FactoryBean that creates a bean and populates its properties with values from the repository and reloads the bean automatically when the repository is updated. The returned instance is a proxy that delegates calls to the instance created from the repository. The instance delegated to is transparently swapped. The proxy is by default a JDK dynamic proxy proxying all the objects interfaces. This can be changed to a cglib proxy by setting the property proxyTargetClass to true. There is a delay mechanism in place that aggregates events in order to postpone reloading while the repository is being updated. By default any change postpones reloading by 15 seconds but no longer than 60 seconds. These values can be configured.
