[main]
authc.loginUrl = /login
[users]
admin=123
user1=456
[urls]
/admin/** = authc
/index.jsp = authc
/=authc
/login.jsp = anon
[users]下注册的是用户名和密码用等号隔开。
/admin/** = authc 和 /index.jsp = authc 表示在admin目录下的资源和index.jsp被访问时都需要验证（用户名和密码）
/=authc 和 /login.jsp = anon 表示访问url为“/”的路径和/login.jsp不需要验证即可访问，/=authc 一定要加，因为“/”路径
默认访问index.jsp，这样 /login.jsp = anon 没有效果了。
login.jsp
