组织。冬眠QueryException:无法解析属性:abc的查询。def。我的包裹。orm。受雇者

当我试图执行 insertEmployeeDetails 方法:

组织。冬眠QueryException:无法解析属性:abc的查询。def。我的包裹。orm。员工[插入员工(名称、定义,(从公司数据中选择value\u emp\u id,其中testing\u id=1234,COMPANY\u Employee\u id=3345))]

看看类似的关于堆栈溢出的其他帖子,例如,下面的帖子说:

org.hibernate.QueryException: could not resolve property:

那个“ 我们不引用数据库列名,而是引用属性名 name 和 definition 如实体类中所定义 Employee 在下面我试图获取列值的子查询 COLUMN_ID SELECT 应该拉动的子查询 value_emp_id 从…起 COMPANY_DATA 表是我提到的一个SQL查询。这需要修改吗?这可能是这种错误的原因吗?请告知。

Employee.java 具体如下:

package abc.def.mypackage.orm

@Entity
@Table(name = "EMPLOYEE")
public class Employee {
 public int getEmployeeId() {
  return employeeId;
 }

 public void setEmployeeId(int employeeId) {
  this.employeeId = employeeId;
 }

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public int getIsCorrect() {
  return isCorrect;
 }

 public void setIsCorrect(int isCorrect) {
  this.isCorrect = isCorrect;
 }

 public int getIsWrong() {
  return isWrong;
 }

 public void setIsWrong(int isWrong) {
  this.isWrong = isWrong;
 }

 public int getCompanyId() {
  return companyId;
 }

 public void setCompanyId(int companyId) {
  this.companyId = companyId;
 }

 public Integer getTransactionId() {
  return transactionId;
 }

 public void setTransactionId(Integer transactionId) {
 this.transactionId = transactionId;
 }

 public String getDefinition() {
  return definition;
 }

 public void setDefinition(String definition) {
  this.definition = definition;
 }

 @Id
 @Column(name = "EMPLOYEE_ID")
 @GeneratedValue(strategy = GenerationType.AUTO, generator = "seqgen")
 @SequenceGenerator(name = "seqgen", sequenceName = "EMPLOYEE_AUTOINC_SEQ")
 private int employeeId;

 @Column(name = "NAME")
 private String name;

 @Column(name = "DEFINITION")
 private String definition;

 @Column(name = "IS_CORRECT")
 private int isCorrect;

 @Column(name = "IS_WRONG")
 private int isWrong;

 @Column(name = "COMPANY_ID")
 private int companyId;

 @Column(name = "TRANSACTION_ID", nullable = true)
 private Integer transactionId;


}

以下是我在方法中使用HQL的方式:

public boolean insertEmployeeDetails(Employee employee)
    {
        logger.debug("Starting EmployeeDaoImpl.insert()  .....");
        Session session = null;
        Transaction tx = null;
        boolean status = true;
        try {
            session = sessionFactory.openSession();
            tx = session.beginTransaction();
            String hqlInsert = "INSERT INTO Employee (name,definition,"
                    + "( SELECT value_emp_id FROM COMPANY_DATA WHERE testing_id = 1234 AND"
                    + " company_employee_id = 3345))";

            int createdEntities = session.createQuery( hqlInsert )
                    .executeUpdate();

            session.persist(employee);
            tx.commit();
            System.out.println("Checking for hqlInsert");
            System.out.println(hqlInsert);

            System.out.println("Checking for CreatedEntities");
            System.out.println(createdEntities);
        } catch(Exception ex) {
            tx.rollback();
            ex.printStackTrace();
            status = false;
        } finally {
            session.close();
        }
        logger.debug("Completed EmployeeDaoImpl.insert()  .....");
        return status;
    }
