servlet传中文显示乱码，请教。
本帖最后由 dx8439 于 2013-08-17 09:56:55 编辑 servlet传中文给jsp页面显示不出来，jsp页面像servlet提交一个叫name的文本值，servlet接收到后进行数据库操作，再把这个值返回给jsp页面，但是我从servlet打印出来的是中文，返回页面后中文显示不出来，用了getBytes("iso-8859-1"),"gb2312"方法也不行，请教大家。下面是页面和servlet。
jsp:
<%@ page language="java" import="java.util.*,com.bean.Bean" pageEncoding="UTF-8"%>
<%@ page contentType="text/html; charset=GBK" %>
<title>a.jpg</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<form name="add" method="post" action="AddServlet">
<table align="center" border="0" width="995">
<tr><td><%String n=request.getParameter("a");%>
String name = new String(n.getBytes("iso-8859-1"),"gb2312");</td>
<td><input type="text" name="name" value="<%=name%>"></td>
</tr>
</table>
</form>
servlet:
public void doGet(HttpServletRequest request, HttpServletResponse response)JSP Servlet
throws ServletException, IOException {
response.setContentType("text/html; charset=GBK");
request.setCharacterEncoding("GBK");
Bean b=new Bean();
rb.setName(request.getParameter("name"));
…………
String b=request.getParameter("name");
response.sendRedirect("a.jsp?a="+b);
}
[解决办法]
Tomcat的配置文件中默认传输字符格式的问题。。

[解决办法]
servlet代码
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String b = request.getParameter("name");
byte[] bytes = b.getBytes("iso-8859-1");
String b1 = new String(bytes);
System.out.println(b1);
response.sendRedirect("/web_c/a.jsp?a="+b);
}
jsp代码
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

String name = request.getParameter("a");
byte[] b = name.getBytes("iso-8859-1");
name = new String(b);
%>
<form name="add" method="post" action="AddServlet">
<table align="center" border="0" width="995">
<tr>

</form>
</body>
</html>
[解决办法]
你的servlet里
response.setContentType("text/html; charset=GBK"); request.setCharacterEncoding("GBK");
而jsp页面
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
一个GBK一个UTF-8，改一致试试，都改为UTF-8
