FeignClient调试404 feign FeignException status 404 reading

先说一下源码
调用Feign服务的时候执行的核心代码如下

package feign;.......//省略import/** * Submits HTTP {@link Request requests}. Implementations are expected to be thread-safe. */public interface Client {  /**   * Executes a request against its {@link Request#url() url} and returns a response.   *   * @param request safe to replay.   * @param options options to apply to this request.   * @return connected response, {@link Response.Body} is absent or unread.   * @throws IOException on a network error connecting to {@link Request#url()}.   */  Response execute(Request request, Options options) throws IOException;  public static class Default implements Client {    private final SSLSocketFactory sslContextFactory;    private final HostnameVerifier hostnameVerifier;    /**     * Null parameters imply platform defaults.     */    public Default(SSLSocketFactory sslContextFactory, HostnameVerifier hostnameVerifier) {      this.sslContextFactory = sslContextFactory;      this.hostnameVerifier = hostnameVerifier;    }    @Override    public Response execute(Request request, Options options) throws IOException {      HttpURLConnection connection = convertAndSend(request, options);      return convertResponse(connection).toBuilder().request(request).build();    }

feign.client.Default#excute 方法会记录请求的信息。
到查理debug看看发出去的请求能不能访问

feign:   hystrix:    enabled: true

如果断融器打开会报错如下
