我新加了一个 LoginFilter，两种方法加入：
1，在 web.xml 中写入

    <filter>
        <filter-name>login</filter-name>
        <filter-class>cn.leancloud.gitrac.LoginFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>login</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

2，在源文件中通过 annotation 标注：

@WebFilter(filterName = "loginFilter", urlPatterns = {"/*"})
public class LoginFilter implements Filter {
}

发现 LoginFilter 的初始化都在 RequestUserAuthFilter 初始化之前，并且 filterChain 的处理上，LoginFilter 也在 RequestUserAuthFilter 之前。
这样导致不能根据 currentUser 的有无来判断用户是否登录。
