struts2标签判断字符串

11:<s:property value='#attr.jxwReadyOnly'/>
22:<s:property value='#attr.jxwReadyOnly=="jxwReadyOnly"'/>
33:<s:property value='#session.get("jxwReadyOnly")=="jxwReadyOnly"'/>
44:<s:property value="#session.jxwReadyOnly=='jxwReadyOnly2'"/>
55：<s:property value='%{#session.jxwReadyOnly=="2jxwReadyOnly"}'/>

输出：11:jxwReadyOnly 22:true 33:true 44:false 55：fasle

总结：

1、单引号里用双引号，双引号里就用单引号

2、#session.get("jxwReadyOnly") 和#session.jxwReadyOnly 都可以取值

3、可用attr

4、引号里可以直接跟#号，而不用%{}，当然加上%{}不会出错

<s:if test='%{#session.jxwReadyOnly=="jxwReadyOnly"}'>
和<s:if test='#session.jxwReadyOnly=="jxwReadyOnly"'> 都可以
