spring security默认的登录界面太丑，自己定义了一个，配置如下：
<http auto-config="true">
<intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
<form-login login-page="login.jsp" authentication-failure-url="login.jsp?error=true" default-target-url="index.jsp" />
</http>报错了如下：

解决方法：
仅仅是因为配置的地址都需要加各斜杠/
<http auto-config="true">
<intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
<form-login login-page="/login.jsp" authentication-failure-url="/login.jsp?error=true" default-target-url="/index.jsp" />
</http>
