类没有映射异常（但它被映射）？ [英] Class not mapped exception (but it is mapped)?
问题描述
我得到一个类没有映射的异常，但是我想我会映射它！我有2类ClientAppts和Appointments具有1对多的关系。我想获得所有的客户和他们的约会日期。是什么造成的？
以下是课程：
@Entity （name =ClientApps）
@Table（name =person）
public class ClientAppts {
private Integer person_id;
private String fName;
private String lName;
私人日期appt;
私人字符串电话;
private String cell;
私人字符串地址1;
私人字符串地址2;
私人字符串城市;
私有字符串状态;
私人字符串zip;
私人字符串医生;
私人字符串笔记;
@ElementCollection
@CollectionTable（name =Appointment，joinColumns = @JoinColumn（name =person_id））
@Column（name =appt）
收藏<日期>任命;
//接下来有各种各样的getter和setter。
在这里，要明确的是上面提到的Appointment类：
@Entity（name =Appointment）
@Table（name =appointment）
public class约会{
private int id;
私人日期appt;
私人日期apptfinish;
私有字符串标题;
私人字符串位置;
私人BigDecimal费用;
私人BigDecimal amtPaid;
私有布尔serviceRendered;
private int person_id;
私有字符串描述;
以下是引发异常的代码：
列出< ClientAppts> list = getSessionFactory（）。getCurrentSession（）。createQuery（clientApps client order by client.lName）.list（）;

试试这个关系映射：
public class ClientAppts {
...
@OneToMany（mappedBy =clientAppt，fetch = FetchType.LAZY，trgetEntity = Appointment.class）
私人收藏<日期>任命;
...
}
public class Appointment {
...
@ManyToOne
private ClientAppts clientAppt;
...
}
I'm getting a class not mapped exception, however I think I do map it! I have 2 classes ClientAppts and Appointments that have a 1 to many relationship. I want to get all the Clients and their appointment dates. What is causing it? All suggestions welcome.
Here is the class:
@Entity(name="ClientAppts")
@Table(name="person")
public class ClientAppts {
private Integer person_id;
private String fName;
private String lName;
private Date appt;
private String phone;
private String cell;
private String address1;
private String address2;
private String city;
private String state;
private String zip;
private String doctor;
private String notes;
@ElementCollection
@CollectionTable(name="Appointment", joinColumns= @JoinColumn(name="person_id"))
@Column(name="appt")
Collection<Date> appointments;
// various getters and setters follow.
And here, just to be clear, is the Appointment class mentioned above:
@Entity(name="Appointment")
@Table(name="appointment")
public class Appointment {
private int id;
private Date appt;
private Date apptfinish;
private String title;
private String location;
private BigDecimal fee;
private BigDecimal amtPaid;
private Boolean serviceRendered;
private int person_id;
private String description;
And here is the code that throws the exception:
List<ClientAppts> list = getSessionFactory().getCurrentSession().createQuery(" from ClientAppts client order by client.lName ").list();
And finally, the stack trace:

Try this relation mapping:
public class ClientAppts {
...
@OneToMany(mappedBy = "clientAppt", fetch = FetchType.LAZY, trgetEntity = Appointment.class)
private Collection<Date> appointments;
...
}
public class Appointment {
...
@ManyToOne
private ClientAppts clientAppt;
...
}
这篇关于类没有映射异常（但它被映射）？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
