Can I do the following in my HBM mapping?
<class name="Employee" table="employees">
<!-- assume that each person only has exactly one supervisor -->
<many-to-one name="supervisor" class="Employee" column="supervisorId" />
</class>
When I use the above HBM mapping, my server refuses to start with the following error:
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)
line 11 of Employee.java merely says:
public class Employee implements Serializable {
How should I model my supervisor-employee relationship? There is no special POJO for supervisor and supervisor objects have no special fields.
Hibernate shouldn't have a problem with mapping such a relationship.
It looks like infinite recursion is caused by error in your code, something like this:
public class Employee {
private Employee supervisor = new Employee();
}
