问题描述

我可以将Query Cache和Spring Data JPA一起用于以下自定义查询方法.

I am able to use Query Cache with Spring Data JPA for my custom query methods like below.

public interface CountryRepository extends JpaRepository<Country, String> {
@QueryHints({ @QueryHint(name = "org.hibernate.cacheable", value ="true") })
Country findByCountryName(String countryName);
@QueryHints({ @QueryHint(name = "org.hibernate.cacheable", value ="true") })
Country findByCountryCode(String countryCode); }

但是,如何在现有的父方法(如findAll())上添加@QueryHints?

However, how to add @QueryHints on existing parent methods like findAll()?

谢谢.

推荐答案

findAll(),findOne()等不是查询.这些实体上的所有缓存规范都将在这些方法中生效.

findAll(), findOne() etc. are not Query(s). Any caching specifications on the entity take effect in these methods.

例如,

@Cacheable
@Entity
public class User {

}
