linux 环境 tomcat 莫名奇妙挂掉

J2EE项目 本地运行无误，服务器运行，一段时间后报nullpointerException，但却不影响正常使用。

网上查到的原因：

1 环境jdk和tomcat版本原因；更换版本，然并卵。

2 域名配置原因；http://www.ithao123.cn/content-928555.html

需要在server.xml中的<Engine name="Catalina" defaultHost="localhost">标签下配置一个<Host name="localhost" >，这样他的defaultHost的值才不会被忽略，defaulthostname才会有值，这样就解决了那个tomcat运行时不时的报一个NullPointerException。

推荐：http://blog.csdn.net/u012906938/article/details/36718809

有结点配置，看了就明白为毛要报null指针。

但是看看还是有好处的，解决了我的另一个问题

本地服务器正常，但服务器spring mvc 定时任务跑两次

还是域名配置问题

另外还有个spring mvc多个定时任务执行的小问题： 假如之前执行的一个定时任务没结束，下面的不执行的。

最后，域名配置指定项目方法。

tomcat 域名绑定到指定的项目上，也就是说http://localhost:8080/项目名=http://域名

1 更改8080 端口为80端口

2 修改上图划红蓝线的地方（蓝线那行是添加的），要说明的是 appBase="webapps"也是会运行你的定时器的，下面子结点再运行一次，可不就运行两次么

3 服务器host文件最好改，虽然不改也没什么。
