在 LocalAuthorizingRealm 中，用戶登錄進行認證之前，先將該用戶的其他session移除：

@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
String userName = (String)authenticationToken.getPrincipal();
//處理session
DefaultWebSecurityManager securityManager = (DefaultWebSecurityManager) SecurityUtils.getSecurityManager();
DefaultWebSessionManager sessionManager = (DefaultWebSessionManager)securityManager.getSessionManager();
Collection<Session> sessions = sessionManager.getSessionDAO().getActiveSessions();//獲取當前已登錄的用戶session列表
for(Session session:sessions){
//清除該用戶以前登錄時保存的session
if(userName.equals(String.valueOf(session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY)))) {
sessionManager.getSessionDAO().delete(session);
}
}
String pwd = null;
return new SimpleAuthenticationInfo(userName,pwd,getName());
}
