这个是主键自增长策略问题。

@GeneratedValue:主键的产生策略，通过strategy属性指定。 

@GeneratedValue(strategy = GenerationType.IDENTITY)

报错：

MySQL连接数据库报时区错误：java.sql.SQLException: The server time zone value

java.sql.SQLException: The server time zone value '�й���׼ʱ��' is

unrecognized or represents more than one time zone. You must configure

either the server or JDBC driver (via the serverTimezone configuration

property) to use a more specifc time zone value if you want to utilize

time zone support.

解决：

为URL添加参数serverTimezone=UTC即可
