本文介绍了一种解决Struts2项目中出现的NullPointerException异常的方法。通过将struts.xml配置文件中的struts.devMode设置为false，可以避免该异常的发生。
exception starting filter struts2 java.lang.nullpointerexception
开发struts2项目遇到这个问题，我在struts.xml文件中：
<constant name="struts.devMode" value="true" />
把这个true改为false,问题就解决了，但是不知道是什么原因，有知道的留言谢谢

这是，由于tomcat的bug导致的，路径中不能有空格，将整个路径中的空格去掉。 当然，发布的时候，将struts2的开发模式设置为false，也可以在有空格路径的tomcat运行。...

原因：Struts2的拦截器异常，报了个空指针，google一下是Strut2的BUG，Tomcat路径不能包含空格。 解决：注释掉   或者修改Tomecat路径。

原因是设置 (调试模式) 后，struts有漏洞，tomcat安装路径出现空格的时候，会导致此异常抛出。例如我的安装路径为： C:\Tomcat 6.0\bin 注意 中间有空格 将其改为 C:\Tomcat6.0\bin 后 重启tomcat问题解决。
