我使用的是ElasticSearch和spring数据搜索，我在一个ec2示例中配置了ElasticSearch，所以最初我把网络主机设置为0.0.0.0，但是后来我把它绑定到网络主机上，网络主机是示例的私有ip，从中我得到了这个错误。尽管如果我卷一卷http://pvtip：9200工作正常http://pvtip：9200/nodes仅将传输层作为专用ip返回给我，但它仍然不起作用。我检查了在我的代码所在的ElasticBeanstalk示例中，是否配置了任何类型的elastic搜索，但它不存在
还要注意的是，这个错误只在我将代码移动到服务器时触发，甚至在jenkins构建作业的过程中也会触发
我做到了： sudo service elasticsearch status 它甚至不能识别ElasticSearch sudo netstat -ntlp 不返回为9200和9300打开的端口
完整堆栈跟踪如下：
