如何在Spring Data JPA CRUDRepository中添加缓存功能 [英] How to add cache feature in Spring Data JPA CRUDRepository

问题描述

我想在findOne方法中添加Cacheable注释，并在删除或发生方法发生时驱逐缓存。

I want to add "Cacheable" annotation in findOne method, and evict the cache when delete or happen methods happened.

我该怎么做？

推荐答案

virsir，如果您使用Spring Data JPA（仅使用接口），还有一种方法。这里我做了什么，为类似的结构化实体创建了dao：

virsir, there is one more way if you use Spring Data JPA (using just interfaces). Here what I have done, genereic dao for similar structured entities:

public interface CachingDao<T, ID extends Serializable> extends JpaRepository<T, ID>, JpaSpecificationExecutor<T> {

@Cacheable(value = "myCache")
T findOne(ID id);

@Cacheable(value = "myCache")
List<T> findAll();

@Cacheable(value = "myCache")
Page<T> findAll(Pageable pageable);

....

@CacheEvict(value = "myCache", allEntries = true)
<S extends T> S save(S entity);

....

@CacheEvict(value = "myCache", allEntries = true)
void delete(ID id);
}
