最后一定要在web.xml中配置加上：

<!-- Spring Security Session -->
<listener>
<listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>

<!-- Spring security Filter -->

</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
启动Tomcat，登录正常工作。
