Elasticsearch在linux服务器部署后，java项目启动报错，windows服务器正常运行，如何避坑？
1、问题描述
之前在windows服务器上部署了java项目（springboot）,ES安装版本7.13.1，正常运行。后因特殊要求迁移到linux服务器上，按照windows服务器版本依然安装7.13.1的ES，启动java项目报错，错误信息如下：

2、分析问题
经过大量资料的检索，及代码版本比对，发现Java项目引用elasticsearch的maven版本为7.12.1，而ES安装版本为7.13.1，这种情况在windows服务器可以正常运行，但是windows下Java项目调用6.4.2的ES时复现了我的linux服务器的问题，基本确定问题出现在
java项目引用的es版本与本地部署的ES存在版本差异所导致。
3、解决问题
果断卸载linux系统中的7.13.1版本的ES，重装7.12.1版本，问题解决！！！
4、总结经验
确保Java项目引用ES的版本与部署的ES版本保持版本一致性。（当然偶尔小版本的差异可能依然正常，为了避坑，请不要存在侥幸，要知道研发中很多问题都是不严谨的态度造成的）
