struts2中如何动态获取session对象
我正在尝试在 struts2 应用程序中动态获取会话对象。
<s:if test="%{#session['resToken'].bookingType == 1}">
resToken 可以通过
，但我不能写
它给了我双引号错误..
org.apache.jasper.JasperException: /WEB-INF/jsp/booking/banquet/guest-Info-View.jsp(150,40) Unterminated <s:if tag

你不能使用
${sessionScope.resToken.bookingType == 1}Can't you use
${sessionScope.resToken.bookingType == 1}如果我没看错的话，那么
resToken的值实际上是会话属性的名称，对吧？因此，请尝试类似：${sessionScope[resToken].bookingType}。If I'm reading that right, then the value of
resTokenis actually the name of a session attribute, right? So, try something like:${sessionScope[resToken].bookingType}.尝试将
%{resToken}适用于其中一个，那么它也应该适用于另一个。话虽如此，
%{#session['resToken'].bookingType}看起来是正确的。您是否尝试过输出它的值来看看它是什么？您还可以使用%{#session.resToken.bookingType}。首先确定您是否正确引用了会话变量，然后确保该值确实==1。或者您可以像其他人建议的那样使用 JSTL/JSP EL 并使用：
OGNL 参考
Trying to put an
<s:property/>tag inside of an<s:if/>tag isn't the right approach. Both tags take an OGNL expression as their argument. Therefore, if%{resToken}is working for one, it should work for the other too.With that said,
%{#session['resToken'].bookingType}looks correct. Have you tried outputting the value of that to see what it is? You can also use%{#session.resToken.bookingType}. First determine that you are properly referencing the session variable, then make sure that the value really does==1.Or you can use JSTL/JSP EL like the others suggested and go with:
OGNL Reference
'resToken' 不等于 resToken，后者是一个变量，您似乎希望第一个是字符串。
简单地写：
如果这不起作用，请使用属性标签输出表达式的较小部分以查看返回的内容。
'resToken' is not equal to resToken, the later is a variable which you seem to want the first is a string.
Simply write:
If this does not work please use property tags to output smaller parts of the expression to see what is returned.
我已经得到了它的解决方案..
首先是设置 resToken
检查 setTest
测试 11 测试 11
