Cannot convert 0:0 of type class java.lang.String to class java.lang.Long

 

<----jsp页面内容---->

<span class="sp">订单状态：
          <c:if test="${prop.status == 0}"><font color="#000080">下单登记</font></c:if>
          <c:if test="${prop.status == 1}"><font color="green">支付成功</font><img src="images/g.gif"></c:if>
          <c:if test="${prop.status == 3}"><font color="red">待支付</font><img src="images/X.gif"></c:if>
          <c:if test="${prop.status == 2}"><font color="blue">支付确认</font><img src="images/f.gif"></c:if>
          <c:if test="${prop.status == -1}"><font color="red">支付失败</font><img src="images/X.gif"></c:if>
 </span>

造成错误：

造成原因：status为string型，而页面判断的是整形，所以报错

修改方法：<span class="sp">订单状态：
          <c:if test="${prop.status == ‘0’}"><font color="#000080">下单登记</font></c:if>
          <c:if test="${prop.status == ‘1’}"><font color="green">支付成功</font><img src="images/g.gif"></c:if>
          <c:if test="${prop.status == ‘3’}"><font color="red">待支付</font><img src="images/X.gif"></c:if>
          <c:if test="${prop.status == ‘2’}"><font color="blue">支付确认</font><img src="images/f.gif"></c:if>
          <c:if test="${prop.status == ‘-1’}"><font color="red">支付失败</font><img src="images/X.gif"></c:if>
