Xsocket学习

1.xsocket是一个轻量级的基于NIO的服务器框架，用于开发高性能、可扩展、多线程的服务器。该框架封装了线程处理，异步读写等方面的操作。

　　定义一个借口，继承IDataHandler,IConnectExceptionHandler, IConnectHandler, IDisconnectHandler：

public interface SocketDataHander extends IDataHandler,
    IConnectExceptionHandler, IConnectHandler, IDisconnectHandler{

}

　　写出这个接口的实现方法：

　

public class SocketUnionPay implements SocketDataHander{

    
    @Override
    public boolean onData(INonBlockingConnection connection) throws IOException,
            BufferUnderflowException, ClosedChannelException,
            MaxReadSizeExceededException {
        // TODO Auto-generated method stub
        start = System.currentTimeMillis();//获取当前时间
        byte[] data = connection.readBytesByLength(connection.available());  //监控接收到的数据
        
        //接收数据，转换为输出流，并且输出
        receiveBufByte = new Iso8583_Send_OutputStream(null);
        receiveBufByte.write(data, 0, data.length);
        System.out.println("##############################长度:"+data.length);
        
        if(receiveBufByte.length() > 9){
            LOG.info("接收数据:" + new String(receiveBufByte.getBufbyte()) + "  长度:" + receiveBufByte.length());
            
            byte[] sendata = unionPay_processingCentre.sendTreatmentTrade(receiveBufByte.getBufbyte());  //处理发送并返回
            byte[] rendata = unionPay_processingCentre.respTreatmentTrade(sendata);//数据返回处理
            LOG.info("返回数据:" + new String(rendata));
            connection.write(rendata);
        }
        
        end = System.currentTimeMillis();
        if(LOG.isTraceEnabled()){
            LOG.trace("########################前置处理耗时:"+(end-start)+"#######################");
        }
        return true;
    }

    @Override
    public boolean onConnectException(INonBlockingConnection connection,
            IOException e) throws IOException {
        // TODO Auto-generated method stub
        LOG.error("转发Bank连接异常..onConnectException...");
        return true;
    }

    @Override
    public boolean onConnect(INonBlockingConnection connection) throws IOException,
            BufferUnderflowException, MaxReadSizeExceededException {
        // TODO Auto-generated method stub
        LOG.info("Scoket前置打开连接..onConnect...");
        return true;
    }

    @Override
    public boolean onDisconnect(INonBlockingConnection connection) throws IOException {
        // TODO Auto-generated method stub
        LOG.info("Scoket前置关闭连接..onDisconnect...");
        connection.close();
        return true;
    }

}
