Java 每个命令的Hystrix类？

我的应用程序有一组可配置的运行时外部端点可供调用：

/foo
/bar

和用于使用apache HttpClient进行http调用

我想在这里使用Hystrix包装HttpClient，但我想为每个端点分离断路器，这样，如果一个端点出现故障，就不会影响另一个端点

我可以通过上两门课来做到这一点：

FooCommand extends HystrixCommand<...> {
}

BarCommand extends HystrixCommand<...> {
}

---

如果1失败，2仍将被单独执行和处理

您可以在构造函数中设置命令键。像这样的

public class HttpCommand extends HystrixCommand<HttpResponse> {

  private final HttpClient httpClient;
  private final HttpRequestBase request;

  public HttpCommand(String commandKey, HttpClient httpClient, HttpRequestBase request) {
    super(Setter.withGroupKey(HystrixCommandGroupKey.Factory.asKey("HttpGroup"))
        .andCommandKey(HystrixCommandKey.Factory.asKey(commandKey)));
    this.httpClient = httpClient;
    this.request = request;
  }

  @Override
  protected HttpResponse run() throws Exception {
    return httpClient.execute(request);
  }

}

啊，你可能是对的。给出了一个解决类似问题的示例。我会重新测试，然后再给你回复

new MyHystrixHttpClient("/foo").execute(); // (1)
new MyHystrixHttpClient("/bar").execute(); // (2)

public class HttpCommand extends HystrixCommand<HttpResponse> {

  private final HttpClient httpClient;
  private final HttpRequestBase request;

  public HttpCommand(String commandKey, HttpClient httpClient, HttpRequestBase request) {
    super(Setter.withGroupKey(HystrixCommandGroupKey.Factory.asKey("HttpGroup"))
        .andCommandKey(HystrixCommandKey.Factory.asKey(commandKey)));
    this.httpClient = httpClient;
    this.request = request;
  }

  @Override
  protected HttpResponse run() throws Exception {
    return httpClient.execute(request);
  }

}
