JPA：多对多过滤器查询

Question

我使用另一个中间表ClusterTag在Cluster表和Tag表之间建立了多对多关系。下面，我有双向映射。

对于用户可以指定多个（TagName和TagValue）组合的场景，我需要提出查询（JPA / HIBERNATE）的帮助，并且我只需要检索那些具有与TagName和TagValues关联的所有组合的集群与他们在一起，如WHERE（tagName =？AND tagValue =？）AND（tagName =？AND tagValue =？）........

 @Entity(name = “Cluster”)
    @Table(name = “cluster”)
    public class ClusterDto implements Serializable {
    private static final long serialVersionUID = -3501772243949297059L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", updatable = false, nullable = false)
    private Integer id;

    @Column(name = "uuid", nullable = false, unique = true)
    @Convert(converter = UUIDConverter.class)
    private UUID uuid;

    @Column(name = "mapped_id", nullable = false)
    private String mappedId;

    @Column(name = "create_time", nullable = false, updatable = false)
    @CreationTimestamp
    private Timestamp createTimestamp;

    @Column(name = "last_update", nullable = false)
    @UpdateTimestamp
    private Timestamp updateTimestamp;

    @OneToMany(
        mappedBy = "cluster",
        cascade = CascadeType.ALL,
        orphanRemoval = true
    )
    private List<ClusterTagDto> tags = new ArrayList<>();


    public void addTag(TagDto tag) {
        ClusterTagDto clusterTag = new ClusterTagDto(this, tag);
        tags.add(clusterTag);
        tag.getClusters().add(clusterTag);
    }


    public void removeTag(TagDto tag) {
        for (Iterator<ClusterTagDto> iterator = tags.iterator();
             iterator.hasNext(); ) {
            ClusterTagDto clusterTag = iterator.next();

            if (clusterTag.getCluster().equals(this) &&
                clusterTag.getTag().equals(tag)) {
                iterator.remove();
                clusterTag.getTag().getClusters().remove(clusterTag);
                clusterTag.setCluster(null);
                clusterTag.setTag(null);

    }
