@Column和@Enumerated(EnumType.xxx)的使用

该方式是针对枚举字段的映射,相当于是代码中的数据字典,在存储的时候是对应的序列,查询出数据时替换为具体的数据

@Entity
@Table(name = "employee", schema = "public")
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Employee {

    @Id
    @GeneratedValue
    @Column(name = "id")
    private Long id;

    @Column(name = "name")
    private String name;

    @Column(name = "sex")
    @Enumerated(EnumType.ORDINAL)//性别字段持久化为0,1
    private Sex sex;

    @Column(name = "type")
    @Enumerated(EnumType.STRING)//枚举字符串
    private Type type;
}

 

 

下面是sex对象的代码

public enum Sex {

    MAIL("男"),
    FMAIL("女");

    private String value;

    private Sex(String value) {
        this.value = value;
    }
}
