�U�色字体为出错信息，原来以�ؓ是用Filter�Q�过滤器或者拦截器�Q�出错，因�ؓ�?font color=#333333>�?span lang=EN-US style="FONT-SIZE: 9pt; COLOR: #333333; FONT-FAMILY: Verdana; mso-font-kerning: 0pt; mso-bidi-font-family: 宋体">web.xml里的filter配置��L��Q�就正常��h��了，在网上查扑֏��C��U�情况：

1�?/font>�q�用Filte包不齐全
2�?/font>�W�二�U�情况：

google里搜�?/span>Error filterStart里有个文章说tomcat里的bug,没有实现javax.servlet.Filter�?/span>Filter会报�q�样的错误：

看来tomcat在启动就初始�?/span>Filter实例了，可能�?/span>Filter里的啥东东执行出错导致可能，看看Filter�?/span>init里用��C��?/span>

mServ = (ModuleService)WebUtils.getApplicationContext(config.getServletContext()).getBean("moduleService");

是最可能发生错误了，因�ؓ�q�里用到�?/span>spring�?/span>org.springframework.web.context.ContextLoaderServlet�Q�如果启动这时还没有建立�?/span>servlet实例�Q�务必导致获取失败，抛出错误。先屏蔽一下这句话�Q�果真启动正�怺��Q�修改一下代码，��?/span>init里的�q�句话丢��C��doFilter里面

if(mServ==null)
mServ = (ModuleService)WebUtils.getApplicationContext(filterConfig.getServletContext()).getBean("moduleService");

不过Tomcat也真是，解析web.xml的顺序上�q�是太僵��了�?/span>

我的出错情况�Q?/span>

�l�仔�l�推敲查扑֏�现是配置文�gstruts.xml配置时候action文�g名错�?/span>

原因�Q?/span>tomcat启动时会通过web.xml文�g��L��struts.xml文�g�?/span>又因struts2.0默认有拦截器的，所以如果这里的有错误信息，��׃��?/span>Filter错误�Q�很�Ҏ��引�v误导�?/span>
