pojo to hashmap with custom keys

Question

How to convert a java pojo to hashmap( and reverse) not using field names but instead custom keys in an efficient manner. for instance;

Customer:                         
 - name = aaa
 - surname = bbb

will be converted to hashmap with keys below.

Hashmap:
- mykey1 : aaa
- mykey2 : bbb

The solution should be generic and work for different objects (there will be key to property mapping definitions like name -> mykey1, surname->mykey2) I have checked apache commons OGNL but did not quite understand how to get it work for such a situation.
Ps: I know this can be done with reflection, but I am asking a high level solution includings apis and frameworks.

You should use reflection and just for each field find in your properties key and put into map.

It's just one loop, high level solutions use this – VDanyliuk Nov 13 '15 at 08:51
