hibernate报错：Use of @OneToMany or @ManyToMany targeting an unmapped class:
报错如下：
org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: pp.entity.Employee.departments[pp.entity.Department]
1.hibernate.cfg.xml忘记了：
<session-factory> <mapping class="pp.entity.Department"/> </session-factory>
2.忘记了注解：
@Entity
@Table
public class Department {
//...
}
