使用 haschanged 查询审计 table 时出错

Question

我的模板实体具有：

@ManyToOne
    @JsonView(JsonDefinitionMapper.SecondLevel.class)   
    @Audited
    private TemplateType templateType;

实例。

当我要使用如下实体属性循环查询所有更改时（属性由实体的元数据获取）：

for(String property:PropertiesList){
newValue = auditReader.createQuery()
                                            .forRevisionsOfEntity(Template.class, false, true)
                                            .addProjection(AuditEntity.property(property))
                                            .add(AuditEntity.property(property).hasChanged())
                                            .add(AuditEntity.id().eq(templateId))
                                            .add(AuditEntity.revisionNumber().eq(revisionNumber)).getSingleResult();
}

生成的 Template_AUD table 有 template_type_mod、template_type_id 列（自动生成）

我在运行以上查询时收到此错误：

org.hibernate.QueryException: could not resolve property: templateType of: com.templates.domain.Template_AUD [select e__.templateType from com.templates.domain.Template_AUD e__, com.template.domain.AuditedRevisionEntity r where e__.templateType_MOD = :_p0 and e__.originalId.id = :_p1 and e__.originalId.REV.id = :_p2 and e__.originalId.REV.id = r.id]

我正在使用 postgres 数据库

Answer 1

我最初的想法是利用 Envers 5.2 中添加的新关系遍历 API，通过它您可以编写如下查询：

final List results = auditReader.createQuery()
  .forEntitiesModifiedAtRevision( Template.class, revNo )
  .traverseRelation( "templateType", JoinType.INNER )
    .addProjection( AuditEntity.selectEntity( false ) )
    .up()
  .add( AuditEntity.property( "templateType" ).hasChanged() )
  .getResultList();

这里的想法是，我们基本上会请求在结果列表中返回 TemplateType，但前提是它被认为在根实体 Template 上被修改；但是，此查询引入了我认为是错误的内容：

org.hibernate.QueryException: Named parameter [revision] not set

这是因为添加到根查询的子查询指定了一个命名参数revision；但是，查询逻辑从不绑定修订值；导致这个问题。

我已提交问题 HHH-11981 来解决这个问题。

所以现在，我唯一的建议是，如果您的实体 class 具有超出基本类型属性的任何内容，您可能需要求助于在代码中使用反射来实际从返回的豆子

final List results = auditReader.createQuery()
  .forEntitiesModifiedAtRevision( Template.class, revNo )
  .add( AuditEntity.property( propertyName ).hasChanged() )
  .getResultList();

对于列表中的条目，您需要使用反射为 propertyName 标识的适当属性调用适当的 getter。它不太理想，但至少可以避免您面临的查询问题。

使用 haschanged 查询审计 table 时出错
