在这里插入图片描述

解决方案：

参考博客：https://blog.youkuaiyun.com/gudada010/article/details/100836868

动态引入或转发标签中间加入了空格或注释

在动态引入或转发标签的两个标签中间除了写<jsp:param name="" value="" />子标签不会报错，其他任意字符都会报错。

报错的情况 ：
<jsp:forward page="/jsptag2.jsp">
    <%--转发的时候，携带的参数--%>
    <jsp:param name="username" value="root"></jsp:param>
    <jsp:param name="password" value="admin"></jsp:param>
</jsp:forward>



不报错的情况 ：
<%--转发的时候，携带的参数--%>
<jsp:forward page="/jsptag2.jsp">
    <jsp:param name="username" value="root"></jsp:param>
    <jsp:param name="password" value="admin"></jsp:param>
</jsp:forward>
