如何在Jersey-Client Java中实现重试机制 [英] How to implement a retry mechanism in jersey-client java

问题描述

我正在使用jersey-client进行一些http rest api调用.现在，我想重试失败请求.假设返回错误代码不是200，那么我想重试几次.如何使用Jersey客户端

I am doing some http rest api calls using jersey-client. Now I want to do a retry for a failure request. Say if the return error code is not 200 then I want to retry it again for a few times. How can do it using Jersey client

推荐答案

要在任何情况下实施重试，请查看故障保护:

For implementing retries in any situation, check out Failsafe:

RetryPolicy retryPolicy = new RetryPolicy()
  .retryIf((ClientResponse response) -> response.getStatus() != 200)
  .withDelay(1, TimeUnit.SECONDS)
  .withMaxRetries(3);

Failsafe.with(retryPolicy).get(() -> webResource.post(ClientResponse.class, input));

如果响应状态！= 200，此示例将重试，最多3次，重试之间间隔1秒.

This example retries if the response status != 200, up to 3 times, with a 1 second delay between retries.
