带有Spring Bean的MDB不会自动将另一个软件包中的Bean接线

Question

I am using following MDB to connect to WMQ:

@MessageDriven(name = "EventListener", activationConfig = {
   @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
   @ActivationConfigProperty(propertyName = "destination", propertyValue = "ABC"),
   @ActivationConfigProperty(propertyName = "hostName", propertyValue = "ABC"),
   @ActivationConfigProperty(propertyName = "port", propertyValue = "ABC"),
   @ActivationConfigProperty(propertyName = "channel", propertyValue = "ABC"),
   @ActivationConfigProperty(propertyName = "queueManager", propertyValue = "ABC"),
   @ActivationConfigProperty(propertyName = "sslCipherSuite", propertyValue = "ABC"),
   @ActivationConfigProperty(propertyName = "transportType", propertyValue = "CLIENT") })
@ResourceAdapter(value = "wmq.jmsra.rar")
@TransactionManagement(value = TransactionManagementType.CONTAINER)
@TransactionAttribute(value = TransactionAttributeType.REQUIRED)
@Interceptors(SpringBeanAutowiringInterceptor.class)
public class EventListener implements MessageListener {}

Following spring beans are being autowired as part of the interceptor annotation used in the above MDB. event-app-config.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/jee

    <context:component-scan base-package="com.abc" />
    <context:annotation-config/>
    <import resource="classpath:core-app-config.xml" /> //This is another package

</beans>

Following is the core-app-config.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"

    <import resource="classpath:database-config.xml" />
    <import resource="classpath:spring-jms-config.xml" />

</beans>

Main xml beanRefContext.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"

    http://www.springframework.org/schema/context/spring-context.xsd">

     <context:annotation-config/>
     <context:spring-configured/>

     <bean id="beanRefFactory" class="org.springframework.context.support.ClassPathXmlApplicationContext">
         <constructor-arg value="classpath*:event-app-config.xml"  />
     </bean>              
</beans>

I am autowiring certain bean instances from database & spring jms xmls in the MDB package but looks like all the beans inside these xmls are not created. Can you please understand what can be the issue. Does the autowire functionality of the MDB restricted to the spring xmls in the same package and any other imports being done inside parent spring bean xml is not created?

Example: EventListener is in com.abc.xyz package. I am autowiring instance of class A from com.abc.core package in eventlistener class. Class A is @Service and that in turn has autowired dependency say Class B which in com.abc.packB . So when the instance of class A is created I get an exception saying that no Class B definition is found.

To solve this problem you need to use SpringBeanAutowiringSupport .

Because MDB created not in Spring context, you must autowire beans that you need with SpringBeanAutowiringSupportprocessInjectionBasedOnCurrentContext(Object target) method or inherit MDB from SpringBeanAutowiringSupport .
