flex交互编码，解决乱码问题

?1.Flex端传到Java端
?
Flex端:encodeURIComponent(comment.text)
使用encodeURIComponent把参数转换为 application/x-www-form-urlencoded 格式
?
Java端:URLDecoder.decode(comment, "utf-8")
对 x-www-form-urlencoded 字符串解码
?
2.Java端传到Flex端
?
HttpServletResponse response = ServletActionContext.getResponse();
PrintWriter out = response.getWriter();
response.setContentType("text/html;charset=utf-8");

out.println(doc.asXML());
out.flush();
out.close();

→

HttpServletResponse response = ServletActionContext.getResponse();
ServletOutputStream out = response.getOutputStream();
response.setContentType("text/html;charset=utf-8");

out.write(doc.asXML().getBytes("UTF-8"));
out.flush();
out.close();??
