一.在web.xml中配置listener<listener><listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class></listener>二.在security.xml中配置HibernateORM提供了三种继承映射策略<session-management><concurrency-control max-sessions="1" error-if-maximum-exceeded="true"/></session-management> max-sessions表示最多允许多少次重复登录。如果没有配置error-if-maximum-exceeded，那么用户账号的第二次登录会使第一次登录失效，而配置了的话，那么第二次登录会被阻止。通常的做法是阻止第二次登录。 <无> .CodeEntity .code_pieces ul.piece_anchor{width:25px;position:absolute;top:25px;left:-30px;z-index:1000;}.CodeEntity .code_pieces ul.piece_anchor li{width:25px;background: #efe;margin-bottom:2px;}.CodeEntity .code_pieces ul.piece_anchor li{border-left:3px #40AA63 solid;border-right:3px #efe solid;}.CodeEntity .code_pieces ul.piece_anchor li:hover{border-right:3px #40AA63 solid;border-left:3px #efe solid;}.CodeEntity .code_pieces ul.piece_anchor li a{color: #333;padding: 3px 10px;}.CodeEntity .code_pieces .jump_to_code{visibility:hidden;position:relative;}.CodeEntity .code_pieces .code_piece:hover .jump_to_code{visibility:visible;}.CodeEntity .code_pieces .code_piece:hover .jump_to_code a{text-decoration:none;}.CodeEntity .code_pieces h2 i{float:right;font-style:normal;font-weight:normal;}.CodeEntity .code_pieces h2 i a{font-size:9pt;background: #FFFFFF;color:#00A;padding: 2px 5px;text-decoration:none;}
