response.setContentType("text/csv; charset=UTF-8");
response.setHeader ("Pragma", "public");
response.setHeader ("Cache-Control", "must-revalidate");
response.setDateHeader ("Expires",0);
response.setHeader("Content-disposition","attachment; filename=contacts.csv");

PrintWriter out = response.getWriter();

AuthProfile auth = (AuthProfile)request.getSession().getAttribute("auth");
ArrayList result = ImportExportController.exportContacts(auth);
if (result != null) {
for (int i=0;i<result.size();i++) {
out.write((String)result.get(i) + "\n");
System.out.println(result.get(i));
}
}

}

将
response.setContentType("text/csv; charset=UTF-8");
改为
response.setContentType("text/html; charset=GB2312");

在最前面加个 request.setContentType("gbk");
用来转换 得到的 参数的 编码类型
必须是最前面
