springboot mysql 插入数据报错

Question

应该怎么解决

• 用的是mybatis-plus自带的insert方法，driver中两个属性有值，所有字段，除了主键id都可以为空。driver的id为空，数据库id自增

• serviceImpl中这句报错

int result = driverEntityMapper.insert(driver);

• org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
• Error updating database. Cause: java.lang.IllegalArgumentException: non null key required
• The error may exist in com/xxxx/mapper/DriverEntityMapper.java (best guess)
• The error may involve com.xxx.mapper.DriverEntityMapper.insert
• The error occurred while executing an update
• Cause: java.lang.IllegalArgumentException: non null key required

参数异常，看下数据库和你的插入的实体对象。数据库中有哪些是必填的不能为空的，和你入参实体比较下。
