Spring 数据 Jpa：保存方法仅返回 select 但不执行插入

Question

I am trying to save/update an entity by using spring data JPA. I have 2 entity which are almost similar. Both entities contain composite keys. Save method is working fine on one entity. Save method not working on another entity. Insertion/update is not happening upon calling save method. It is just returning select statement.

Update / save works on ContentCoreNluRepository

But only select statements are returning from the repository RelationShipTypeRepository

I am not sure where I am going wrong.

My code below.

@SpringBootApplication
public class CdsRmsOutputDbApplication implements CommandLineRunner {

    @Autowired
    RelationShipTypeRepository relationShipTypeRepository;

    @Autowired
    ContentCoreNluRepository contentCoreNluRepository;

    public static void main(String[] args) {
        SpringApplication.run(CdsRmsOutputDbApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {

        RelationShipType relationShipType = new RelationShipType("TEJA_3059", "alias", "UUCID", "TEJA_3059", "N");

        relationShipTypeRepository.saveAndFlush(relationShipType);

        ContentCoreNlu contentCoreNlu = new ContentCoreNlu(4569l, "Topiccsq", "Analyticscqs", "Analytics", "N",
                BigDecimal.valueOf(0.9999));
        ContentCoreNlu contentCoreNlu1 = new ContentCoreNlu(4569l, "Topiccs", "Analyticscs", "Analytics", "N",
                BigDecimal.valueOf(0.9999));
        ContentCoreNlu contentCoreNlu2 = new ContentCoreNlu(4569l, "Topic", "Analytics", "Analytics", "N",
                BigDecimal.valueOf(0.9999));

        List<ContentCoreNlu> contentList = new ArrayList<>();

        contentList.add(contentCoreNlu);
        contentList.add(contentCoreNlu1);
        contentList.add(contentCoreNlu2);

        contentCoreNluRepository.saveAndFlush(contentCoreNlu);

    }

}

Here is my Entity 1

@Entity
@Table(name = "content_core_relshp")
@IdClass(RelationShipTypeId.class)
@EntityListeners(AuditingEntityListener.class)
public class RelationShipType {

    @Id

    private java.util.Date createTs;

    @Temporal(TemporalType.TIMESTAMP)
    @LastModifiedDate
    private java.util.Date updateTs;

    /**

    public RelationShipType() {
        super();

    }

            String inactFlag) {
        super();
        this.universalContentId = universalContentId;
        this.relationType = relationType;
        this.contentTypeId = contentTypeId;
        this.contentId = contentId;
        this.inactFlag = inactFlag;
    }

    public String getUniversalContentId() {
        return universalContentId;
    }

    public String getRelationType() {
        return relationType;
    }

    public String getContentTypeId() {
        return contentTypeId;
    }

    public String getContentId() {
        return contentId;
    }

    public String getInactFlag() {
        return inactFlag;
    }

    public java.util.Date getCreateTs() {
        return createTs;
    }

    public java.util.Date getUpdateTs() {
        return updateTs;
    }

    @Override
    public String toString() {
        return "RelationShipType [universalContentId=" + universalContentId + ", relationType=" + relationType

                + ", createTs=" + createTs + ", updateTs=" + updateTs + "]";
    }

}

I have composite key on my variables.

Answer 1

Spring data is performing hibernate merge when entity is assumed as "not new" (see: https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.entity-persistence.saving-entites.strategies ). Merge doesn't execute update if entity was not changed. It seems that you already have relationShipType entity with the same identifier in DB and it is equal to the entity you're try to update.
