代码
<%@ page language= "java " contentType= "text/html; charset=GBK "%>
<%
//request.setCharacterEncoding( "GBK ");
String contentId = request.getParameter( "contentId ");
%>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=GBK ">
<title> Jsp Test </title>
</head>
<body>
<form method = "post " action= "ActionVerify.jsp ">
<table>
<tr>
<td>
<input name = "contentId " type = "text " value= " <%=contentId %> ">
</td>
<td>
<input name = "submit " type = "submit " value= "提交 ">
</td>
</tr>
</table>
</form>
</body>
</html>
<%@ page language= "java " contentType= "text/html; charset=GBK "%>
<%
//request.setCharacterEncoding( "GBK ");
%>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=GBK ">
<title> Insert title here </title>
</head>
<body>
<form action= " ">
<table>
<tr>
<td>
<%=request.getParameter( "contentId ") %>
</td>
</tr>
</table>
</form>
</body>
</html>
我已经设置了编码方式为GBK，但是我设置了request.setCharacterEncoding( "GBK ");就可以正常显示， <%@ page language= "java " contentType= "text/html; charset=GBK "%> 不能起到当前页面全局作用的效果吗？
