spring - 将 PersistenceExceptionTranslationPostProcessor 与 Spring 的 JdbcTemplate 一起使用是否有意义？

Question

标题不言自明。

PersistenceExceptionTranslationPostProcessor 是仅用于 JPA 实现还是将其与 Spring 的 JdbcTemplate 一起使用？

如果需要两个数据源，每个数据源都有自己的 JPA 实体管理器和事务管理器，我是否仍然只需要为整个应用程序指定一个 PersistenceExceptionTranslationPostProcessor ？

The @Repository annotation can have a special role when it comes to converting exceptions to Spring-based unchecked exceptions. Recall that the JdbcTemplate handled this task for us. When we work with Hibernate, we’re not going to work with a Spring template that handles this conversion of Hibernate-based exceptions to Spring-based exceptions. As a result, in order to handle this conversion automatically, Hibernate DAOs annotated with @Repository will have their Hibernate exceptions rethrown as Spring exceptions using a PersistenceExceptionTranslationPostProcessor.

上一段明确指出:
回想一下，JdbcTemplate 为我们处理了这个任务

因此，要回答我自己的问题，不需要将 PersistenceExceptionTranslationPostProcessor 与 jdbcTemplate 一起使用
