          org.springframework.context.support.ResourceMapFactoryBean

All Implemented Interfaces:

FactoryBean, InitializingBean, ResourceLoaderAware

public class ResourceMapFactoryBean

extends PropertiesFactoryBean

implements ResourceLoaderAware

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.

Method Detail

setResourceBasePath

public void setResourceBasePath(String resourceBasePath)

Set a base path to prepend to each resource location value in the properties file.

E.g.: resourceBasePath="/images", value="/test.gif" -> location="/images/test.gif"

setResourceLoader

public void setResourceLoader(ResourceLoader resourceLoader)

Description copied from interface: ResourceLoaderAware

Set the ResourceLoader that this object runs in.

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.

Specified by:

setResourceLoader in interface ResourceLoaderAware

Parameters:

resourceLoader - ResourceLoader object to be used by this object

getObjectType

public Class getObjectType()

Description copied from interface: FactoryBean

Return the type of object that this FactoryBean creates, or null if not known in advance. This allows to check for specific types of beans without instantiating objects, for example on autowiring.

For a singleton, this 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.

Specified by:

getObjectType in interface FactoryBean

Overrides:

getObjectType in class PropertiesFactoryBean

createInstance

protected Object createInstance()
                         throws Exception

Description copied from class: AbstractFactoryBean

Template method that subclasses must override to construct the object returned by this factory.

Invoked on initialization of this FactoryBean in case of a singleton; else, on each getObject() call.

Overrides:

createInstance in class PropertiesFactoryBean

Throws:

Exception
