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 auditorProvider() {
        return new AuditorAwareImpl();
    }

    ...

}
