春季数据jpa中的拦截器

Question

我正在使用 spring data jpa，我想拦截保存、删除或更新等休眠操作。

我创建了扩展 EmptyInterceptor 的 MyInterceptor。这个类，让我们说实体保存（删除，编辑）到数据库后的日志消息。花了很多时间，无法添加到spring data jpa

所以我的问题是，我应该在哪里将 MyInterceptor 添加到 spring data jpa 以拦截所有实体。

下面的链接显示了如何在休眠中执行此操作。

（场景）假设管理员在商店中创建一个项目，如果项目成功保存到数据库，我的拦截器会捕获它并执行一些操作。

任何链接，建议？ 提前致谢

我使用的是 Spring boot 1.4.3，postgresql 9.5

如果您正在寻找审计目的： 最好在 spring data jpa docs 中解释：https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.auditing.configuration

如果你想拦截 JpaRepository 操作： 您可以通过定义方面并提供有关 JpaRespository 操作的建议来使用 AOP 编程pointcut="execution(public * org.springframework.data.jpa.repository.JpaRepository+.*(..))"
