## Uses of InitializingBean in org.springframework.beans.factory.config

Classes in org.springframework.beans.factory.config that implement InitializingBean
Modifier and Type
Class
Description
`class`
`AbstractFactoryBean<T>`
Simple template superclass for `FactoryBean` implementations that creates a singleton or a prototype object, depending on a flag.
`class`
`FieldRetrievingFactoryBean`
`FactoryBean` which retrieves a static or non-static field value.
`class`
`ListFactoryBean`
Simple factory for shared List instances.
`class`
`MapFactoryBean`
Simple factory for shared Map instances.
`class`
`MethodInvokingBean`
Simple method invoker bean: just invoking a target method, not expecting a result to expose to the container (in contrast to `MethodInvokingFactoryBean`).
`class`
`MethodInvokingFactoryBean`
`FactoryBean` which returns a value which is the result of a static or instance method invocation.
`class`
`ObjectFactoryCreatingFactoryBean`
A `FactoryBean` implementation that returns a value which is an `ObjectFactory` that in turn returns a bean sourced from a `BeanFactory`.
`class`
`PreferencesPlaceholderConfigurer`
Deprecated.
as of 5.2, along with `PropertyPlaceholderConfigurer`
`class`
`PropertiesFactoryBean`
Allows for making a properties file from a classpath location available as Properties instance in a bean factory.
`class`
`ProviderCreatingFactoryBean`
A `FactoryBean` implementation that returns a value which is a JSR-330 `Provider` that in turn returns a bean sourced from a `BeanFactory`.
`class`
`ServiceLocatorFactoryBean`
A `FactoryBean` implementation that takes an interface which must have one or more methods with the signatures `MyType xxx()` or `MyType xxx(MyIdType id)` (typically, `MyService getService()` or `MyService getService(String id)`) and creates a dynamic proxy which implements that interface, delegating to an underlying `BeanFactory`.
`class`
`SetFactoryBean`
Simple factory for shared Set instances.
`class`
`YamlMapFactoryBean`
Factory for a `Map` that reads from a YAML source, preserving the YAML-declared value types and their structure.
`class`
`YamlPropertiesFactoryBean`
Factory for `Properties` that reads from a YAML source, exposing a flat structure of String property values.

## Uses of InitializingBean in org.springframework.beans.factory.serviceloader

Modifier and Type
Class
Description
`class`
`AbstractServiceLoaderBasedFactoryBean`
Abstract base class for FactoryBeans operating on the JDK 1.6 `ServiceLoader` facility.
`class`
`ServiceFactoryBean`
`FactoryBean` that exposes the 'primary' service for the configured service class, obtained through the JDK 1.6 `ServiceLoader` facility.
`class`
`ServiceListFactoryBean`
`FactoryBean` that exposes all services for the configured service class, represented as a List of service objects, obtained through the JDK 1.6 `ServiceLoader` facility.
`class`
`ServiceLoaderFactoryBean`
`FactoryBean` that exposes the JDK 1.6 `ServiceLoader` for the configured service class.

Convenient base class for bean configurers that can perform Dependency Injection on objects (however they may be created).
