首页


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>首页</title>
</head>
<body>
这是首页
</body>
</html>

index.jsp 这个页面 加上
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
你这个代码 只是一个页面,所以 跟后台没太大关系, 加了这个应该就可以了

有帮助的话 请采纳


你的jsp页面有没有<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
 html有没有<meta charset="utf-8">
