flex - java 数据传输

==java端写入数据

SerializationContext serializationContext=new SerializationContext();

Amf3Output amfOut = new Amf3Output(serializationContext);

ByteArrayOutputStream outStream = new ByteArrayOutputStream();

DataOutputStream dataOutStream = new DataOutputStream(outStream);

amfOut.setOutputStream(dataOutStream);
//HashMap

Map map = new HashMap();

String[] arr = "1,2,3,4,5".split(",");

map.put("datas", arr);

map.put("name","kinglong");

map.put("age", "金龙工作室");

map.put("domain", "klstudio.com");

try {

amfOut.writeObject(map);

} catch (IOException e1) {

e1.printStackTrace();

}

byte[] messageBytes = outStream.toByteArray();

try

{

FileOutputStream os;

OutputStreamWriter ow;

BufferedWriter out;

os = new FileOutputStream("D://test.txt");

ow = new OutputStreamWriter(os);

out = new BufferedWriter(ow);

os.write(messageBytes);

os.flush();

os.close();

System.out.println("OK");

}catch(Exception e)

{

System.out.println("error :" + e);

}

==flex 端读取数据
