如何在hibernate中为@ElementCollection设置表名

Question

我在用

public class UserTask extends BaseObject implements Serializable {

    @ElementCollection(targetClass = java.lang.String.class) 
    private List<String> userTaskMessage = new ArrayList<>();

   .
   .
   .
   .

Hibernate生成表,名称是usertask_usertaskmessage.

我如何设置我的名字？例如my_table_example

谢谢您的帮助!

Answer 1

使用注释@CollectionTable(name ="your_table_name")

Answer 2

JPA:

@Entity
@Table(name = "SERVICES")
public class Service {

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

    @ElementCollection(fetch = FetchType.LAZY)
    @CollectionTable(name = "SERVICE_LINKED_CODES", joinColumns = @JoinColumn(name = "SERVICE_ID"))
    @Column(name = "CODE") 
    private List<String> linkedCodes;

}

DB中的架构:

CREATE TABLE SERVICES { ID BIGINT };
CREATE TABLE SERVICE_LINKED_CODES { SERVICE_ID BIGINT, CODE VARCHAR(255) };
