Here's what you need to do:
Put this anywhere in your Spring config
<bean id="org.apache.mina.common.ThreadModel.MANUAL"
class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"/>
When you configure your SocketAcceptorConfig be sure to set the
threadModel to MANUAL otherwise MINA will create a ThreadPoolFilter for you
<bean class="org.apache.mina.transport.socket.nio.SocketAcceptorConfig">
<property name="reuseAddress" value="true"/>
<property name="threadModel"
ref="org.apache.mina.common.ThreadModel.MANUAL"/>
</bean>
Then you need to change your XML above into
<bean class="org.apache.mina.filter.thread.ThreadPoolFilter">
<constructor-arg>
<bean class="org.apache.mina.filter.thread.LeaderFollowersThreadPool">
<!-- Threads will be named IoWorker-1, IoWorker-2, etc -->
<constructor-arg value="IoWorker"/>
<property name="maximumPoolSize" value="16"/>
<property name="keepAliveTime" value="60000"/>
</bean>
</constructor-arg>
An alternative to the changes above would be to configure your own
PooledThreadModel and remove the ThreadPoolFilter configuration:
<bean class="org.apache.mina.transport.socket.nio.SocketAcceptorConfig">
<property name="reuseAddress" value="true"/>
<property name="threadModel">
<bean class="org.apache.mina.common.PooledThreadModel">
<property name="threadNamePrefix" value="IoWorker"/>
<property name="maximumPoolSize" value="16"/>
<property name="keepAliveTime" value="60000"/>
</bean>
</property>
</bean>
Thanks for bringing this to my attention. I have updated the Javadoc for
IoAcceptorFactoryBean.
I think I will have to look into how we can simplify the Spring
integration further. With the introduction of ThreadModel and the
generalization of ThreadPoolFilter the Spring integration has been a lot
more complicated.
