**项目是dubbo+zookeeper+SSM+redis+Maven的，seivice和web分层，service启动没问题，web放进tomcat启动报错

#在线等# 求大佬
应该是类没找到，你可以写个servlet，在servlet中手动用Class.forName("com.cityparlor.web.listener.WebContextListener");看看能不能加载。
如果不能加载你手动将WebContextListener.class拷贝到WEB-INF\class下，按包名创建相应的目录最终将WebContextListener.class文件放进去，重启tomcat再试试。
再者检查WebContextListener所依赖的类是否存在jar包没导入的情况
Error configuring application listener of class com.cityparlor.web.listener.WebContextListener
看报错这句，说是application的配置文件里会加载WebContextListener，但是找不到这个依赖包。
右键项目-》Properties-》add-》选Java Builld Path Enteires-》Next-》Maven Dependencies-》Finish-》OK
然后Clean项目，重启试试
