Spring Data存储库中的默认方法会在其他方法上命中缓存吗?

Question

Spring Data存储库中的默认方法是否会影响同一存储库中其他方法的缓存?

例如，调用这个方法:

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

在此方法上命中缓存?

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

或者默认方法不通过缓存工作所需的代理吗?

Answer 1

所以答案是"不，存储库中的默认方法不会在其他方法上缓存">

@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=?
