what is wrong? 在此处输入图片说明

customer.java

@Entity
@Table(name="CUSTOMER")

public class Customer{

    public int customerId;
    public String name;
    public String address;
    public String createdDate;

    @Id
    @Column(name="CUSTOMER_ID", unique = true, nullable = false)
    public int getCustomerId() {
        return customerId;
    }
    public void setCustomerId(int customerId) {
        this.customerId = customerId;
    }
    @Column(name="NAME")
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @Column(name="ADDRESS")
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    @Column(name="CREATED_DATE")
    public String getCreatedDate() {
        return createdDate;
    }
    public void setCreatedDate(String createdDate) {
        this.createdDate = createdDate;
    }



}

CustomerDaoImpl.java

public class CustomerDaoImpl implements ICustomerDao{
    private SessionFactory sessionFactory;
    public SessionFactory getSessionFactory() {
        return sessionFactory;}
    public void setSessionFactory(SessionFactory sessionFactory) {
         this.sessionFactory = sessionFactory;
    }

    public void addCustomer(Customer customer){
        sessionFactory.openSession();
        getSessionFactory().getCurrentSession().save(customer);

    }

    public void updateCustomer(Customer customer){
        sessionFactory.openSession();
        getSessionFactory().getCurrentSession().update(customer);
    }

    public void deleteCustomer(Customer customer){
        sessionFactory.openSession();
        getSessionFactory().getCurrentSession().delete(customer);
    }


    public List<Customer> findAllCustomer(){
        sessionFactory.openSession();

        List list = getSessionFactory().getCurrentSession

().createQuery("from CUSTOMER").list();
        return list;

    }
}

Answer 1

the problem was in my CustomerDaoImpl.java. In the HQL , you should use the java class name and property name of the mapped @Entity instead of the actual table name and column name , so the HQL should be :

List list = getSessionFactory().getCurrentSession().createQuery("from Customer").list();
        return list;
