jsp代码

<c:forEach items="${usersList}" var="${user}">
    <tr>
        <td>123123123</td>
        <td>${user.username}</td>
        <td>${user.password}</td>
        <td>${user.phoneNum}</td>
        <td>${user.email}</td>
        <td>${user.status}</td>
        <td>${user.registerTime}</td>
        <td>
            <button type="button" value="修改">修改</button>
            <button type="button" value="删除">删除</button>
        </td>
    </tr>
</c:forEach>

错误原因：

    <c:forEach items="${usersList}" var="${user}">

应该是：var="user",不应该加上${}
