Spring Data存储库中的默认方法会影响其他方法的缓存吗? [英] Will default methods in Spring Data repositories hit caches on other methods?

问题描述

Spring Data存储库中的默认方法是否会击中同一存储库中其他方法的缓存?

Will default methods in Spring Data repositories hit caches on other methods within the same repository?

例如，将调用此方法:

default Long findIdByCodeRequired(final String code) {
    if (StringUtils.isBlank(code)) {
        throw new DataCheckException(MSG_CODE_REQUIRED, getEntityMessageArgument());
    }
    return findIdByCode(code).orElseThrow(notFound(code));
}

在此方法上缓存吗?

@Cacheable("codeType-findIdByCode")
@Query("select c from #{#entityName} c " //
        + "where c.code = :code")
Optional<Long> findIdByCode(String code);

还是默认方法没有通过缓存才能正常工作所必需的代理?

Or do default methods not go through the proxy necessary for the caching to work?

推荐答案

所以答案是否，存储库中的默认方法不会在其他方法上访问缓存"

So the answer is "no, default methods in a repository will not hit the cache on other methods"

    @Test
    @Transactional
    public void testContactTypeCaching() {
        System.out.println("first call to findIdByCode");
        contactTypeRepo.findIdByCode("MOBILE");
        System.out.println("second call to findIdByCode");
        contactTypeRepo.findIdByCode("MOBILE");
        System.out.println("third call to findIdByCode");
        contactTypeRepo.findIdByCode("MOBILE");
    
        System.out.println("first call to getReferenceByCodeRequired");
        contactTypeRepo.getReferenceByCodeRequired("MOBILE");
        System.out.println("second call to getReferenceByCodeRequired");
        contactTypeRepo.getReferenceByCodeRequired("MOBILE");
        System.out.println("third call to getReferenceByCodeRequired");
        contactTypeRepo.getReferenceByCodeRequired("MOBILE");
    }

输出:

first call to findIdByCode
Hibernate: 
    select
        contacttyp0_.ct_id as col_0_0_ 
    from
        contact_types contacttyp0_ 
    where
        contacttyp0_.code=?
second call to findIdByCode
third call to findIdByCode

first call to getReferenceByCodeRequired
Hibernate: 
    select
        contacttyp0_.ct_id as col_0_0_ 
    from
        contact_types contacttyp0_ 
    where
        contacttyp0_.code=?
second call to getReferenceByCodeRequired
Hibernate: 
    select
        contacttyp0_.ct_id as col_0_0_ 
    from
        contact_types contacttyp0_ 
    where
        contacttyp0_.code=?
third call to getReferenceByCodeRequired
Hibernate: 
    select
        contacttyp0_.ct_id as col_0_0_ 
    from
        contact_types contacttyp0_ 
    where
        contacttyp0_.code=?
