报错信息如下：
org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{MXkg7HdyTo6tkKSHVTcAUg}{10.0.0.43}{10.0.0.43:9200}]
at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:352)
at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:248)
at org.elasticsearch.client.transport.TransportProxyClient.execute(TransportProxyClient.java:60)
解决办法：看报错信息是服务器ES节点有问题，若是集群模式，建议更换别的ES节点即可测试成功。
