使用mina框架傳輸對象實體

使用mina框架傳輸對象實體方法如下：

 

對像實體

public class TransDataEntity {
	private String md5;
	private String path;
	private String fromIP;
	private byte[] filedata;
	public String getMd5() {
		return md5;
	}
	public void setMd5(String md5) {
		this.md5 = md5;
	}
	public String getPath() {
		return path;
	}
	public void setPath(String path) {
		this.path = path;
	}
	public String getFromIP() {
		return fromIP;
	}
	public void setFromIP(String fromIP) {
		this.fromIP = fromIP;
	}
	public byte[] getFiledata() {
		return filedata;
	}
	public void setFiledata(byte[] filedata) {
		this.filedata = filedata;
	}

}

			samplMinaServerHandler = new ServerHandler();
		}
		return samplMinaServerHandler;
	}

	private ServerHandler() {
	}

	// 當連接後打開時觸發此方法，一般此方法與 sessionCreated 會被同時觸發
	public void sessionOpened(IoSession session) throws Exception {
	}

	public void sessionClosed(IoSession session) {
	}

	public void messageReceived(IoSession session, Object message) throws Exception {
		if (message instanceof TransDataEntity) {
			TransDataEntity text = (TransDataEntity) message;
			
			System.out.println("服務器接收到從客戶端的getFromIP：" + text.getFromIP());
			System.out.println("服務器接收到從客戶端的getMd5：" + text.getMd5());
			System.out.println("服務器接收到從客戶端的getPath：" + text.getPath());
			System.out.println("服務器接收到從客戶端的文件內容：" + new String(text.getFiledata(), "GBK"));

		}
	}

	public void exceptionCaught(IoSession arg0, Throwable arg1) throws Exception {

	}

	// 當消息傳送到客戶端後觸發
	public void messageSent(IoSession arg0, Object arg1) throws Exception {

	}

	// 當一個新客戶端連接後觸發此方法.
	public void sessionCreated(IoSession arg0) throws Exception {

	}

	// 當連接空閒時觸發此方法.
	public void sessionIdle(IoSession arg0, IdleStatus arg1) throws Exception {

	}
