我在Mysql数据库中创建了SQL视图。我正在使用基于用户搜索条目的JPA编写Web服务以显示列表。 Hibernate查询在控制台中正确执行，但在advaced rest client中检查时未显示列表。请在下方查看所需代码：
实体类：
@Entity
@Table(name = "tbi_datadiscovery_detail_view"/*, catalog = "timebound"*/)
public class TbiDDDetailView implements java.io.Serializable {
// Fields
@Id
@Column(name = "dd_metric_id")
@GeneratedValue(generator = "gen")
@GenericGenerator(name = "gen", strategy = "foreign", parameters = @Parameter(name = "property", value = "ddConfigId"))
private Integer ddConfigId;
@Column(name="dd_metric_name")
private String metricName;
@Column(name="dd_type")
private String ddType;
@Column(name="dd_name")
private String ddName;
@Column(name="discovery_id")
private Integer discoveryId;
@Column(name="key_words")
private String keywords;
@OneToOne
@PrimaryKeyJoinColumn
private TbiDDConfigMaster tbiDDConfigMaster;
//setters & getters
}
JPA存储库：
public interface TbiDDDetailViewDao extends CrudRepository<TbiDDDetailView, Integer>, JpaRepository<TbiDDDetailView, Integer> {
@Query("select v from TbiDDDetailView v,TbiDDConfigMaster t where v.ddConfigId = t.ddConfigId and t.domainId=?1 and v.metricName LIKE %?2% or t.keywords LIKE %?2%")
List<TbiDDDetailView> findByDomainIdAndMetricNameLike(Integer domainId,String metricName);
}
服务实施：
public TbiDDDetailViewListResponse getViewMatrics(List sortProperties, List sortTypes,
List operator, List value, List property, int page, int limit,
Integer domainId, String searchString) {
TbiDDDetailViewListResponse res = new TbiDDDetailViewListResponse();
List<TbiDDDetailView> tbiDDDetailViews = tbiDDDetailViewDao.findByDomainIdAndMetricNameLike(domainId, searchString);
CriteriaBuilder cb=em.getCriteriaBuilder();
CriteriaQuery<TbiDDDetailView> qry =cb.createQuery(TbiDDDetailView.class);
Root root = qry.from(TbiDDDetailView.class);
Root config = qry.from(TbiDDConfigMaster.class);
List creteriaList = new ArrayList<>();
Predicate predicate1 = cb.equal(root.get("tbiDDConfigMaster").get("ddConfigId"), config.get("ddConfigId"));
creteriaList.add(predicate1);
Predicate predicate2 = cb.equal(root.get("tbiDDConfigMaster").get("ddConfigId"), domainId);
creteriaList.add(predicate2);
Predicate predicate3 = cb.like(cb.upper(root.get("metricName")),searchString);
creteriaList.add(predicate3);
CriteriaQuery<TbiDDDetailView> criteriaQuery = qry.select(cb.construct(TbiDDDetailView.class, root.get("ddConfigId"),root.get("metricName"),root.get("ddType"),
root.get("ddName"),root.get("discoveryId")));
List<Order> orderList = new ArrayList<>();
orderList = getSort(cb,root,sortProperties, sortTypes, null);
qry.where(cb.and((Predicate[]) creteriaList.toArray(new Predicate[0])));
int start=0;
if(limit != 0)
start=(page-1)*limit;
TypedQuery<TbiDDDetailView> tq = em.createQuery(qry);
tbiDDDetailViews = tq.setFirstResult(start).setMaxResults(limit).getResultList();
TypedQuery<TbiDDDetailView> queryTotal = em.createQuery(criteriaQuery);
long totalRecords = (long) queryTotal.getResultList().size();
List<DDDetailViewResponse> details = new ArrayList<>();
if(tbiDDDetailViews!=null)
{
for(TbiDDDetailView t : tbiDDDetailViews){
DDDetailViewResponse detailView = new DDDetailViewResponse();
detailView.setDdMetricId(t.getDdConfigId());
detailView.setDdMetricName(t.getMetricName());
detailView.setDdType(t.getDdType());
detailView.setDdName(t.getDdName());
detailView.setDiscoveryId(t.getDiscoveryId());
details.add(detailView);
System.out.println("name-->"+t.getDdName()+"------type-------"+t.getDdType()+"-------------id--------------"+t.getDdConfigId()+"---------Metricname-----------"+t.getMetricName());
}
}
res.setRecords(details);
res.setPageNumber(page);
if(limit != 0) {
int Rem = (totalRecords%limit)>0?new Integer(1):0;
int total = (int) (totalRecords/limit + Rem);
res.setTotalPages(total);
log.info("TotalRecords :"+totalRecords + "Total Pages:" +total);
}
return res;
}
当我使用调试模式检查时，执行不会仅进入for循环，它直接循环出来。
在控制台中执行Hibernate查询：
