Spring security 设置多登陆页面，security 3.1
xml配置信息如下：

<http auto-config='true' use-expressions="true">
        <logout />
        <session-management></session-management>
        <form-login login-page="/index" authentication-failure-url="/index?login_error=t"   always-use-default-target="true" default-target-url="/"></form-login>
        <custom-filter ref="myFilter" before="FILTER_SECURITY_INTERCEPTOR" />
    </http>

尝试过配置多个，但没有成功，只一个登陆页面出来
xml 配置信息如下:

<http auto-config='true' pattern="/admin" use-expressions="true"> 
        <logout />
        <session-management></session-management>
        <remember-me />
        <form-login login-page="/index" authentication-failure-url="/index?login_error=t"
            always-use-default-target="true" default-target-url="/"></form-login>
            <custom-filter ref="myFilter" before="FILTER_SECURITY_INTERCEPTOR" />
</http>
<http auto-config='true' pattern="/user" use-expressions="true">
        <logout />
        <session-management></session-management>
        <remember-me />
        <form-login login-page="/login" authentication-failure-url="/login?login_error=t"
            always-use-default-target="true" default-target-url="/"></form-login>
        <custom-filter ref="myFilter" before="FILTER_SECURITY_INTERCEPTOR" />
</http>

页面报错如下：
HTTP Status 405 - Request method 'GET' not supported

单登陆页面配置如下：
