If you configure a bean with an `MBeanExporter` that is also configured for lazy
initialization, the `MBeanExporter` does not break this contract and avoids
instantiating the bean. Instead, it registers a proxy with the `MBeanServer` and
defers obtaining the bean from the container until the first invocation on the proxy
occurs.
instantiating the bean. Instead, it registers a proxy with the `MBeanServer` and defers
obtaining the bean from the container until the first invocation on the proxy occurs.
This also affects `FactoryBean` resolution where `MBeanExporter` will regularly
introspect the produced object, effectively triggering `FactoryBean.getObject()`.
In order to avoid this, mark the corresponding bean definition as lazy-init.

== Automatic Registration of MBeans
Any beans that are exported through the `MBeanExporter` and are already valid MBeans are
registered as-is with the `MBeanServer` without further intervention from Spring. You can cause MBeans
to be automatically detected by the `MBeanExporter` by setting the `autodetect`
property to `true`, as the following example shows:
