Class EntityManagerFactoryBuilder

java.lang.Object

org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder

public class EntityManagerFactoryBuilder
extends Object

Convenient builder for JPA EntityManagerFactory instances. Collects common configuration when constructed and then allows you to create one or more LocalContainerEntityManagerFactoryBean through a fluent builder pattern. The most common options are covered in the builder, but you can always manipulate the product of the builder if you need more control, before returning it from a @Bean definition.
