jpa 使用@Column来定义字段类型

@Data
@Entity
public class ColumnDemo {
    @Id
    private Long id;
    @Column(name="name",nullable = false)  // 姓名不能为null，但是可以重复
    private String name;
    @Column(name="mobile",unique = true)
    private String mobile; // 手机号不能重复
    @Column(name="address",length = 512)
    private String address; // 地址 长度512
    private Date datetime;
    @Column(name = "date", columnDefinition = "date")
    private Date date; // 年月日
    @Column(name = "time", columnDefinition = "time")
    private Date time; // 时分秒
    @Column(name = "salary", precision = 5,scale = 3)
//    @Column(name = "salary", columnDefinition = "decimal(10,2)")
    private BigDecimal salary;
    @Column(name = "remark",columnDefinition="text")
    private String remark;
 @Column(name="del_flag",columnDefinition = "varchar(255) comment '删除标志 0:未删除 1:已删除 ")
 private String delFlag;
}

@Lob
@Column(columnDefinition="TEXT")
public String getImgUrls() {
return imgUrls;
}
public void setImgUrls(String imgUrls) {
this.imgUrls = imgUrls;
}
