同学你好。这边两位老师尝试,都没能复现你的问题。但看到同学的page使用有些错误,可以先改正一下试试:

<%@ page contentType="text/html; UTF-8" pageEncoding="UTF-8" %>

改为:

<%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8" %>

一般而言,出现这样显示是因为文件类型并不是jsp类型。而是html或者其他类型。同学也可以检查一下。

如果解答了同学的疑问,望采纳~

祝学习愉快~

    同学是不是所有的jsp页面都是如此呢?可以在你的项目中新建一个简单的jsp页面试一下,关键是和乱掉的页面相同的html结构和头部声明。

    我把 jsp页面放到 /resources/templates/下了, 其他jsp页面也还是相同的问题

问题已解决,确定采纳
还有疑问,暂不采纳

恭喜解决一个难题,获得1积分~
