偶然碰到的东东...妙用的jstl...

个人愚见：可以得到当前某个容器参数的大小...首先需要导入jstl库..

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>

然后必要的时候会用到OpenEntityManagerInView，所以需要在WEB.XML文件中配置出..

<filter> <filter-name>Spring OpenEntityManagerInViewFilter</filter-name> <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>Spring OpenEntityManagerInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

搞定~比我以前的方法easy多了，美包包
