Hibernate Envers:查询修订版本时出现问题
我使用 Hibernate Envers 进行审计。我的实体看起来像这样:
@Entity
@Audited
public class Child
{
@GeneratedValue
@Id
@Column
private Long id;
@Column
private String test;
// getters & setters
}
现在我想查询这样的修订:
query = reader.createQuery().forRevisionsOfEntity(Child.class, false, true);
query.add(AuditEntity.property("test").eq("child1"));
Long id = ...;
query = reader.createQuery().forRevisionsOfEntity(Child.class, false, true);
query.add(AuditEntity.property("id").eq(id));
第一个查询有效,执行第二个查询会抛出以下异常:
java.lang.ClassCastException: java.lang.Long cannot be cast to java.util.Map

我不知道为什么这会导致 ClassCastException。知道吗,我缺少什么?
I use Hibernate Envers for auditing. My entity looks like this:
@Entity
@Audited
public class Child
{
@GeneratedValue
@Id
@Column
private Long id;
@Column
private String test;
// getters & setters
}
Now I would like to query revisions like this:
query = reader.createQuery().forRevisionsOfEntity(Child.class, false, true);
query.add(AuditEntity.property("test").eq("child1"));
Long id = ...;
query = reader.createQuery().forRevisionsOfEntity(Child.class, false, true);
query.add(AuditEntity.property("id").eq(id));
The first query works, executing the second throws the following exception:
java.lang.ClassCastException: java.lang.Long cannot be cast to java.util.Map

I have no clue why this leads to a ClassCastException. Any idea, what I'm missing?

比较两个审核实体的 ID 时,请使用
AuditEntity.id()
而不是AuditEntity.property()
。When comparing the ids of two audited entities, use
AuditEntity.id()
instead ofAuditEntity.property()
._aud 表条目的 id 由实体的 id、REV 和 REVTYPE 组成,因此它是 3 个值的映射。最好的选择是使用 AuditEntity.id(),但 AuditEntity.property("id.id") 也可以
the id of an entry of a _aud table is made of the id of the entity, the REV, and the REVTYPE, so, its a map of 3 values. the best choice is using AuditEntity.id(), but AuditEntity.property("id.id") would also make it
