spring mina整合(客户端进行调用)

1.需要的包

mina-core-2.0.4.jar
mina-integration-beans-2.0.4.jar
org.springframework.beans-3.0.5.RELEASE.jar
org.springframework.web-3.0.5.RELEASE.jar
org.springframework.context-3.0.5.RELEASE.jar
org.springframework.core-3.0.5.RELEASE.jar
commons-logging-1.1.jar
org.springframework.asm-3.0.5.RELEASE.jar
org.springframework.expression-3.0.5.RELEASE.jar
slf4j-log4j12-1.5.8.jar
slf4j-api-1.5.8.jar
log4j-1.2.14.jar

2.新建SpringMina web 项目，先看下我的目录：

3.在web.xml中配置如下信息：

   contextConfigLocation
    
    
     classpath:/config/spring/applicationContext-mina.xml
    
   
  
    org.springframework.web.context.ContextLoaderListener
 
 
 
 
  encodingFilter
  org.springframework.web.filter.CharacterEncodingFilter
  
   encoding
   UTF-8
  
  
   forceEncoding
   true
  
 
 
 
  encodingFilter
  /*
 

4.新建Source folder名为config，新建包名为config.spring,在此报下面建applicationContext-mina.xml文件，内容如下(头文件要加上)：

  
   
  
 
 
 
 
 
 
 
 
 
  
 
 
 
  
   
  
 
 
 
 
 
    class="org.apache.mina.core.filterchain.DefaultIoFilterChainBuilder">
  
   
  
 
 
 
    init-method="bind" destroy-method="unbind">
  
  
  
  
 

6.新建包名com.sk.mina，新建MinaProtocolHandler类(服务端应用程序)，并且继承IoHandlerAdapter类，内容如下：

private final Logger logger = LoggerFactory.getLogger(getClass());

 public void messageReceived(IoSession session, Object message) {
  String msg = (String) message;
  System.out.println("Server Received: " + msg);
  session.write("Server Send: " + msg);
  //sessions.add(session);
 }

 @SuppressWarnings("deprecation")
 public void sessionIdle(IoSession session, IdleStatus status) {
  //disconnect an idle client
  session.close();
 }

 @SuppressWarnings("deprecation")
 public void exceptionCaught(IoSession session, Throwable cause) {
  logger.warn("Unexpected exception.", cause);
  session.close();
 }

7.新建MinaClientHandler类(用来处理服务端发过来的信息)，并继承IoHandlerAdapter类，内容如下：

private static final IoFilter LOGGING_FILTER = new LoggingFilter();

 private static final IoFilter CODEC_FILTER = new ProtocolCodecFilter(
   new TextLineCodecFactory());

 @Override
 public void sessionCreated(IoSession session) throws Exception {
  session.getFilterChain().addLast("codec", CODEC_FILTER);
  session.getFilterChain().addLast("logger", LOGGING_FILTER);
 }

 @Override
 public void messageReceived(IoSession session, Object message)
   throws Exception {
  String msg = (String) message;
  System.out.println("Client Received: " + msg);
 }

8.新建MinaClientSupport类(负责发送客户端的请求到服务器端),内容如下：

private IoHandler handler = null;

 private IoSession session;

 private String host;

 private int port;

 public boolean send(Object message) {
  if (session != null && session.isConnected()) {
   throw new IllegalStateException(
     "Already connected. Disconnect first.");
  }
  SocketAddress address = new InetSocketAddress(host, port);
  NioSocketConnector connector = new NioSocketConnector();
  try {

   connector.getFilterChain().addLast("mdc", new MdcInjectionFilter());

   connector.setHandler(handler);
   ConnectFuture future1 = connector.connect(address);
   future1.awaitUninterruptibly();
   if (!future1.isConnected()) {
    return false;
   }
   session = future1.getSession();
   session.write(message);
   return true;
  } catch (Exception e) {
   return false;
  }
 }

 @SuppressWarnings("deprecation")
 public void close() {
  if (session != null) {
   if (session.isConnected()) {
    session.getCloseFuture().awaitUninterruptibly();
   }
   session.close();
  }
 }

 public String getHost() {
  return host;
 }

 public void setHost(String host) {
  this.host = host;
 }

 public int getPort() {
  return port;
 }

 public void setPort(int port) {
  this.port = port;
 }

 public void setHandler(IoHandler handler) {
  this.handler = handler;
 }

 public static void main(String[] args) {
  System.out.println("---------------------");
  MinaClientSupport client = new MinaClientSupport();
  MinaClientHandler handler = new MinaClientHandler();
  client.setHandler(handler);
  client.setHost("127.0.0.1");
  client.setPort(1235);
  String msg = "hello world!";
  client.send(msg);
  System.out.println("Client Send: " + msg);
  client.close();
 }
