，我的WS使用/ ping端点进行健康检查，它以201而不是200进行响应。当还有许多其他请求以201进行响应时，就会发生这种情况。

ContainerResponseFilter可能无法每秒处理大量请求并混淆响应者代码。

 @Provider
public class CountAndLatencyMetrics implements ContainerResponseFilter, ContainerRequestFilter {

 @Context
ResourceInfo resourceInfo;

@Context
SecurityContext securityContext;

private static final Counter httpRequestsTotal = Counter
        .build("http_requests_total", "Total number of HTTP requests")
        .labelNames("request", "user", "responseCode")
        .register();

private static final Histogram httpRequestsLatency = Histogram
        .build("http_requests_latency", "Total latency of HTTP requests")
        .labelNames("request", "user")
        .register();

private Histogram.Timer timer;
private String userName;
private String javaMethodName;
private String endpointName;
private String request;
private int responseCode;

@Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) {
    timer.observeDuration();
    responseCode = responseContext.getStatus();
    httpRequestsTotal.labels(request, userName, String.valueOf(responseCode)).inc();

}

@Override
public void filter(ContainerRequestContext requestContext) {
    userName = securityContext.getUserPrincipal().getName();
    javaMethodName = resourceInfo.getResourceMethod().getName();
    endpointName = resourceInfo.getResourceMethod().getAnnotation(Path.class).value();
    request = javaMethodName + " - " + endpointName;
    timer = httpRequestsLatency.labels(request, userName).startTimer();

}
}
