Spring JPA Data Auditing

阐述如何使用Spring的JpaAuditing来方便的给auditing相关的字段赋值 官方文档 baeldung 示例

注意： 来自官方文档：

If you have multiple implementations registered in the ApplicationContext, you can select the one to be used by explicitly setting the auditorAwareRef attribute of @EnableJpaAuditing.

示例：

@EnableJpaAuditing(auditorAwareRef="auditorProvider")
public class PersistenceConfig {

    ...

    @Bean
    AuditorAware<String> auditorProvider() {
        return new AuditorAwareImpl();
    }

    ...

}
