You can't iterate over prdtobject i.e., you are using forEachtag and prdtis not a Listobject, so to solve the issue simply remove <c:forEach var="x" items="${prdt}">or else you need to return a listobject from your Contoller.
您不能迭代prdt对象，即，您使用的是forEach标记而prdt不是List对象，因此要解决该问题，只需删除即可<c:forEach var="x" items="${prdt}">，否则您需要list从控制器返回一个对象。
Your JSP looks as below (after removing <c:forEach):
您的 JSP 如下所示（删除后<c:forEach）：
<table>
<img src="resources/Images/${x.id}.png"/>
<td>
<c:out value="${prdt.product_Name}"/></td>
<td>
<c:out value="${prdt.descripction}"/></td>
<td>
<c:out value="${prdt.price}"/></td>
<td>
<c:out value="${prdt.mfg_Date}"/>
</td>
</table>
