我遇到了一个“nohttpresponseexception”异常，看起来好像我从连接池中选择了一个服务器单方面关闭的链接，之后我又重复了一遍，但还是会返回这个异常，我觉得如果我在重试时能够从连接池中选择一个新的连接，可以解决这个问题，所以我想知道如何在jestclient连接池中重试时选择一个新链接。

@Data
@Configuration
public class JestClientConfig {
    private String url;
    private Boolean multiThreaded;
    private Integer maxTotalConnectionPerRoute;
    private Integer maxTotalConnection;
    private Integer connTimeout;
    private Integer readTimeout;
    private Integer connectionIdleTime;
    @Bean
    public JestClient getJestClient() {
        String[] uriArr = url.split(",");
        Set<String> serverUris = new LinkedHashSet<String>(Arrays.asList(uriArr));
        JestClientFactory factory = new JestClientFactory();
        factory.setHttpClientConfig(new HttpClientConfig.Builder(serverUris)
                .multiThreaded(multiThreaded)
                .defaultMaxTotalConnectionPerRoute(maxTotalConnectionPerRoute)
                .maxTotalConnection(maxTotalConnection)
                .maxConnectionIdleTime(connectionIdleTime, TimeUnit.MILLISECONDS)
                .connTimeout(connTimeout)
                .readTimeout(readTimeout)
                .gson(new GsonBuilder().setDateFormat(DateUtil.TimeFormat.NORMAL_PATTERN.getValue()).create())
                .build());
        return factory.getObject();
    }
}
use client:
    @Resource
    @Qualifier(value = "getJestClient")
    private JestClient jestClient;
    @Autowired
    private JestClientConfig jestClientConfig;
retry:
public <T extends JestResult> T execute(Action<T> clientRequest, int retryTimes) {
        if (retryTimes <= 0) {
            return null;
        }
        try {
            return ngccJestClient.execute(clientRequest);
        } catch (Exception e) {
            LOGGER.warn("ElasticsearchService.execute(): execution met an error, retryTimes = {}", retryTimes, e);
            return execute(clientRequest, --retryTimes);
        }
    }
