以前有人处理过这个错误吗？（org.hibernate.action.internal.EntityActionVetoException:EntityInsertAction被否决）

我想在将excel文件数据推入数据库之前将其保存到会话中，因此我尝试将其保存到会话中，但它始终显示以下错误org.hibernate.action.internal.EntityActionVetoException:EntityInsertAction被否决

values.each {

                println("")
                println(it)
                println("abctesting")
//                println("values -> " + it)

                def newObjectInstance = objectInstance.propertyMapping(it)
                println("abctesting")

                newObjectInstance.each{ obj ->
                    println(obj.colorName)
                    println(obj.price)
                    println(obj.totalVolume)
                }

                if (newObjectInstance != null) {
                    //why cannot save into session??????
                    session.save(newObjectInstance)
                }
                else {
                    System.err.println("Data Import: I am NULL. Processing object -> ${newObjectInstance}")
                }
                println("abctesting")

                if (counter % 1000 == 0) {
                    println("Counter -> " + counter)
                    println("Flush and Clear Session")
                    //clear session and save records after every 100 records
                    session.flush();
                    session.clear();
                }

                if (counter % 10000 == 0) {
                    println("Process -> " + counter)
                }

                counter++
            }

            //Commit and close Session
            tx.commit();
            session.close();
            LocalTime endTime = LocalTime.now()
            println("Start Time      -> ${startTime}")
            println("End Time        -> ${endTime}")
            println("Duration (sec)  -> ${Duration.between(startTime, endTime).toMillis() / 1000}")
            println("Done Processing -> ${className}")

我在session.save（newObjectInstance）上找到了导致此错误的行。在注释掉这一行之后，这段代码就开始工作了。但这不是方法，因为它没有保存到会话和数据库中
