ORA-02291：违反了完整性约束（GOPI.SYS_C007099） - 使用Hibernate找不到父键

Question

我用MySQL实现了hibernate项目，工作正常。但是我的客户想在Oracle 11g中使用它，但是下面的代码却抛出了这个错误。

  

引起：java.sql.SQLIntegrityConstraintViolationException：ORA-02291：违反了完整性约束（GOPI.SYS_C007099） - 未找到父密钥

这是我的以下代码与@oneToMany @ManyToOne关系

我有3个实体

1. 流程
2. Process_analysis
3. Process_Steps




@Entity Process have 
@oneToMany  with
Process_analysis And
@oneToMany 
Process_Steps 

以下是我如何坚持

Process_Steps  proSteps=new Process_Steps ();

        List<Process_analysis> pro_Anlist =new ArrayList<Process_analysis>();
        java.util.Date date=new java.util.Date();

        this.bean.setCancelled_Flg('F');
        this.bean.setUser_Id("xyz");
        this.bean.setpro_Status("xyz");
        this.bean.setPro_Description("dsfdfdfsdf");
        this.bean.setLast_Updated_Date(new Timestamp(date.getTime()));
        proService.merge(this.bean); //Persisting or merging Process Entity

        for(int i=0;i<3;i++){
        Process_analysis proAn=new Process_analysis();
        proAn.setCase_Protocal_Id("CASE:"+i);
        proAn.setPro(this.bean);
        proAnService.persist(proAn); //Persisting Each process analysis for Process NOTE:Throws Error Here 
        pro_Anlist.add(proAn);
        }

        proSteps.setRemarks("The StackOverflow");

        proSteps.setStart_Time(new Timestamp(date.getTime()));
        proSteps.setEnd_Time(new Timestamp(date.getTime()));
        proSteps.setPro(this.bean);           //Setting Foreign key of Process
        proStepsService.persist(proSteps);

        this.bean.getProAna().addAll(pro_Anlist);
        this.bean.getProSteps().add(proSteps);
        proService.merge(this.bean);`
