背景：写一个新功能时用了javafx.util包下的Pair类，本地调试没问题，但是部署到测试环境时使用jenkis一直在重试健康检查，
FAILED - RETRYING: Healthcheck | Wait for ysdq-long-bms to be healthy on URLs [u’http://localhost:8008/actuator/health’] (28 retries left).
正常情况下重试几次就会成功，这次一直失败。

1、解决问题的思路 先看了linux下的 /var/log/message目录
因为这个是系统日志，可以看到错误，结果没发现，说明服务是启动了，在运行中一直在健康检查失败
2、检查access.log
这个是服务打印的日志，最后才想起来这个日志，直接使用cat命令打印文件一下子就看到了报错。

解决办法也很简单，要么添加依赖或者用别的包下的Pair
最后改成了apache下的可以了
这个是依赖。
