Flex和Java交互的乱码解决方案
今天做Flex时碰到flex和java交互的乱码问题，使用HTTPService无论是从Flex端传到Java端，还是反过来都乱码。调查了半天，终于搞定了。
以下是解决方案：
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();

文中引用了孙老师的代码，并注明。
import java.io.*;
import java.net.*;
public class EchoServer {
private int port=8888;
private ServerSocket serverSocket;
public EchoServer() throws IOException {
serverSocket = new ServerSocket(port);
System.out.println("服务器启动");

1.servlet产生验证码：
package com.servlet;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.util.Random;
import javax.imageio.ImageIO; ......
