為什么代碼里沒有報錯，但是事物操作就是不成功呢？求指教，又是版本問題么？我是1.5.3

IDEA控制臺報錯如下：

java.sql.SQLException: Field 'id' doesn't have a default value

postman返回如下：

{

? ? "timestamp": 1526805315654,

? ? "status": 500,

? ? "error": "Internal Server Error",

? ? "exception": "org.springframework.orm.jpa.JpaSystemException",

? ? "message": "could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement",

? ? "path": "/girls/two"

}
