我是 Spring Boot 和 Hibernate 的新手。在这里，我尝试运行基于搜索的可选参数查询，我可以按名称、国家/地区等进行搜索。如果我将此字段保留为空，则查询应该全部列出。但问题是我的方法返回所有数据，忽略我的搜索参数。我的模型类看起来像

@Entity(name="MLFM_ORDER_OWNER")
public class ModelOrderOwner {

    @Id @GenericGenerator(name = "custom_sequence", strategy = 
            "com.biziitech.mlfm.IdGenerator")
    @GeneratedValue(generator = "custom_sequence")
    @Column(name="ORDER_OWNER_ID")
    private Long orderOwnerId;

    @Column(name="OWNER_NAME")
    private String ownerName;

    @OneToOne
    @JoinColumn(name="BUSINESS_TYPE_ID")
    private ModelBusinessType businessTypeId;

    @Column(name="SHORT_CODE")
    private String shortCode;


    @ManyToOne
    @JoinColumn(name="OWNER_COUNTRY")
    private ModelCountry ownerCountry;
// getter setter..

我的存储库界面看起来像

public interface OrderOwnerRepository extends 

    JpaRepository<ModelOrderOwner,Long>{
        @Query("select a from MLFM_ORDER_OWNER a where a.businessTypeId.typeId=coalsec(:typeId,a.businessTypeId.typeId) and a.ownerCountry.countryId=coalsec(:countryId,a.ownerCountry.countryId) and a.ownerName LIKE %:name and a.shortCode LIKE %:code")
        public List <ModelOrderOwner> findOwnerDetails(@Param("typeId")Long typeId,@Param("countryId")Long countryId,@Param("name")String name,@Param("code")String code);

    }

这是我在控制器中的方法

@RequestMapping(path="/owners/search") …
