如果jsp:include 中的page页面存在乱码，则需要在使用<jsp:include page=""> 的页面中的<body>后加上
<%
request.setCharacterEncoding('UTF-8") ;//或者指定的编码(GBK或其他)
%>
如下面所示：
复制代码 代码如下:
jsp-include.jsp
<%@ page language="java" contentType="text/html;charset=UTF-8" %>
<html>
<head><title>jsp include测试页</title></head>
<body>
<%
request.setCharacterEncoding("UTF-8") ;
%>
<h3>jsp include 指令测试</h3>
<jsp:include page="forward-result.jsp">
<jsp:param name="age" value="32" />
<jsp:param name="username" value="张三" />
</jsp:include>
</body>
</html>
forward-result.jsp
<%@ page language="java" contentType="text/html;charset=UTF-8" %>
<html>
<head><title>forward的结果页</title></head>
<body>
年龄：<%=request.getParameter("age")%><br />
姓名：<%=request.getParameter("username") +"--11"%>
</body>
</html>
