Answer 1

应该不是tomcat的启动内存问题。如果是内存问题 tomcat控制台会报javastack overflow 异常。你看下有没

Answer 3

既然在公司没事，就不是代码的问题
应该是环境，中间件tomcat之类的问题

Answer 4

“在登陆某个账户又退出之后电脑的cpu会连续在50%以上”这个指的服务器CPU还是客户端CPU

Answer 5

程序应该是没有问题，估计是环境方面的问题。  日志不要用debug打印出来，我之前碰到过类似的情况，在自己这边没有问题，到客户那边就出现问题，后来发现是日志打印太多出现过内存溢出。

Answer 6

这个软件的用户量基本上可以说是很少，而且也不是越来越慢，直接就是卡死，重启tomcat之后都有可能出现……

Answer 7

mysql默认连接数是100，但是使用软件的人数根本就没那么多啊。有的时候刚重启了tomcat之后就出现了卡死现象
