问题描述
非常快速的问题.有人可以向我解释为什么此代码不起作用吗?
Very quick questions.Could someone explain to me why this code does not work?
<%@ taglib prefix="logic" uri="/WEB-INF/struts-logic.tld" %>
<%
int myValue= 2;
%>
myValue: <%=myValue%>
<br/>
<logic:equal name="myValue" value="2" scope="session">
logic:equal works!
</logic:equal>
即使我将myValue更改为String仍然不起作用
Even if I change myValue to a String is still doesn't work
非常令人沮丧,因为我知道这将是显而易见的.
Quite frustrating, cause I know it's going to be something obvious.

工作示例!
<%@ taglib prefix="logic" uri="/WEB-INF/struts-logic.tld" %>
<%
request.setAttribute("myValue", 2);
%>
myValue - <%=request.getAttribute("myValue")%>]]
<br/>
<logic:equal name="myValue" value="2" scope="request">
logic:equal works!
</logic:equal>
推荐答案
<logic:equal name="myValue" value="2" scope="session">
此标记查找名为"myValue"的会话属性.不适用于名为"myValue"的局部变量.
This tag looks for a session attribute named "myValue". Not for a local variable named "myValue".
真正的问题是:为什么要使用标记为不赞成使用JSTL的标记库,而该库是正式废弃的框架的一部分?
The real question is: why are you using a tag library which is marked as deprecated in favor of the JSTL, this library being part of a framework which is officially abandoned?
