Auto-Detecting MBeans by Annotations
In addition to exporting a bean explicitly with MBeanExporter , you can simply configure its subclass
AnnotationMBeanExporter to auto-detect MBeans from beans declared in the IoC container. You needn't
configure an MBean assembler for this exporter because it uses MetadataMBeanInfoAssembler with
AnnotationJmxAttributeSource by default. You can delete the previous beans and assembler properties
for this exporter.

<bean id="mbeanExporter"
class="org.springframework.jmx.export. annotation.AnnotationMBeanExporter">
...
</bean>

AnnotationMBeanExporter detects any beans configured in the IoC container with the
@ManagedResource annotation and exports them as MBeans. By default, this exporter exports a bean to
the domain whose name is the same as its package name. Also, it uses the bean's name in the IoC
container as its MBean name, and the bean's short class name as its type. So your documentReplicator
bean will be exported under the following MBean object name:

com.apress.springenterpriserecipes.replicator:name=documentReplicator,

➥

type=FileReplicatorJMXImpl

If you don't want to use the package name as the domain name, you can set the default domain for
this exporter.

<bean id="mbeanExporter"
class="org.springframework.jmx.export.annotation.AnnotationMBeanExporter">
...
<property name="defaultDomain" value="bean" />
</bean>
