建议：使用方法二
记录意义：在数据库设置时间类型时，有的使用timestamp ，有的使用datetime，个人推荐使用datetime
@Entity
@Table(name = "m_test")
public class TestTable implements Serializable {
private static final long serialVersionUID = 1L;
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", columnDefinition = "BIGINT")
private Long id;
@Column(name = "user_name", columnDefinition = "varchar(50) NOT NULL COMMENT '用户名称'")
private String userName;
@Column(name = "address", columnDefinition = "varchar(50) NOT NULL COMMENT '用户地址'")
private String address;
@Column(name = "sex", columnDefinition = "tinyint NOT NULL'")
private Integer sex = 0;
@JsonFormat
@Column(name = "cdate", columnDefinition = "DATETIME DEFAULT CURRENT_TIMESTAMP ")
private LocalDateTime cdate = LocalDateTime.now();
@JsonFormat
@Column(name = "mdate", columnDefinition = "DATETIME DEFAULT CURRENT_TIMESTAMP ")
private LocalDateTime mdate = LocalDateTime.now();
