我有一個奇怪的錯誤與Hibernate3的位置:休眠:爲什麼@OneToMany與列表<MyClass>失敗?
得到了SoftwareDescription類,有以下字段註釋掉的作品就好了堅持它:
@OneToMany
@JoinColumn(name = "id")
private List<SoftwarePrice> prices = new ArrayList<SoftwarePrice>();
得到了這一領域的getter和setter。當我嘗試堅持一個SoftwareDescription,我得到這個錯誤:
"Use of @OneToMany or @ManyToMany targeting an unmapped class: de.abelssoft.domain.SoftwareDescription.prices[de.abelssoft.domain.SoftwarePrice]"
這是我SoftwarePrice - 類:
package de.abelssoft.domain;
//...imports...
@Entity
public class SoftwarePrice implements Serializable{
private static final long serialVersionUID = 8771685731600495299L;
public SoftwarePrice(){}
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;
@Lob
private Currency currency = null;
private SoftwareLicenses license = null;
private double price = 0.0;
//... setters getters...
}
這是我的Hibernate的配置文件:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

</session-factory>

能
人解釋我在這裏沒有看到什麼?
Uhm。好主意,忘了提,但這只是一個枚舉。我在SoftwareDescription.class中獲得了該字段,該字段保持得很好,並且還針對枚舉: private de.abelssoft.domain.SoftwareArchives softwareArchive; – Akku 2010-02-03 13:53:17
