In the JSP file you have : 在JSP文件中，您可以：
<c:forEach items="${cmpmst}" var="user" varStatus="loopCounter">
<tr>
<td><c:out value="${loopCounter.count}" /></td>
<td><c:out value="${cmpmst.cmpcode}" /></td>
while ${cmpmst} is an array . 而${cmpmst}是一个数组 。 You should write instead : 您应该改写：
<c:forEach items="${cmpmst}" var="user" varStatus="loopCounter">
<tr>
<td><c:out value="${loopCounter.count}" /></td>
<td><c:out value="${user.cmpcode}" /></td>
and same for following fields 和以下字段相同
I could not see how and where you forward to cmpmstaddedit.jsp in shown controller, but I assume that cmpmsts is also a list. 我看不到如何在显示的控制器中转发到cmpmstaddedit.jsp方式和位置，但我认为cmpmsts也是一个列表。 You must ensure that you put a single object as request attribute before forwarding to that view. 您必须确保在转发到该视图之前将单个对象作为请求属性。
