Embedable类

} 


Entity Class 

@Entity 
@Table(name = "SA_TASK_INTERFACES") 
public class WorkFlowTaskInterface2Entity extends BaseEntity { 
    private SaTaskInterfacesId id; 
// private Long saWorkflowRules; 
    private Short sortOrder; 
    private String itemCsv; 
    private String personCodeCsv; 


    // Property accessors 
    @EmbeddedId 
    @AttributeOverrides({ 
    @AttributeOverride(name = "processRuleId", column = @Column(name = "PROCESS_RULE_ID")), 
    @AttributeOverride(name = "interfaceCode", column = @Column(name = "INTERFACE_CODE")) }) 
    public SaTaskInterfacesId getId() { 
    return this.id; 
    } 

    public void setId(SaTaskInterfacesId id) { 
    this.id = id; 
    } 


    @Column(name = "SORT_ORDER") 
    public Short getSortOrder() { 
    return this.sortOrder; 
    } 

    public void setSortOrder(Short sortOrder) { 
    this.sortOrder = sortOrder; 
    } 

    @Column(name = "ITEM_CSV", length = 50) 
    public String getItemCsv() { 
    return this.itemCsv; 
    } 

    public void setItemCsv(String itemCsv) { 
    this.itemCsv = itemCsv; 
    } 

    @Column(name = "PERSON_CODE_CSV", length = 150) 
    public String getPersonCodeCsv() { 
    return this.personCodeCsv;

Deletion Query Sample 

    public void taskInterfaceDeletion(WorkFlowTaskInterface2Entity workFlowTaskInterface2Entity) { 

     baseORMDao.executeQuery("DELETE FROM WorkFlowTaskInterface2Entity entity WHERE entity.interfaceCode="+(long)58+" AND entity.processRuleId="+(long)112301+""); 

    } 

错误是一个实体排：

无法解析属性：的interfaceCode：pk.gov.fbr.insys.entity.workflow.WorkFlowTaskInterface2Entity [删除FROM pk.gov.fbr.insys.entity.workflow.WorkFlowTaskInterface2Entity entity WHERE entity.interfaceCode = 58 AND entity.processRuleId = 112301];嵌套异常是org.hibernate.QueryException：无法解析属性：interfaceCode：pk.gov.fbr.insys.entity.workflow.WorkFlowTaskInterface2Entity [从pk.gov.fbr.insys.entity.workflow.WorkFlowTaskInterface2删除实体。实体WHERE实体。 interfaceCode = 58 AND entity.processRuleId = 112301]

Answer 1

这里的问题非常讨人喜欢，从stacktrace。 interfaceCode属性在SaTaskInterfacesId中声明，并且此类不属于WorkFlowTaskInterface2Entity的父类，因此未找到该属性。
