Spring Security,表单登录和并发会话

Question

我试图限制用户多次签名(强制前一个会话到期).

我检查了这个专题的文件在这里.我将其设置为非常类似于文档,但用户一次不限于一个会话.我可以使用同一个用户多次登录(在不同的浏览器中)并且有多个并发会话.

以下是我认为是我的安全设置的相关内容.我正在使用自定义UserDetailsS​​ervice,UserDetails和AuthenticationFilter实现.

    <http entry-point-ref="authenticationEntryPoint">
        <!-- Make sure everyone can access the login page -->
        <intercept-url pattern="/login.do*" filters="none" />

        [...]

        <custom-filter position="CONCURRENT_SESSION_FILTER" ref="concurrencyFilter" />
        <custom-filter position="FORM_LOGIN_FILTER" ref="authenticationFilter" />

        <logout logout-url="/logout" logout-success-url="/login.do" />
    </http>

    <authentication-manager alias="authenticationManager">
        <authentication-provider user-service-ref="userDetailsService">
            <password-encoder hash="sha" />
        </authentication-provider>
    </authentication-manager>

    <beans:bean id="userDetailsService" class="[...]">
        <beans:property name="userManager" ref="userManager" />
    </beans:bean>

    <beans:bean id="authenticationFilter" class="[...]">
        <beans:property name="authenticationManager" ref="authenticationManager" />
        <beans:property name="eventPublisher">
            <beans:bean
                class="org.springframework.security.authentication.DefaultAuthenticationEventPublisher" />
        </beans:property>
        <beans:property name="filterProcessesUrl" value="/security_check" />
        <beans:property name="authenticationFailureHandler">
            <beans:bean
                class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
                <beans:property name="defaultFailureUrl" value="/login.do?login_error=true" />
            </beans:bean>
        </beans:property>
        <beans:property name="sessionAuthenticationStrategy"
            ref="sessionAuthenticationStrategy" />
    </beans:bean>

    <beans:bean id="authenticationEntryPoint"
        class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
        <beans:property name="loginFormUrl" value="/login.do" />
    </beans:bean>

    <beans:bean id="concurrencyFilter"
        class="org.springframework.security.web.session.ConcurrentSessionFilter">
        <beans:property name="sessionRegistry" ref="sessionRegistry" />
        <beans:property name="expiredUrl" value="/login.do?login_error=true!" />
    </beans:bean>

    <beans:bean id="sessionAuthenticationStrategy"
        class="org.springframework.security.web.authentication.session.ConcurrentSessionControlStrategy">
        <beans:constructor-arg name="sessionRegistry"
            ref="sessionRegistry" />
        <beans:property name="maximumSessions" value="1" />
    </beans:bean>

    <beans:bean id="sessionRegistry"
        class="org.springframework.security.core.session.SessionRegistryImpl" />

我还在org.springframework.security.web.session.HttpSessionEventPublisher我的web.xml文件中注册为监听器.

据我所知,我已根据文档配置了这个.我不知道为什么这不起作用.它是否与我使用基于表单的登录这一事实有关？或者我上面提到的自定义实现？

Answer 1

我想到了.如果重新实现UserDetails,则必须为SessionRegistryImpl提供hashCode()方法才能使用.文档中未提及此内容.
