如何在struts标记中获取JSP scriptlet值

Here is my code:

这是我的代码:

<% request.setAttribute("lcItem", "Hello"); %>

If I do as following, I'm not getting the value:

如果我这样做,我没有得到价值:

<s:property value="%{lcItem}" />
<s:property value="lcItem" />

Any suggestions?

This works perfectly..

这完美地工作..

<%       
   request.setAttribute("lcItem", LeftContentItem);
%>

<s:property value="#request['lcItem']" />

Note: According to the Scope we use we should specify the #request .. etc

注意:根据我们使用的范围,我们应该指定#request ..等

You can write your code 2 ways

您可以通过2种方式编写代码

<% request.setAttribute("lcItem", "Hello"); %>

<%request.setAttribute(“lcItem”,“Hello”); %>

<% pageContext.setAttribute("lcItem", "Hello"); %>

<%pageContext.setAttribute(“lcItem”,“Hello”); %>

then if you want to access these values in Struts2 Components you might use #attr. as prefix.

那么如果你想在Struts2组件中访问这些值,你可以使用#attr。作为前缀。

Example

<s:property value="#attr.lcItem">

Note: It will work fine with request and "pageContext".

注意:它可以正常处理请求和“pageContext”。

<s:property value="lcItem" /> will not work because "lcItem" is not available in the Value Stack.
