java如何配置Hibernate Envers以避免实体修订查询中的某些集合（联接表）

Question

我使用的是HibernateEnvers 4.2，我只想从实体中的一些集合获取实体的修订版，其中包含详细信息

但我可以看到，对实体中的所有集合启动hibernate查询会导致性能问题

也无法在此特定查询中避免对集合使用@NotAudited注释，因为在其他场景中需要对这些集合进行审核

例如，如果我的审计实体将这两个连接作为集合。 但是我希望查询只获取地址信息而忽略订单信息，这可能吗？我不想用@NotAudited注释订单信息，因为在其他场景中可能需要历史信息

@ManyToOne
@JoinColumn(name="ADDR_ID")
public Address getAddress() { return address; }

@OneToMany
@JoinColumn(name="CUST_ID") 
public Set<Order> getOrders() {return orders;}

Answer 1

与this Hibernate documentation example一样，如果我有一个Customer与Address关联：

@Audited( withModifiedFlag = true )
@Entity(name = "Customer")
public class Customer {

    ...

    @ManyToOne(fetch = FetchType.LAZY)
    private Address address;

}

我使用this query查询修订：

List<Customer> customers = AuditReaderFactory
.get( entityManager )
.createQuery()
.forRevisionsOfEntity( Customer.class, false, true )
.add( AuditEntity.id().eq( 1L ) )
.add( AuditEntity.property( "lastName" ).hasChanged() )
.getResultList();

Envers仅查询Customers，而不是Address：

select
    c.id as id1_3_0_,
    c.REV as REV2_3_0_,
    defaultrev1_.REV as REV1_4_1_,
    c.REVTYPE as REVTYPE3_3_0_,
    c.REVEND as REVEND4_3_0_,
    c.created_on as created_5_3_0_,
    c.createdOn_MOD as createdO6_3_0_,
    c.firstName as firstNam7_3_0_,
    c.firstName_MOD as firstNam8_3_0_,
    c.lastName as lastName9_3_0_,
    c.lastName_MOD as lastNam10_3_0_,
    c.address_id as address11_3_0_,
    c.address_MOD as address12_3_0_,
    defaultrev1_.REVTSTMP as REVTSTMP2_4_1_
from
    Customer_AUD c cross
join
    REVINFO defaultrev1_
where
    c.id = ?
    and c.lastName_MOD = ?
    and c.REV=defaultrev1_.REV
order by
    c.REV asc

  binding parameter [1] as [BIGINT]  - [1]
  binding parameter [2] as [BOOLEAN] - [true]

除非您像这样浏览关联：

AuditQuery innerJoinAuditQuery = AuditReaderFactory
.get( entityManager )
.createQuery()
.forEntitiesAtRevision( Customer.class, 1 )
.traverseRelation( "address", JoinType.INNER );

Hibernate Envers不应将它们包含在SQL修订查询中
