使用MINA框架搭建服务端步骤:
1、定义一个启动服务的类MinaServer,并实现接口ServletContextListener
2、定义一个处理业务逻辑的类MinaServerHandler,并继承类IoHandlerAdapter
类MinaServer代码如下:
import java.net.InetSocketAddress; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; import javax.servlet.http.HttpSessionEvent; import javax.servlet.http.HttpSessionListener; import org.apache.mina.core.session.IdleStatus; import org.apache.mina.filter.codec.ProtocolCodecFilter; import org.apache.mina.filter.codec.serialization.ObjectSerializationCodecFactory; import org.apache.mina.filter.executor.ExecutorFilter; import org.apache.mina.transport.socket.nio.NioSocketAcceptor; import com.utils.LogUtil; public class MinaServer implements ServletContextListener, HttpSessionListener { private static NioSocketAcceptor acceptor; private static final int port = 9999; private static final LogUtil logUtil = LogUtil.getLogUtil(MinaServer.class); // 停止MINA服务 public void contextDestroyed(ServletContextEvent sce) { try { MinaServer.acceptor.unbind(); MinaServer.acceptor.dispose(); logUtil.customLog("Mina服务停止..."); } catch (Exception e) { logUtil.customLog(e); } } // 启动MINA服务 public void contextInitialized(ServletContextEvent sce) { try { // 创建一个非阻塞的server端的Socket acceptor = new NioSocketAcceptor(); // 设置过滤器 acceptor.getFilterChain().addLast( "serverCodec", new ProtocolCodecFilter( new ObjectSerializationCodecFactory())); acceptor.getFilterChain().addLast("ServerFilter", new ExecutorFilter()); // 设置读取数据的缓冲区大小 acceptor.getSessionConfig().setReadBufferSize(1024*102400); // 读写通道10秒内无操作进入空闲状态 acceptor.getSessionConfig().setIdleTime(IdleStatus.BOTH_IDLE, 10); // 添加逻辑处理器 acceptor.setHandler(new MinaServerHandler()); // 绑定端口 try { acceptor.bind(new InetSocketAddress(port)); } catch (Exception e) { } logUtil.customLog("服务端启动成功... 端口号为:" + port); } catch (Exception e) { logUtil.customLog("服务端启动异常...."); } } public void sessionCreated(HttpSessionEvent arg0) { } public void sessionDestroyed(HttpSessionEvent arg0) { } }
import org.apache.mina.core.service.IoHandlerAdapter; import org.apache.mina.core.session.IdleStatus; import org.apache.mina.core.session.IoSession; import com.model.DeliverObject; import com.model.Orders; import com.model.Users; import com.service.GoodsService; import com.service.OrdersService; import com.service.UserService; import com.utils.GetBeanUtil; import com.utils.LogUtil; import com.utils.Params; public class MinaServerHandler extends IoHandlerAdapter { private static final LogUtil logUtil = LogUtil .getLogUtil(MinaServerHandler.class); @Override public void sessionCreated(IoSession session) throws Exception { logUtil.customLog("服务端与客户端创建连接..."); } @Override public void sessionOpened(IoSession session) throws Exception { logUtil.customLog("服务端与客户端连接打开..."); } @Override public void messageReceived(IoSession session, Object message) throws Exception { DeliverObject recvObj = (DeliverObject) message; int optionType = recvObj.getOptionType(); // 如果是登录操作 if (optionType == Params.LOGIN) { UserService userService = (UserService) GetBeanUtil .getBean("userService"); userService.doLogin(session, (Users) recvObj.getObj()); } else if (optionType == Params.REGISTER) { // 如果是注册操作 UserService userService = (UserService) GetBeanUtil .getBean("userService"); userService.doRegister(session, (Users) recvObj.getObj()); } else if (optionType == Params.UPDATEUSER) { // 如果是修改用户信息操作 UserService userService = (UserService) GetBeanUtil .getBean("userService"); userService.doUpdateUser(session, (Users) recvObj.getObj()); } else if (optionType == Params.SEARCHGOODS) { // 如果是搜索商品操作 GoodsService goodsService = (GoodsService) GetBeanUtil .getBean("goodsService"); goodsService.doSearchGoods(session, (String) recvObj.getObj()); } else if (optionType == Params.SUBMITORDERS) { // 如果是提交订单操作 OrdersService ordersService = (OrdersService) GetBeanUtil .getBean("ordersService"); ordersService.doSubmitOrders(session, (Orders) recvObj.getObj()); } else if (optionType == Params.SEARCHALLORDERS) { // 如果是查询所有订单操作 OrdersService ordersService = (OrdersService) GetBeanUtil .getBean("ordersService"); ordersService.doSearchAllOrders(session, (Users) recvObj.getObj()); } } @Override public void messageSent(IoSession session, Object message) throws Exception { logUtil.customLog("服务端发送信息成功..."); } @Override public void sessionClosed(IoSession session) throws Exception { logUtil.customLog("服务端与客户端连接关闭..."); session.close(true); } @Override public void sessionIdle(IoSession session, IdleStatus status) throws Exception { super.sessionIdle(session, status); logUtil.customLog("服务端进入空闲状态..."); } @Override public void exceptionCaught(IoSession session, Throwable cause) throws Exception { logUtil.customLog("服务端发送异常..." + cause); session.close(true); } }
