/**
*
* A {@link org.springframework.beans.factory.FactoryBean FactoryBean} for creating an
* {@link org.infinispan.spring.provider.SpringEmbeddedCacheManager
* SpringEmbeddedCacheManager} instance. The location of the Infinispan configuration
* file used to provide the default {@link org.infinispan.configuration.cache.Configuration configuration} for
* the EmbeddedCacheManager instance created by this FactoryBean is
* {@link #setConfigurationFileLocation(org.springframework.core.io.Resource) configurable}.
*
*
* If no configuration file location is set the SpringEmbeddedCacheManager instance
* created by this FactoryBean will use Infinispan's default settings. See Infinispan's
* documentation for what those default settings
* are.
*
*
* A user may further customize the SpringEmbeddedCacheManager's configuration using
* explicit setters on this FactoryBean. The properties thus defined will be applied
* either to the configuration loaded from Infinispan's configuration file in case one has been
* specified, or to a configuration initialized with Infinispan's default settings. Either way, the
* net effect is that explicitly set configuration properties take precedence over both those loaded
* from a configuration file as well as INFINISPAN's default settings.
*
*
* In addition to creating an SpringEmbeddedCacheManager this FactoryBean
* does also control that SpringEmbeddedCacheManager's
* {@link org.infinispan.commons.api.Lifecycle lifecycle} by shutting it down when the enclosing
* Spring application context is closed. It is therefore advisable to always use this
* FactoryBean when creating an SpringEmbeddedCacheManager.
