EntityManagerFactoryBuilder介绍

[英]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.
[中]方便的JPA EntityManagerFactory实例生成器。构建时收集公共配置，然后允许您通过fluent builder模式创建一个或多个LocalContainerEntityManagerFactoryBean。构建器中包含了最常见的选项，但是如果需要更多的控制，在从@Bean定义返回产品之前，您始终可以操作构建器的产品。
