Grails Spring Security 最大并发会话

Question

我有带有 spring 安全插件 (2.0-RC5) 的 grails 2.5.1 应用程序。我想阻止每个用户的当前会话数。我读了一些博客，但它不起作用。(http://www.block-consult.com/blog/2012/01/20/restricting-concurrent-user-sessions-in-grails-2-using-spring-security-core-plugin/) 我的资源.groovy

beans = {
  sessionRegistry(SessionRegistryImpl)

    concurrencyFilter(ConcurrentSessionFilter,sessionRegistry,'/main/index'){
        logoutHandlers = [ref("rememberMeServices"), ref("securityContextLogoutHandler")]
    }
    concurrentSessionControlStrategy(ConcurrentSessionControlAuthenticationStrategy, sessionRegistry) {
        exceptionIfMaximumExceeded = true
        maximumSessions = 1

    }
}

在我的 boostrap.groovy 中

 def init = { servletContext ->
    SpringSecurityUtils.clientRegisterFilter('concurrencyFilter', SecurityFilterPosition.CONCURRENT_SESSION_FILTER)
  }

我的 config.groovy 我已经添加了这个：

grails.plugin.springsecurity.useHttpSessionEventPublisher = true

谢谢..

首先，如果您决定继续使用我的解决方案，请让我警告您。

• SessionRegistryImpl 不可扩展。您需要根据您的扩​​展计划（例如数据网格）创建自己的可扩展实现。会话复制还不够。
• 目前，默认注销处理程序没有正确删除 SessionRegistry。所以我创建了一个名为 CustomSessionLogoutHandler 的示例注销处理程序。
• 您必须覆盖 grails spring-security-core 登录控制器来处理 SessionAuthenticationException。
• 您可以将可以登录 maximumSessions = 1 的用户数更改为 -1 以获得无限会话。

首先，在 resources.groovy 中

import org.springframework.security.core.session.SessionRegistryImpl;
import org.springframework.security.web.authentication.session.ConcurrentSessionControlAuthenticationStrategy;
import org.springframework.security.web.authentication.session.SessionFixationProtectionStrategy;
import org.springframework.security.web.authentication.session.RegisterSessionAuthenticationStrategy;
import org.springframework.security.web.authentication.session.CompositeSessionAuthenticationStrategy;
import com.basic.CustomSessionLogoutHandler


// Place your Spring DSL code here
beans = {

sessionRegistry(SessionRegistryImpl)

customSessionLogoutHandler(CustomSessionLogoutHandler,ref('sessionRegistry')    )

concurrentSessionControlAuthenticationStrategy(ConcurrentSessionControlAuthenticationStrategy,ref('sessionRegistry')){
    exceptionIfMaximumExceeded = true
    maximumSessions = 1
}

sessionFixationProtectionStrategy(SessionFixationProtectionStrategy){
    migrateSessionAttributes = true
    alwaysCreateSession = true
}
registerSessionAuthenticationStrategy(RegisterSessionAuthenticationStrategy,ref('sessionRegistry'))

sessionAuthenticationStrategy(CompositeSessionAuthenticationStrategy,[ref('concurrentSessionControlAuthenticationStrategy'),ref('sessionFixationProtectionStrategy'),ref('registerSessionAuthenticationStrategy')])

}

在 config.groovy 中确保 customSessionLogoutHandler 位于 securityContextLogoutHandler 之前：

grails.plugin.springsecurity.logout.handlerNames = ['customSessionLogoutHandler','securityContextLogoutHandler'] 

ConcurrentSessionControlAuthenticationStrategy 使用这个 i18n。因此，您可以使用您的语言：

ConcurrentSessionControlAuthenticationStrategy.exceededAllowed = Maximum sessions for this principal exceeded. {0}

这是我的示例CustomSessionLogoutHandler，您可以将其保存在 src/groovy/com/basic/CustomSessionLogoutHandler.groovy 中：

public final class CustomSessionLogoutHandler implements LogoutHandler {
    private final SessionRegistry sessionRegistry;

    /**

     * @param sessionRegistry the {@link SessionRegistry} to use
     */
    public CustomSessionLogoutHandler(SessionRegistry sessionRegistry) {
        Assert.notNull(sessionRegistry, "sessionRegistry cannot be null");
        this.sessionRegistry = sessionRegistry;
    }

    /**
     * Clears the {@link SessionRegistry}
     *

    public void logout(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) {
        this.sessionRegistry.removeSessionInformation(request.getSession().getId());
    }
}

如果您也需要，我的示例登录控制器（我从源代码复制）。只需在项目中另存为普通控制器，因为它将覆盖默认值。当我处理 SessionAuthenticationException 时，请参见下面的第 115 行：
