Property 'date' not found on type java.lang.String] with root cause解决方案

今晚的开发极其不顺利,一个小小的bebug都找了一个多小时.

如果你也报这个错,先看下el表达示是不是一个对象,如果是字符串，这样才会后面用EL取值的时候not
found on type java.lang.String了

如果是一个对象那么请再看下面的

这个才是重点"PropertyNotFoundException: Property 'date' not found on type "

之前一直的el表达示,今晚就是一直报这个错,真心不是后台的错,而是前台粗心造成的,我之前代码为
<c:forEach items="${requestScope.listSubset
} "  var="su">
<li><c:out value="${su.title }"</li>
</c:forEach>

之后代码是这样的
<c:forEach items="${requestScope.listSubset
}"  var="su">
<li><c:out value="${su.title }"</li>
</c:forEach>

看到了有什么区别吗,就不一个空格.之前的多了一个空格呀!!!!!!!找了我一个多小时.............
