我有以下映射:
public enum JobType {
CLEANER,
CRAWLER, ...
}
public class JobId implements Serializable {
private int accId;
private String env;
private JobType jobType;
}
@SuppressWarnings("serial")
@Entity
@Table(name = "jobs")
public class JobExecution {
@EmbeddedId
@AttributeOverrides({
@AttributeOverride(name = "accId", column = @Column(name = "acc_id")),
@AttributeOverride(name = "env", column = @Column(name = "env")),
@AttributeOverride(name = "jobType", column = @Column(name = "agg_type")) })
private JobId jobId;
@Enumerated(EnumType.STRING)
@Column(name = "Job_STATUS")
private JobStatus jobStatus;
//... other staff
}
作业状态枚举列写入正常,其中包含字符串值。
但是jobType写的是序数值(0,1,...),而不是名字(CLEANER,CRAWLER ......)。
我想在数据库中写入JobType枚举名称而不是它的序数()值。
我可以在@EmbeddedId中添加哪个映射来为jobType列提示此属性?
答案 0 :(得分:1)
这样做的方法是直接在字段上使用@Enumerated annotation:
@Enumerated(EnumType.STRING)
如果需要,我猜您可以使用JobId
为@Embeddable
课程添加注释,然后将@Enumerated
注释放在JobType
字段上:
@Embeddable
public class JobId implements Serializable {
private int accId;
private String env;
@Enumerated(EnumType.STRING)
private JobType jobType;
}
