我正在使用Hibernate3,我有一个包含以下集合的实体:
@ManyToMany
@JoinTable(name = "buys_publishers", joinColumns=@JoinColumn(name="buy_id", referencedColumnName = "buy_id"), inverseJoinColumns=@JoinColumn(name = "publisher_id", referencedColumnName = "publisher_id"))
@OrderBy("name")
private List<Publisher> publishers;
(省略取和级联减速)
目标实体(Publisher)继承自保存激活了@orderby的“name”属性的实体。
这是目标实体:
@Entity
@Table(name="publishers")
@PrimaryKeyJoinColumn(name="account_id")
public class Publisher extends Account{
/**
*
*/
private static final long serialVersionUID = 1L;
@Column(name = "publisher_id")
private Long publisherId;
public Long getPublisherId() {
return publisherId;
}
public void setPublisherId(Long publisherId) {
this.publisherId = publisherId;
}
}
和超级班:
@Entity
@Table(name="accounts")
@Inheritance(strategy=InheritanceType.JOINED)
public abstract class Account implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@Column(name="id",unique=true, nullable=false )
@GeneratedValue( strategy = IDENTITY )
private long id;
@Column(name = "name")
private String name;
@Column(name = "account_type")
@Enumerated(EnumType.ORDINAL)
private AccountType accountType;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public AccountType getAccountType() {
return accountType;
}
public void setAccountType(AccountType accountType) {
this.accountType = accountType;
}
}
Hibernate生成的查询是:
select publishers0_.buy_id as buy1_1_, publishers0_.publisher_id as publisher2_1_, publisher1_.account_id as id6_0_, publisher1_1_.account_type as account2_6_0_, publisher1_1_.name as name6_0_, publisher1_.publisher_id as publisher1_18_0_ from buys_publishers publishers0_ left outer join publishers publisher1_ on publishers0_.publisher_id=publisher1_.publisher_id left outer join accounts publisher1_1_ on publisher1_.account_id=publisher1_1_.id where publishers0_.buy_id=? order by accounts.name asc
从查询中可以清楚地知道,order by应该在publisher1_1_上,我做错了什么或者这是一个错误?
谢谢。
