如何设置@OneToMany 自动生成表的模式？

Question

I want to put all of the following autogenerated tables into a specific schema.

@Entity
@Table(name = "master_table", schema = "test")
public class MasterTable {
    @OneToMany
    private List<VideoEntity> videos;

    @Entity
    @Table(name = "video_entity", schema = "test")
    public static class VideoEntity {

    }
}

Result: there are the two entity tables in test schema, but also one in the public schema called master_table_videos for the list mapping.

Question: how can I tell hibernate to also put the list-mapping table in the same schema than the others?

Answer 1

I think you should use the @JoinTable annotation, at least that allows to set the schema name in standard JPA. Check the JavaDoc for Java EE 7 or Java EE 6 .

So it would be something like @JoinTable(name = "master_to_videos", schema = "test" ) , and you could also specify the name of the join column if required.

Answer 2

Hibernate将在定义实体的任何persistence.xml中创建表。因此，如果MasterTable和VideoEntity都在persistence.xml中，它将在配置的数据模式中创建这两个表。

Answer 3

I agree with Hein Blöd i tested the @joinTable annotation after any other annotation like @ManyToOne @OneToMany... as for your example it becomes like this

@OneToMany
@JoinTable(schema = "testSchema" )
private List<VideoEntity> videos;

testSchema is interpreted by Hibernate as test-schema

i know this is for an old question i'm writing this so that any one right now can find the correct answer i search the inte.net and this is the first question i found.
