第一百一十七天 how can I 坚持

web.xml配置：
<filter>
<filter-name>mobileFilter</filter-name>
<filter-class>com.oauth.system.utils.MobileFilter</filter-class>
<init-param>
<param-name>logonStrings</param-name><!-- 对登录页面不进行过滤 -->
<param-value>/mobileUser/forgetPassword;/mobileUser/init;/mobileUser/initLogin;/mobileUser/login;/mobileUser/initRegedit;/mobileUser/validateAccountCode;/mobileUser/validateBindPhone;/mobileUser/register;/mobileUser/sendVerifyCode;/mobileUser/verifyCode;</param-value>
</init-param>
<!--         <init-param>
<param-name>includeStrings</param-name>只对指定过滤参数后缀进行过滤
<param-value>.do;.jsp</param-value>
</init-param>   -->
<init-param>
<param-name>redirectPath</param-name><!-- 未通过跳转到登录界面 -->
<param-value>/mobileUser/initLogin</param-value>
</init-param>
</filter>
