mina简介：
名井南（Mina），1997年3月24日出生于美国德州圣安东尼奥，日本女歌手，韩国女子演唱组合TWICE成员。
一 下载mina 的jar包
我下载的是mina-core-2.0.16.jar和slf4j-android-1.6.1-RC1.jar
二 服务端
1.启动服务，等待客户端连接：主要使用的类：NioSocketConnector
public class MinaService {
private NioSocketAcceptoracceptor =null;
public void main() {
Log.i(BaseApp.TAG,"尝试启动服务器 ...: ");
// 继承IoService，服务器端接收器
if (acceptor ==null) {
acceptor =new NioSocketAcceptor();
// 添加过滤器
acceptor.getFilterChain().addLast("日志过滤器",new LoggingFilter());// 日志过滤器
acceptor.getFilterChain().addLast("只能传输序列化后的对象",new ProtocolCodecFilter(new ObjectSerializationCodecFactory()));// 只能传输序列化后的对象
acceptor.getFilterChain().addLast("threadPool",new ExecutorFilter(Executors.newCachedThreadPool()));
// 进行一些初始化配置
acceptor.getSessionConfig().setReadBufferSize(2048*2);// 设置读缓存区大小
acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE,10);// 如果10秒钟没有任何读写，就设置成空闲状态。 BOTH_IDLE（读和写）
//设置Handler回调
acceptor.setHandler(new MyHandler());
}
// 设置监听端口号，开始监听了
try {
acceptor.bind(new InetSocketAddress(PORT));
Log.i(BaseApp.TAG,"启动成功: ");
}catch (Exception e) {
Log.i(BaseApp.TAG,"失败: "+e.getMessage());
e.printStackTrace();
}
}
}
2.MinaHandler 回调
public class MyHandler extends IoHandlerAdapter {
@Override
public void exceptionCaught(IoSession session, Throwable cause)throws Exception {
super.exceptionCaught(session, cause);
Log.i(BaseApp.TAG,"exceptionCaught: ");
}
@Override
public void inputClosed(IoSession session)throws Exception {
super.inputClosed(session);
Log.i(BaseApp.TAG,"inputClosed: ");
}
@Override
public void sessionIdle(IoSession session, IdleStatus status)throws Exception {
super.sessionIdle(session, status);
Log.i(BaseApp.TAG,"sessionIdle: ");
}
// session创建时回调
public void sessionCreated(IoSession session)throws Exception {
super.sessionCreated(session);
SessionManager.getInstance().setSession(session);
Log.i(BaseApp.TAG,"sessionCreated " );
}
// session打开时回调
public void sessionOpened(IoSession session)throws Exception {
super.sessionOpened(session);
Log.i(BaseApp.TAG,"sessionOpened " );
}
// 消息接收时回调
public void messageReceived(IoSession session, Object message)throws Exception {
super.messageReceived(session, message);
Log.i(BaseApp.TAG,"messageReceived: 接收到消息 = "+message );
SessionManager.getInstance().upData(message+"");
}
// 消息发送时回调
public void messageSent(IoSession session, Object message)throws Exception {
super.messageSent(session, message);
Log.i(BaseApp.TAG,"messageSent发送消息到服务端 = "+message );
}
// session关闭时回调
public void sessionClosed(IoSession session)throws Exception {
super.sessionClosed(session);
Log.i(BaseApp.TAG,"sessionClosed: 关闭session");
}
}
3.单例SessionManager ,setHanler() 需要在主页MainActivity写一个Handler并且设置过来 方便数据传递
public class SessionManager {
private IoSessionsession;
private static SessionManagerinstance =null;
private SessionManager(){
}
public static SessionManager getInstance() {
if (instance ==null) {
synchronized (SessionManager.class) {
if (instance ==null) {
instance =new SessionManager();
}
}
}
return instance;
}
public IoSession getSession() {
return session;
}
public void setSession(IoSession session) {
this.session = session;
}
private Handlerhandler;
public void setHandler(Handler handler){
this.handler = handler;
}
public void upData(String msg) {
Message message =new Message();
message.obj = msg;
handler.sendMessage(message);
}
/**
* 写消息
* */
public void writeMag(String msg){
if(session !=null){
session.write(msg);
}
}
/**
* 关闭
* */
public void closeSession(){
if(session !=null){
session.closeOnFlush();
session =null;
}
}
}
三：客户端
1.连接服务端
public class MinaConnectManager {
private static final StringTAG ="MinaConnectManager";
private NioSocketConnectorsocketConnector;
public MinaConnectManager() {
init();
}
private void init() {
socketConnector =new NioSocketConnector();
// 添加过滤器
socketConnector.getFilterChain().addLast("日志过滤器",new LoggingFilter());// 日志过滤器
socketConnector.getFilterChain().addLast("只能传输序列化后的对象",new ProtocolCodecFilter(new ObjectSerializationCodecFactory()));// 只能传输序列化后的对象
//超时时间
socketConnector.setConnectTimeoutMillis(5000);
// 回调的handler
socketConnector.setHandler(new MinaHandler());
// 进行一些初始化配置
socketConnector.getSessionConfig().setReadBufferSize(2048*2);// 设置读缓存区大小
// 设置IP地址
SocketAddress mAddress =new InetSocketAddress(LOCAL,PORT);
socketConnector.setDefaultRemoteAddress(mAddress);
}
public boolean connect() {
Log.i(TAG,"尝试连接: "+LOCAL);
try {
ConnectFuture connectFuture =socketConnector.connect();//查询连接状态
connectFuture.awaitUninterruptibly();
IoSession mSession = connectFuture.getSession();
SessionManager.getInstance().setSession(mSession);//单例拿到实例用于发送消息
Log.i(TAG,"连接成功: ");
return true;
}catch (Exception e) {
Log.i(TAG,"连接失败: "+e.getMessage());
e.printStackTrace();
return false;
}
}
}
2.Handler回调
public class MinaHandlerextends IoHandlerAdapter {
private static final StringTAG ="MinaHandler";
// session打开时回调
public void sessionOpened(IoSession session)throws Exception {
super.sessionOpened(session);
Log.i(TAG,"sessionClosed: 连接打开");
}
@Override
public void sessionClosed(IoSession session)throws Exception {
super.sessionClosed(session);
Log.i(TAG,"sessionClosed: 连接断开");
SessionManager.getInstance().upData("", Constants.CONNECT_ERR);
}
// 消息接收时回调
public void messageReceived(IoSession session, Object message)throws Exception {
super.messageReceived(session, message);
Log.i(TAG,"messageReceived: 接收到消息");
SessionManager.getInstance().upData(message+"", Constants.DEVICE_MSG);
}
// 消息发送时回调
public void messageSent(IoSession session, Object message)throws Exception {
super.messageSent(session, message);
Log.i(TAG,"messageSent: 发送消息成功");
}
@Override
public void sessionIdle(IoSession session, IdleStatus status)throws Exception {
super.sessionIdle(session, status);
Log.i(TAG,"sessionIdle: 服务端空闲时间");
}
}
3.单例SessionManager 消息发送
public class SessionManager {
private IoSessionsession;
private volatile static SessionManagerinstance =null;
private SessionManager(){
}
public static SessionManager getInstance() {
if (instance ==null) {
synchronized (SessionManager.class) {
if (instance ==null) {
instance =new SessionManager();
}
}
}
return instance;
}
private Handlerhandler;
public void setHandler(Handler handler){
this.handler = handler;
}
public void upData(String msg,int what) {
Message message =new Message();
message.obj = msg;
message.what = what;
handler.sendMessage(message);
}
public IoSession getSession() {
return session;
}
public void setSession(IoSession session) {
this.session = session;
}
/**
* 写消息
* */
public void writeMag(String msg){
if(session !=null){
session.write(msg);
}
}
/**
* 关闭
* */
public void closeSession(){
if(session !=null){
session.closeOnFlush();
session =null;
}
}
}
四：注释基本都是有的，就不详细介绍了，百度很多介绍，客户端，服务端两边代码基本一样 只是一个启动服务等待连接 一个连接服务，代码基本就这么多，从项目重复制出来的，应该不差其它东西。
