一個mina應用主要包括一下方面：

• One Handler
• Two Filter - Logging Filter and a ProtocolCodec Filter
• NioDatagram Socket

一個mina 服務端的實例程序如下：

public void initialize() throws IOException {// Create an AcceptorNioDatagramAcceptor acceptor = new NioDatagramAcceptor();// Add Handleracceptor.setHandler(new ServerHandler());acceptor.getFilterChain().addLast("logging",new LoggingFilter());acceptor.getFilterChain().addLast("codec",new ProtocolCodecFilter(new SNMPCodecFactory()));// Create Session ConfigurationDatagramSessionConfig dcfg = acceptor.getSessionConfig();dcfg.setReuseAddress(true);logger.debug("Starting Server......");// Bind and be ready to listenacceptor.bind(new InetSocketAddress(DEFAULT_PORT));logger.debug("Server listening on "+DEFAULT_PORT); }

繼承過程如下：

1.設置IO handler。在spring context文件中設置IO handler。

<!-- The IoHandler implementation --> <bean id="trapHandler" class="com.ashishpaliwal.udp.mina.server.ServerHandler">

2.創建過濾器鏈。

<bean id="snmpCodecFilter" class="org.apache.mina.filter.codec.ProtocolCodecFilter"><constructor-arg><bean class="com.ashishpaliwal.udp.mina.snmp.SNMPCodecFactory" /></constructor-arg> </bean><bean id="loggingFilter" class="org.apache.mina.filter.logging.LoggingFilter" /><!-- The filter chain. --> <bean id="filterChainBuilder" class="org.apache.mina.core.filterchain.DefaultIoFilterChainBuilder"><property name="filters"><map><entry key="loggingFilter" value-ref="loggingFilter"/><entry key="codecFilter" value-ref="snmpCodecFilter"/></map></property> </bean>

3.創建socket并設置socket參數

<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="java.net.SocketAddress"><bean class="org.apache.mina.integration.beans.InetSocketAddressEditor" /></entry></map></property> </bean><!-- The IoAcceptor which binds to port 161 --> <bean id="ioAcceptor" class="org.apache.mina.transport.socket.nio.NioDatagramAcceptor" init-method="bind" destroy-method="unbind"><property name="defaultLocalAddress" value=":161" /><property name="handler" ref="trapHandler" /><property name="filterChainBuilder" ref="filterChainBuilder" /> </bean>

測試程序

public void initializeViaSpring() throws Exception {new ClassPathXmlApplicationContext("trapReceiverContext.xml"); }
