我有一对一的关系,但hibernatetool在生成模式时抱怨.这是一个显示问题的示例:
@Entity
public class Person {
@Id
public int id;
@OneToOne
public OtherInfo otherInfo;
rest of attributes ...
}

Person与OtherInfo有一对一的关系:
@Entity
public class OtherInfo {
@Id
@OneToOne(mappedBy="otherInfo")
public Person person;
rest of attributes ...
}

人拥有OtherInfo的一面.OtherInfo是拥有的一方,因此人们用来mappedBy在Person中指定属性名称"otherInfo".
使用hibernatetool生成数据库模式时出现以下错误:
org.hibernate.MappingException: Could not determine type for: Person, at table: OtherInfo, for columns: [org.hibernate.mapping.Column(person)]
at org.hibernate.mapping.SimpleValue.getType(SimpleValue.java:292)

知道为什么吗?我做错了什么或者这是一个Hibernate错误?
