I use field Updator to keep Class User's updator, Updator itself is of Class User:
Class User{
...
User updator;
}
This makes a recursive problem which may cost a lot memory(Do not know how hibernate solve such recursive prolbem).I tried a method, make a new class SimpleUser to be the updator which itself don't have a updator:
Class SimpleUser{
...
}
Class User extends SimpleUser{
...
SimpleUser updator;
}
But sometimes I got WrongClassException. How to solve such problem?

Isn't there someone meet the same problem,I do think this is a common issue ,what to do if User's updator is also a User, is recursive OK here?

<hibernate-mapping>
<class
name="com.plaza.dal.model.User"
table="T_USER"
>
<id
name="id"
type="java.lang.Long"
column="ID"
>
<generator class="sequence">
<param name="sequence">SE_T_USER</param>
</generator>
</id>
<many-to-one
name="updator"
class="com.plaza.dal.model.User"
column="UPDATOR"
/>
</class>
</hibernate-mapping>
hibernate mapping is above,someone help.
