部分 .do 过滤不了
 
经测试,发现是命名问题
例如: 第一个 Action 的名字为 UserAction
        第二个 Action 的名字为 UserInfoAction
        第三个 Action 的名字为 AddUserAction
 
这样命名就导致第二第三个action 过滤失效]]>https://blog.youkuaiyun.com/epfeng/article/details/5921088https://blog.youkuaiyun.com/epfeng/article/details/5921088epfengMon, 04 Oct 2010 13:54:00 +0800MessageResources resources = MessageResources.getMessageResources("com.config.ApplicationResources");
