/**
*
* A {@link FactoryBean FactoryBean} for creating an
* {@link SpringRemoteCacheManager
* SpringRemoteCacheManager} instance.
*
* Configuration
*
* A SpringRemoteCacheManager is configured through a {@link Properties
* Properties} object. For an exhaustive list of valid properties to be used see
* RemoteCacheManager's {@link RemoteCacheManager
* javadocs}. This FactoryBean provides means to either
* {@link #setConfigurationProperties(Properties) inject} a user-defined Properties
* instance or to
* {@link #setConfigurationPropertiesFileLocation(org.springframework.core.io.Resource) set} the
* location of a properties file to load those properties from. Note that it is illegal to
* use both mechanisms simultaneously.
*
*
* Alternatively or in combination with
* {@link #setConfigurationPropertiesFileLocation(org.springframework.core.io.Resource) setting} the
* location of a Properties file to load the configuration from, this
* FactoryBean provides (typed) setters for all configuration settings. Settings thus
* defined take precedence over those defined in the injected Properties instance. This
* flexibility enables users to use e.g. a company-wide Properties file containing
* default settings while simultaneously overriding select settings whenever special requirements
* warrant this.
* Note that it is illegal to use setters in conjunction with
* {@link #setConfigurationProperties(Properties) injecting} a Properties instance.
*
*
* In addition to creating a SpringRemoteCacheManager this FactoryBean
* does also control that SpringRemoteCacheManager's 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 SpringRemoteCacheManager.
