el表达式跟ognl表达式的区别

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1.区别 用法区别： OGNL是通常要结合Struts 2的标志一起使用，如<s:property value="#xx" /> struts页面中不能单独使用，el可以单独使用 ${sessionScope.username} 页面取值区别： 用于按request > session > application顺序访问其属性（attribute） #attr.userName相当于按顺序在以上三个范围（scope）内读取userName属性，直到找到为 2.ognl讲解 OGNL 是 Struts 2默认的表达式语言。是Object Graphic Navigation Language（对象图导航语言）的缩写，它是一个开源项目。 1．#符号的用途一般有三种。 1)访问非根对象属性，例如示例中的#session.msg表达式，由于Struts 2中值栈被视为根对象，所以访问其他非根对象时，需要加#前缀。实际上 ，#相当于ActionContext.getContext()； ；#session.msg表达式相当于ActionContext.getContext().getSession(). getAttribute(”msg”) 。 2)用于过滤和投影（projecting）集合，如示例中的persons.
