Mysql数据库 hibernate保存数据时,Mysql主键需设定自增,否则报错

问题的原因很简单,可能有的时候一下想不起来。MARK下。
 
报错信息如下:
org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: could not insert: [com.wondertek.meeting.model.spokesman.Spokesman]; uncategorized SQLException for SQL [insert into Spokesman (mobile, gender, create_time, creator) values (?, ?, ?, ?)]; SQL state [HY000]; error code [1364]; Field 'id' doesn't have a default value; nested exception is java.sql.SQLException:
 
Field 'id' doesn't have a default value
