Hibernate删除事务提交时的集合元素

我找不到为什么hibernate会在事务提交后尝试删除集合元素。我甚至没有要求它这样做。Hibernate删除事务提交时的集合元素

任何想法？

技术细节张贴如下。

休眠方言：

org.hibernate.dialect.SQLServerDialect

实体类：

@Entity 
    @Table(name = "View_m_activity", schema = "model") 
    public class SourceActivity { 
     private Set<SourceActivityAttrOut> outputAttributes; 

     private Long ID; 

     @Id 
     public Long getID() { 
      return ID; 
     } 

     public void setID(Long ID) { 
      this.ID = ID; 
     } 

     @ElementCollection(fetch = FetchType.EAGER) 
     @CollectionTable(name = "View_m_activity_attr_out", schema = "model", joinColumns = @JoinColumn(name = "activity_id")) 
     public Set<SourceActivityAttrOut> getOutputAttributes() { 
      return outputAttributes; 
     } 

     public void setOutputAttributes(Set<SourceActivityAttrOut> outputAttributes) { 
      this.outputAttributes = outputAttributes; 
     } 
    }

集合元素实体类：

@Embeddable 
    public class SourceActivityAttrOut { 
     private String code; 

     public String getCode() { 
      return code; 
     } 

     public void setCode(String code) { 
      this.code = code; 
     } 
    }

执行代码：

@Transactional 
    public void readSource(SourcePool sourcePool) { 
     sessionFactory.getCurrentSession().createQuery("from SourceActivity", SourceActivity.class).list(); 
    }

登录信息：

Hibernate: 
    select 
     sourceacti0_.ID as ID1_0_ 
    from 
     model.View_m_activity sourceacti0_ 

Hibernate: 
    select 
     outputattr0_.activity_id as activity1_1_0_, 
     outputattr0_.code as code2_1_0_ 
    from 
     model.View_m_activity_attr_out outputattr0_ 
    where 
     outputattr0_.activity_id=? 

Hibernate: 
    select 
     outputattr0_.activity_id as activity1_1_0_, 
     outputattr0_.code as code2_1_0_ 
    from 
     model.View_m_activity_attr_out outputattr0_ 
    where 
     outputattr0_.activity_id=? 

Hibernate: 
    select 
     outputattr0_.activity_id as activity1_1_0_, 
     outputattr0_.code as code2_1_0_ 
    from 
     model.View_m_activity_attr_out outputattr0_ 
    where 
     outputattr0_.activity_id=? 

Hibernate: 
    select 
     outputattr0_.activity_id as activity1_1_0_, 
     outputattr0_.code as code2_1_0_ 
    from 
     model.View_m_activity_attr_out outputattr0_ 
    where 
     outputattr0_.activity_id=? 

Hibernate: 
    delete 
    from 
     model.View_m_activity_attr_out 
    where 
     activity_id=?

在日志中我发现： – PMV

'[TRACE] LoadContexts.locateLoadingCollectionEntry：249 - 试图找到加载收集条目[CollectionKey [ru.avkcom.blackbox.modelimporter.db.domain.SourceActivity.outputAttributes＃10000001]] in任何结果集上下文' – PMV

'[TRACE] LoadContexts.locateLoadingCollectionEntry：255 - 集合[CollectionKey [ru.avkcom.blackbox.modelimporter.db.domain.SourceActivity.outputAttributes＃10000001]]位于加载上下文中' – PMV

的问题的原因描述here

不久，解决我不得不重写了hashCode和SourceActivityAttrOut的等于问题。
