如何解决Hibernate中的错误“ getter内发生异常”？

Question

保存数据时向我显示以下错误： 在de.pares.int_plan.entity.DepositDeadlineEntity.negFive null的getter内部发生异常

我们在后端使用了Java和ORM休眠。 我从前端获取数据并保存。通常这是可行的，但不幸的是在这种情况下不可行。而且我不知道我到底在做什么错。

代码

 public PlanlinevaluesEntity changePlanValues(PlanlinevaluesEntity plan, Map requestBody) throws IllegalAccessException {
...
...
...
            for (Object key : requestBody.keySet()) {
                if (!key.equals("depositDeadlineId")) {
                    for (Field field : ddFields) {
                        if (field.getName().equals(key)) {
                            DepositDeadlineEntity ddE = new DepositDeadlineEntity();
                            DepositDeadlineManager ddM = new DepositDeadlineManager();

                            ddE.applyValue(field, requestBody.get(key));
                            ddE.setPlanlinevaluesId(plan.getPlanlinevaluesId());
                            ddM.saveOrUpdate(ddE);

                            if (ddE.getDepositDeadlineId() != null && ddE.getDepositDeadlineId() > 0) {
                                plan.setDepositdeadlineId(ddE.getDepositDeadlineId());
                                new PlanLineValuesManager().saveOrUpdate(plan);
                            }
                        }
                    }
                }
            }
        }
...
...
...

我的实体如下：

@Entity

    }

    @Basic

    @Basic

    @Basic

    }

    @Basic

    }

    @Basic

        return negThree;
    }

    public void setNegThree(double negThree) {
        this.negThree = negThree;
    }

    @Basic

    }

    public void applyValue(Field field, Object value) throws IllegalAccessException {
        field.set(this, ObjectFieldValueConverter.convert(field, value));
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        DepositDeadlineEntity that = (DepositDeadlineEntity) o;
        return depositDeadlineId.equals(that.depositDeadlineId) &&
                posSeven.equals(that.posSeven) &&
                posSix.equals(that.posSix) &&
                posFive.equals(that.posFive) &&
                posFour.equals(that.posFour) &&
                posThree.equals(that.posThree) &&
                posTwo.equals(that.posTwo) &&
                posOne.equals(that.posOne) &&
                zero.equals(that.zero) &&
                negOne.equals(that.negOne) &&
                negTwo.equals(that.negTwo) &&
                negThree.equals(that.negThree) &&
                negFour == that.negFour &&
                negFive == that.negFive &&
                negSix == that.negSix;
    }

    @Override
    public int hashCode() {
        return Objects.hash(depositDeadlineId, posSeven, posSix, posFive, posFour, posThree, posTwo, posOne, zero, negOne, negTwo, negThree, negFour, negFive, negSix);
    }

Nullable = false是sql级别的拦截器。 由于数据来自前端，因此我可以排除使用negFive解决该吸气剂

{
    "posOne": 70,
    "negOne" : 30
}

有人知道这个错误或我在做什么错吗？
