我有一个复合ID表，在我的数据库中有一个附加字段，以及使用EmbeddedId java持久性注释配置的相应实体模型。在我的应用程序中执行编辑时，一切正常。但是，当尝试使用Hibernate Envers检索审计数据时，代码失败，给我以下堆栈跟踪：

那里有两个主要问题。首先，Contract_Id不是字段。我将JoinColumn配置为＆＃34; FK_CONTRACT＆＃34;的正确名称。其次，我不明白为什么它试图使用java类名作为审计表，而不是使用@Table注释中设置的名称，即＆＃34; CONTRACT_DESIGNS＆＃34;。我的课程如下：
@Entity
@DynamicInsert
@DynamicUpdate
@SelectBeforeUpdate
@Table(name="CONTRACTS")
@Audited
public class Contract implements Serializable {
private static final long serialVersionUID = 1L;
private List<DesignContract> designs;
@OneToMany(mappedBy = "pk.contract", fetch = FetchType.EAGER, cascade = {CascadeType.ALL}, orphanRemoval=true)
@Fetch(value = FetchMode.SUBSELECT)
public List<DesignContract> getDesigns() {
return designs;
}
public void setDesigns(List<DesignContract> designs) {
this.designs= designs;
}
}
@Entity
@AssociationOverrides({
@AssociationOverride(name = "pk.contract",
joinColumns = @JoinColumn(name = "FK_CONTRACT")),
@AssociationOverride(name = "pk.design",
joinColumns = @JoinColumn(name = "FK_DESIGN")) })
@Table(name="CONTRACT_DESIGNS")
@Audited
public class DesignContract implements Serializable {
private static final long serialVersionUID = 1L;
public DesignContract () {
}
public DesignContract (Contract contract, Design design) {
pk.setContract(contract);
pk.setDesign(design);
}
private DesignContractId pk = new DesignContractId();
@EmbeddedId
public DesignContractId getPk() {
return pk;
}
public void setPk(DesignContractId pk) {
this.pk = pk;
}
@Transient
public Contract getContract() {
return getPk().getContract();
}
public void setContract(Contract contract) {
getPk().setContract(contract);
}
@Transient
public Design getDesign() {
return getPk().getDesign();
}
public void setDesign(Design design) {
getPk().setDesign(design);
}
private Double goal;
@Column(name = "GOAL", nullable = true, insertable = true, updatable = true, precision = 5, scale = 2)
@Basic
public Double getGoal() {
return this.goal;
}
public void setGoal(Double goal) {
this.goal = goal;
}
}
@Embeddable
public class DesignContractId implements Serializable {
private static final long serialVersionUID = 1L;
private Contract contract;
private Design design;
@ManyToOne
public Contract getContract() {
return contract;
}
public void setContract(Contract contract) {
this.contract = contract;
}
@ManyToOne
public Design getDesign() {
return design;
}
public void setDesign(Design design) {
this.design = design;
}
}
为所有三个模型实现了toString（），hashCode（）和equals（）方法，为简洁起见，我省略了它们。
我检索审计信息的测试代码是非常基本的，因为我主要只是做一些事情正在发挥作用的概念证明，并且可以初始化附加到我的主契约实体的延迟初始化记录。当我调用DesignContract列表的size（）方法时会发生错误，根据我发现的其他帖子强制Hibernate Enver的ListProxy的使用方法。
AuditReader reader = AuditReaderFactory.get(sessionFactory.openSession());
List<Number> revisionsContract = reader.getRevisions(Contract.class, contractId);
for (Number revisionNum : revisionsContract) {
System.out.println(" revisionNum = " + revisionNum);
Contract contract = reader.find(Contract.class, contractId, revisionNum);
System.out.println(contract.getDesigns().size());
System.out.println(contract.getDesigns());
System.out.println(contract);
}
出于调试目的，我将show_sql设置为true，并且在调用size（）时Hibernate正在尝试的查询没有意义：
select e__ from com.mycompany.model.DesignContract_AUD e__ where e__.contract_id = :contract_id and e__.originalId.REVISION_NUMBER.id = (select max(e2__.originalId.REVISION_NUMBER.id) from com.mycompany.model.DesignContract_AUD e2__ where e2__.originalId.REVISION_NUMBER.id <= :revision and e__.originalId.design = e2__.originalId.design and e__.originalId.contract = e2__.originalId.contract) and REVISION_TYPE != :delrevisiontype
同样，没有contract_id字段，因此我不知道在DesignContract和DesignContractId的模型中给出我的注释会得到什么，并且使用com.mycompany.model.DesignContract_AUD是我根本无法理解的东西。我甚至添加了@AuditTable注释，将其指向CONTRACT_DESIGNS_AUD表，但这并没有改变任何东西。在我的应用程序中执行正常操作（如编辑和保存合同）时，审计信息会正确添加到CONTRACT_DESIGNS_AUD表中，我可以通过直接sql直接查询信息。我不知道为什么会在AuditReader中发生这种情况。我的应用程序中有多个复合ID实体，它们都以相同的方式配置，它们都遇到相同的错误，带有未知的contract_id参数，以及查询中用于审计表的java类名。我确实尝试将我的模型配置为使用@IdClass注释而不是@EmbeddedId，但这只能帮助解析查询中的表名 - 它仍然试图根据contract_id进行过滤，当然，它无法解析。< / p>
我正在使用Hibernate 5.2.10.FINAL，我在阅读了复合ID实体后无法使用早期版本的Hibernate Envers时升级到了https://hibernate.atlassian.net/browse/HHH-7625
对于我做错的任何帮助都将不胜感激。
