MySQL创建自动更新列

table `account` ( `id` int primary key auto_increment, `title` varchar(32) not null comment ‘标题‘, `price` decimal(6,2) default 0.01 comment ‘价格‘, `username` varchar(16) not null comment ‘账号‘, `password` varchar(16) not null comment ‘密码‘, `create_time` timestamp default current_timestamp comment ‘创建时间‘, `update_time` timestamp default current_timestamp on update current_timestamp comment ‘修改时间‘ ) comment ‘账号表‘;

然后修改对应的实体类，添加@DynamicInsert和@DynamicUpdate注解

@Data
@Entity
@DynamicInsert
@DynamicUpdate
public class Account {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    private String title;
    private BigDecimal price;
    private String username;
    private String password;
    private Date createTime;
    private Date updateTime;
}
