Question

以下是我的客户类DTO对象。当我在hibernate上进行一些查询时，我收到1064错误

@Entity
@Table(name="customer")
public class Customer implements Serializable{

/**
 * 
 */
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue
private int id;

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

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

@Column(name="phone1")
private String phone1;

@Column(name="phone2")
private String phone2;

@Column(name="credit_limit")
private BigDecimal creditLimit;

@Column(name="current_credit")
private BigDecimal currentCredit;

@OneToMany(fetch=FetchType.EAGER)
@JoinColumn(name="customer_id")
private Set<Order> orders;}

然后我调用以下方法

public List<Order> allOrders(){
    return orderDao.findAll();
}

这是我收到的错误。

    orders0_.id as id1_1_1_,
    orders0_.customer_id as customer2_1_1_ 
from

order orders0_ where
    orders0_.customer_id=?

你能说出我在这里做错了吗

Answer 1

问题是你的Order实体：order是sql中的保留字。最好是将表名更改为其他名称，例如@Table(name = "orders") - s。

或者，请参阅this回答：

如果您使用的是Hibernate 3.5+，请尝试 hibernate.globally_quoted_identifiers = true引用所有数据库标识符（这是他们为JPA 2.0添加的内容，请参阅secion 2.13如果使用JPA，JPA命名的数据库对象的命名为JPA方式激活它。

在oneToMany映射上接收错误：1064
