弹簧安全中的多个登录表单

Question

我是春天的新手,在我的项目中,我需要通过spring security为管理员和用户添加两个登录表单.到目前为止,我能够成功创建一个登录页面.这是我的 spring-security.xml

<beans:beans xmlns="http://www.springframework.org/schema/security"
             xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/security
    http://www.springframework.org/schema/security/spring-security-3.2.xsd">

    <!-- enable use-expressions -->
    <http auto-config="true" use-expressions="true">
        <intercept-url pattern="/admin**" access="hasRole('ROLE_ADMIN')" />
        <intercept-url pattern="/welcome*" access="isAnonymous()"/>
        <intercept-url pattern="/signup*" access="isAnonymous()"/>
        <!--<intercept-url pattern="/login*" access="isAnonymous()" />-->
        <intercept-url pattern="/selection" access="isAuthenticated()"/>
        <intercept-url pattern="/dashboard" access="isAuthenticated()"/>

        <!-- access denied page -->
        <access-denied-handler error-page="/403" />
        <form-login
                login-page="/login"
                default-target-url="/selection"
                authentication-failure-url="/login?error"
                username-parameter="username"
                password-parameter="password" />
        <logout logout-success-url="/login?logout"  />
        <!-- enable csrf protection -->
        <csrf/>
    </http>

    <!-- Select users and user_roles from database -->
    <authentication-manager>
        <authentication-provider user-service-ref="myUserDetailsService" >
            <password-encoder hash="plaintext" />
        </authentication-provider>
    </authentication-manager>


    <beans:bean id="myUserDetailsService" class="com.cse.cloud4s.service.MyUserDetailsService"/>
</beans:beans>

web.xml中

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring-security.xml,
        /WEB-INF/spring-database.xml
    </param-value>
</context-param>


<!-- Spring Security -->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

如何修改代码以使用多个登录页面？

Answer 1

您可以拥有任意数量的登录页面,但只有一个默认登录页面,如果用户未经过身份验证,则弹出安全性会重定向到该页面 - 无论如何,如果用户想要以管理员身份登录,那么在身份验证之前很难猜到.

唯一的规则是所有登录页面必须将相同的字段提交给相同的URL,并且该URL由spring security处理.

我唯一的问题是为什么你需要多个登录页面？Spring安全方式是将权限附加到登录名,而不是您登录的方式.
