org.hibernate.MappingException: Unknown entity常见问题(新手需注意)
最近学习Hiberante Annotations时遇到了该问题org.hibernate.MappingException: Unknown entity在baidu和googl上搜寻了 很久也没有找到适合我的解决方法,最后发现是import Entity类造成的(使用Eclipse自动提示导入的该包)
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Transient;
import org.hibernate.annotations.Entity;//这是就出问题了哦
@Entity
@Table(name="test_person")
public class Person implements Serializable
import javax.persistence.Table;
import javax.persistence.Transient;
import org.hibernate.annotations.Entity;//这是就出问题了哦
@Entity
@Table(name="test_person")
public class Person implements Serializable
后面修改了引入的Entity
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Transient;
import javax.persistence.Entity;//引入这个类就正确了
@Entity
@Table(name="test_person")
public class Person implements Serializable
import javax.persistence.Table;
import javax.persistence.Transient;
import javax.persistence.Entity;//引入这个类就正确了
@Entity
@Table(name="test_person")
public class Person implements Serializable
另外有些报org.hibernate.MappingException: Unknown entity,可能是没有在cfg文件中加入 *.hbm.xml造成的
