Java Hibernate@id复合

我正在为数据库建模。
有三个

TRIPLE

，其中包含三个

概念。因此类
TRIPLE
的主键是三个
uri
。（一个概念可以是不同的
TRIPLE
）。

另外，
TRIPLE
与另一个类，
ANNOTATION
相关，这里有一个问题，如何识别
TRIPLE\u id
？？但首先，如果构建这个Id组合是正确的。
要建立模型，请执行以下操作：

Concept.java

@Entity
@Table(name = "concept")
public class Concept implements java.io.Serializable {

    private static final long serialVersionUID = 1L;
    private String id;
    private List<TripleDBModel> triples;  
@ManyToMany(
            cascade={CascadeType.ALL},  
            fetch=FetchType.LAZY, 
            mappedBy = "concepts"  
    )   
    public List<TripleDBModel> getTriples() {
        return triples;
    }

    public void setTriples(List<TripleDBModel> triples) {
        this.triples = triples;
    }

@Embeddable
public class ConceptPk implements java.io.Serializable {

    private static final long serialVersionUID = 1L;
    private String uri;

    public ConceptPk(String uri, String label){
        this.uri = uri;
    }

    public ConceptPk(){
        super();
    }   

    @Id
    @Column(name = "uri", length = 100, unique = true, nullable = false)
    public String getUri() {
        return uri;
    }
    public void setUri(String uri) {
        this.uri = uri;
    }
}

@Entity
@IdClass(ConceptPk.class)
@Table(name = "triple")
public class TripleDBModel {

    protected List<Annotation> annotations;
    protected String conceptUriSubject;
    protected String conceptUriObject;
    protected String conceptUriPredicate;



    @ManyToMany(
            cascade={CascadeType.ALL},  
            fetch=FetchType.LAZY
    )   
    @JoinTable(name = "triple_has_concept", 
            joinColumns=@JoinColumn(name="uri"),
            inverseJoinColumns=@JoinColumn(name="triple_id")) //What shoul I write here???
    public List<Annotation> getAnnotations() {
        return annotations;
    }
    public void setAnnotations(List<Annotation> annotations) {
        this.annotations = annotations;
    }
    @Id public String getConceptUriSubject() {
        return conceptUriSubject;
    }
    public void setConceptUriSubject(String conceptUriSubject) {
        this.conceptUriSubject = conceptUriSubject;
    }
    @Id public String getConceptUriObject() {
        return conceptUriObject;
    }
    public void setConceptUriObject(String conceptUriObject) {
        this.conceptUriObject = conceptUriObject;
    }
    @Id public String getConceptUriPredicate() {
        return conceptUriPredicate;
    }
    public void setConceptUriPredicate(String conceptUriPredicate) {
        this.conceptUriPredicate = conceptUriPredicate;
    }
}  

Triple.java

@Entity

    private static final long serialVersionUID = 1L;

    )   
    public List<TripleDBModel> getTriples() {
        return triples;
    }

    public void setTriples(List<TripleDBModel> triples) {
        this.triples = triples;
    }

    }

    public ConceptPk(){
        super();
    }   

    @Id

    public String getUri() {
        return uri;
    }
    public void setUri(String uri) {
        this.uri = uri;
    }
}

@Entity

提前谢谢
 您可以使用如下Id类：

class TripleId implements Serializable {
  @Column(...)
  private String conceptUriSubject;

  @Column(...)
  private String conceptUriObject;
}

并以三种形式使用：

@Entity
@Table(name = "triple")
public class TripleDBModel {

  @EmbeddedId
  private TripleId id;
  ...
}

还请注意，您可以提供多个联接列：
inverseJoinColumns={@JoinColumn（name=“subarchitecture”），@JoinColumn（name=“objectUri”），…}
