   Framework. More than 50 implementations of the `FactoryBean` interface ship with Spring

  NOTE: In Spring documentation, "factory bean" refers to a bean that is configured in the
  Spring container and that creates objects through an
  <<beans-factory-class-instance-factory-method,instance>> or
  <<beans-factory-class-static-factory-method,static>> factory method. By contrast,
  `FactoryBean` (notice the capitalization) refers to a Spring-specific
  <<beans-factory-extension-factorybean, `FactoryBean`>> implementation class.
