好的,这个问题的答案可能是在春季文档here或here中,但是我找不到它。 我正在尝试实施软删除。 到目前为止,一切正常。除非我通过关联获得记录。
示例:
http://localhost:8080/api/accounts
返回正确的帐户列表(不显示is_deleted = true的任何帐户)
和
http://localhost:8080/api/addresses
返回正确的地址列表(不显示is_deleted = true
处的任何地址)
但是当我按下http://localhost:8080/api/accounts/3c84cdb1-6a01-4364-a60b-305afc521440/addresses
时,我会得到所有地址的列表。即使是is_deleted = true
这是我自定义的baseRepository:
@NoRepositoryBean
public interface BaseRepository<T extends BaseEntity, ID> extends JpaRepository<T,ID>{
void obliterateEntity(T entity);
@Override
@Transactional(readOnly = true)
@Query("select e from #{#entityName} e where e.isDeleted = false")
Page<T> findAll(Pageable pageable);
@Override
@Transactional(readOnly = true)
@RestResource(exported=false)
@Query("select e from #{#entityName} e where e.isDeleted = false")
List<T> findAll(Sort var1);
@Override
@Transactional(readOnly = true)
@RestResource(exported=false)
@Query("select e from #{#entityName} e where e.isDeleted = false")
List<T> findAllById(Iterable<ID> var1);
@Override
@Transactional(readOnly = true)
@RestResource(exported=false)
@Query("select e from #{#entityName} e where e.isDeleted = false")
List<T> findAll();
@Override
@Transactional(readOnly = true)
@RestResource(exported=false)
@Query("select e from #{#entityName} e where e.isDeleted = false and e.id = ?1")
Optional<T> findById(ID var1);
@Query("update #{#entityName} e set e.isDeleted=true where e.id = ?1")
@Transactional
@Modifying
void delete(UUID id);
@Override
@Transactional
default void delete(T entity) {
delete(entity.getId());
}
}
问题: 通过关联链接获取删除的记录时,我需要重写哪些方法?
p.s。我也尝试这样做,而不是覆盖功能:
@SQLDelete(sql =
"UPDATE address " +
"SET is_deleted = true " +
"WHERE id = ?")
@Loader(namedQuery = "findAddressById")
@NamedQuery(name= "findAddressById", query =
"SELECT add " +
"FROM Address add " +
"WHERE " +
"add.id = ?1 AND " +
"add.isDeleted = false")
@Where(clause = "is_deleted = false")
public class Address extends BaseEntity {
但是,这需要在每个实体中执行相同的操作。它还具有其他实现问题。
我想我在进行软删除时遇到了麻烦。因此,我们将不胜感激。
答案 0 :(得分:1)
您将需要在关联上添加@Where
。
public class Account extends BaseEntity {
@OneToMany
@Where(clause = "is_deleted = false")
private Set<Address> addresses;
}
您添加到@Where
的{{1}}仅对直接加载地址有影响(鉴于您已定义要加载数据的查询,这似乎是多余的)。
