我已经在安装了tomcat7的VPS(OVH)上部署了Jhipster应用程序。
几天来,申请似乎很慢。
一旦我启动tomcat,我就做一个netstat-tanpu,得到以下连接:

我想知道我的问题是否与127.0.0.1:3306和xx.xx.xxx.xxx:8080(java和mysqld)的许多连接有关

最佳答案

有一个连接池,因此可以打开多个连接,而不会导致任何特定问题。
您可以在“监视”屏幕中检查连接池的状态,当然,您也可以运行JConsole来获得更详细的信息(我们使用的是HikariCP,它通过JMX导出很多数据)

关于mysql - Jhipster消耗大量资源,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/28426489/
