为什么会出现乱码？
Test.jsp:<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<html>
<body>
<form action="Test2.jsp" method="post">
<input name="user" type="text">
<input type="submit" value="提交">
</form>
</body>
</html>
Text2.jsp:
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<%request.setCharacterEncoding("GB2312"); %>
<html>
<body>
<h1><%=request.getParameter("user") %></h1>
</body>
</html>
