Java JAX-WS连接赢得'；t关闭，并在x条消息后停止消息传递

我对JAX-WS有点问题。我使用ActiveMQ作为妈妈和Spring。消息传递非常简单：一个jar应该向另一个jar发送一条包含一些数据的soap消息

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

我在sender_beans.xml中这样定义了客户端：

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

这是我的终点：

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

<jaxws:endpoint id="ManagerService" implementor="#ManagerServ"
    implementorClass="com.example.Service"
    address="jms://">
    <jaxws:features>
        <bean class="org.apache.cxf.transport.jms.JMSConfigFeature"
            p:jmsConfig-ref="jmsConfig-Manager" />
    </jaxws:features>
</jaxws:endpoint>
<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

因此，消息传递是有效的——但只有40次！（这是p:maxConcurrentConsumers的值）。我认为问题在于，每次发送一条消息时，都会创建一个新的消费者，但从未销毁。因此，在40条消息之后，无法创建新的消费者，并且消息停止工作。我必须重新启动完整的消息传递

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

我只能使用声明方式来解决这个问题，我的代码中从未从jms调用任何东西。

默认情况下，CachingConnectionFactory将缓存消息使用者和生产者。您可以通过将cacheConsumers和cacheProducers属性设置为“false”来禁用此功能

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

例如，对于您的Spring xml：

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

<bean id="jmsConnectionFactory"
class="org.springframework.jms.connection.CachingConnectionFactory">
   <property name="sessionCacheSize" value="40" />
   <property name="cacheConsumers" value="false" />
   <property name="targetConnectionFactory">
...

...

我最近遇到了一个问题，即在对使用者对象调用.close（）时，编程创建的消息使用者没有被销毁（我仍然可以在ActiveMQ管理控制台上看到活动的使用者）。cacheConsumers=false为我解决了这个问题

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>

此外，请阅读缓存和单连接工厂上的SpringAPI，以确保您使用的是适用于您的场景的正确API——它们提到了所有这些

<bean id="jmsConfig-Manager" class="org.apache.cxf.transport.jms.JMSConfiguration"
    p:connectionFactory-ref="jmsConnectionFactory"
    p:targetDestination="activemq:example.manager"
    p:pubSubDomain="true" p:maxConcurrentConsumers="40" p:deliveryMode="1"
    p:explicitQosEnabled="true" p:reconnectOnException="true" />

<bean id="jmsConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="sessionCacheSize" value="40" />

    <property name="targetConnectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL"

                value="tcp://localhost:61616?jms.useAsyncSend=true" />
        </bean>
    </property>
</bean>
