在我的Entity类中,我有以下内容,调用一个返回sys_refcursor
的oracle函数 @Entity
@javax.persistence.NamedNativeQuery(name = "getEmp",
query = "{ ? = call getemployees }", resultClass = Employees.class, hints = {
@javax.persistence.QueryHint(name = "org.hibernate.callable", value = "true") })
@Table(name = "EMPLOYEES")
public class Employees {
在DAO我有
@Inject
private SessionFactory sessionFactory;
@Override
public List<Employees> getEmployees() {
List query = new ArrayList<Employees>();
try{
query = sessionFactory.getCurrentSession()
.getNamedQuery("getEmp").list();
}
catch(Exception e){
System.out.println("exception "+e.getMessage());
e.printStackTrace();
}
return query;
}
但是当我运行我的应用程序时,我收到以下异常
exception命名查询未知:getEmp SEVERE:org.hibernate.MappingException:未知的命名查询:getEmp 在org.hibernate.internal.AbstractSessionImpl.getNamedQuery(AbstractSessionImpl.java:149) 在org.hibernate.internal.SessionImpl.getNamedQuery(SessionImpl.java:1257) at net.test.employees.dao.EmployeesDAO.getEmployees(EmployeesDAO.java:34) at net.test.employees.service.EmployeesService.getEmployees(EmployeesService.java:24)
如何解决此问题?任何帮助都非常值得赞赏。

我已通过在 applicationContext.xml 中添加以下内容来解决此问题。
<property name="annotatedClasses">
<list>
<value>net.test.model.Employees</value>
</list>
</property>
