出错服务一直没有动过，最近添加了几个服务到tomcat下，没想到影响到之前的。 访问直接拋异常，500错误

原因：
EL表达式的错误
解决办法：
编辑tomcat/conf/context.xml文件，在<Context>标记下添加<Loader delegate="true" />

1 2 3 4 5 |
<Context> <Loader delegate="true" /> <!-- Default set of monitored resources --> <WatchedResource>WEB-INF/web.xml</WatchedResource> </Context> |
