本章中演示在Spring中整合Mina，为了整合到Spring，需要做以下几个步骤：

1. 设置IoHandler

<bean id="trapHandler" class="com.ashishpaliwal.udp.mina.server.ServerHandler">

2. 创建Filters并加入到Chain中

<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. 创建IoAcceptor

<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>

4. 在spring启动时加载该xml文件

public void initializeViaSpring() throws Exception {

    new ClassPathXmlApplicationContext("trapReceiverContext.xml");

}
