public class ResourceMapFactoryBean
FactoryBean that creates a Map with String keys and Resource values from properties, interpreting passed-in String values as resource locations.
Extends PropertiesFactoryBean to inherit the capability of defining local properties and loading from properties files.
Implements the ResourceLoaderAware interface to automatically use the context ResourceLoader if running in an ApplicationContext. Uses DefaultResourceLoader else.

ResourceLoaderAware
This might be a ResourcePatternResolver, which can be checked
through instanceof ResourcePatternResolver
. See also the
ResourcePatternUtils.getResourcePatternResolver
method.
Invoked after population of normal bean properties but before an init callback
like InitializingBean's afterPropertiesSet
or a custom init-method.
Invoked before ApplicationContextAware's setApplicationContext
.

public Class getObjectType()
FactoryBean
null
if not known in advance.
This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return
null
here. Therefore it is highly recommended to implement
this method properly, using the current state of the FactoryBean.
