Hi Jeff,
Thanks for the tip. Is this the general idea?
public Object createInstance(String stmtId, Class clazz) {
String className = clazz.getName();
if (className.startsWith("com.test.model.abator")) {
className = className.replaceFirst("\.abator","");
Object obj = Resources.instantiate(className);
return obj;
}
return null;
}
So the sqlMap file would still say:
resultMap class="com.test.model.abator.Account"
but would actually return a com.test.model.Account object?
This seems like a good solution, although the "magic" of that class
conversion seems a little opaque if someone else had to maintain the
code. I guess commenting heavily could help. Do you know of any
non-ibatis specific way to create a subclass from an instance of a
superclass?
Thanks for the help,
Dave
