修改catalina.bat文件

\-verbose:gc  //开启GC日志

注意：-XX:+PrintGC 与 -verbose:gc 是一样的，可以认为-verbose:gc 是 -XX:+PrintGC的别名.  
  
\-XX:+PrintGCDateStamps //GC发生的时间信息

\-XX:+PrintGCDetails  //可以详细了解GC中的变化

\-XX:+PrintGCApplicationStoppedTime

//打印垃圾回收期间程序暂停的时间。  
输出形式：Total time for which application threads were stopped: 0.0002369 seconds, Stopping threads took: 0.0000395 seconds  
\-XX:+PrintGCApplicationConcurrentTime

//打印每次垃圾回收前，程序未中断的执行时间。

输出形式 ：  Application time: 0.2952408 seconds
