Hibernate many-many relation does persist to DB

[Edward F Sinaga]

Halo semua,

saya mau bertanya ttg relasi many-to-many di hibernate.

sy punya relasi sbb, dmn di table SnsTokenMessage memiliki kolom tambahan articleId.

SnsMessage <------- SnsTokenMessage -------> SnsToken

ketika ingin menyimpan SnsTokenMessage, kenapa tidak bisa ya?

konfigurasi yg sy buat ini mengikuti tutorial disini, dan aneh nya tidak bisa. Apa karena versi hiberate / library?

tidak ada exception / error yg terjadi. Berikut snippet code yg saya punya

SnsMessage snsMessage = snsMessageDao.findById(messageId);

for (SNSMasterDTO dto : listDto) {

if(dto.getState()){

String snsName = dto.getName();

String message = snsMessage.getMessageText();

String articleId = "";

String storedToken = dto.getStoredToken();

SnsToken snsToken = snsTokenDao.findByToken(storedToken);

articleId = .... ambil article ID

SnsTokenMessage snsTokenMessage = new SnsTokenMessage();

snsTokenMessage.setSnsToken(snsToken);

snsTokenMessage.setSnsMessage(snsMessage);

snsTokenMessage.setArticleId(articleId);

snsMessage.getSnsTokenMessages().add(snsTokenMessage);

}

}

snsMessageDao.update(snsMessage); //update snsMessage. Tetapi kenapa SnsTokenMessage tidak di save oleh hibernate?

@NamedQueries({

@NamedQuery(name = "findSnsMessageByClient", query = "select snsMessage from SnsMessage snsMessage where snsMessage.content.id = :id")

})

@Entity

@Table(name="SNS_MESSAGE")

public class SnsMessage extends Model {

@OneToMany(mappedBy = "pk.snsMessage", fetch = FetchType.LAZY, cascade = {CascadeType.PERSIST, CascadeType.MERGE})

    @Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.DELETE_ORPHAN})

private Set<SnsTokenMessage> snsTokenMessages = new HashSet<SnsTokenMessage>();

...getter setter

}
