报错日志没有发现一个业务代码报错信息，全是 Java 和 tomcat 自身的错误信息。由此推断出是 tomcat 的虚拟机内存参数给的太小了。
可以打开 JDK bin 目录下的 jvisualvm.exe 来观察 Java 虚拟机的内存使用情况。
观察堆内存使用情况
观察 PermGen 使用情况
解决方案：
在 tomcat 的 catalina.bat 文件中修改（或加入）虚拟机参数，加在 set "CURRENT_DIR=%cd%" 下面
set JAVA_OPTS=-Xms256m -Xmx512m -XX:PermSize=128M -XX:MaxNewSize=256m -XX:MaxPermSize=256m -Djava.awt.headless=true
修改后重启 tomcat，再次复现之前的功能，日志中就会报出业务代码里面的问题，然后我们就可以开始去解决真正的代码问题。

通过日志发现是 CpUserControl.java:293 处可能是因为数据没有查到导致的空指针问题，那么接下来解决没有数据的问题就好了。
