Spring boot + Spring Data JPA + Hibernate缓存问题_course

如题，项目框架为Spring boot + Spring Data JPA + Hibernate，hibernate中有Query.list()和query.iterator()方法，其中query.iterator()方法去查询时会用到缓存，返回的参数类型是Iterator,如果使用Spring Data JPA+hibernate如何实现查询一个list使用到缓存呢，JPA中的PagingAndSortingRepository接口中的findAll()方法返回的Iterator类型好像和query.iterator()的效果不一样，哪个哥们可以解答下，万分感激！

spring data jpa hibernate批量插入_course

原生的sql，在mysql中可以insert into table(column1,column2) values (), (),()这样批量插入很多数据，jpa中我看好像没有可以批量插入的。请问各位有吗？ 看好多帖说EntityManager.persist()，然后多少条flush(), clear()。我看这种方式hibernate也是一条一条insert执行的，效率并不高。

spring+hibernate配置多数据源动态切换，java实体如何和各个数据库实例映射？_course

我的一个javaweb项目，需要用到多个数据源，都是oracle实例，我用spring配置了数据源的动态切换。使用AOP在service层做拦截，然后用注解DataSource来标示所要选择的数据源。现在我有一个问题，就是我用数据库操作时，hibernate是面向对象的，我该如何将不同的java实体映射到不同的数据源上（不同数据库表结构不同）。比如一个product包中的java实体映射到数据库1，cart包中的实体映射到数据库2。如何做到呢？
