Property 'date' not found on type java.lang.String] with root cause解決方案
今晚的開發極其不順利,一個小小的bebug都找了一個多小時.
如果你也報這個錯,先看下el表達示是不是一個物件,如果是字串，這樣才會後面用EL取值的時候not found on type java.lang.String了
如果是一個物件那麼請再看下面的

這個才是重點"PropertyNotFoundException: Property 'date' not found on type "
之前一直的el表達示,今晚就是一直報這個錯,真心不是後臺的錯,而是前臺粗心造成的,我之前程式碼為 <c:forEach items="${requestScope.listSubset } " var="su"><li><c:out value="${su.title }"</li>
</c:forEach>
之後程式碼是這樣的 <c:forEach items="${requestScope.listSubset }"
<li><c:out value="${su.title }"</li>
</c:forEach>
看到了有什麼區別嗎,就不一個空格.之前的多了一個空格呀!!!!!!!找了我一個多小時.............
