遞歸HBM映射

Question

我可以在我的HBM映射中執行以下操作嗎？

<class name="Employee" table="employees"> 
    <!-- assume that each person only has exactly one supervisor --> 
    <many-to-one name="supervisor" class="Employee" column="supervisorId" /> 
</class> 

當我使用上述HBM映射，我的服務器拒絕啓動並出現以下錯誤：

org.hibernate.InstantiationException: could not instantiate test object Employee 
Caused by: java.lang.StackOverflowError 
at Employee.<init>(Employee.java:11) 
at Employee.<init>(Employee.java:11) 
at Employee.<init>(Employee.java:11) 
...... (about a hundred duplicates) 

線Employee.java的11只說：

public class Employee implements Serializable { 

應該如何我建模我的主管 - 員工關係？主管沒有專門的POJO，管理對象沒有專門的領域。

Hibernate應該沒有映射這種關係的問題。

它看起來像無限遞歸是錯誤代碼造成的，是這樣的：

public class Employee { 
    private Employee supervisor = new Employee(); 
}
