How to I update property table reffered in mybatis

Question

Strange I couldn't find this easy answer in stackoverflow or mybatis guide. Thank you for those who is trying to help.

I have a class like this

Class One {
String name;
}

Class Two {
String name2;
One one;
}

I am using MyBatis @Update annotaion.

@Update("UPDATE One SET " +
            "name=#{name}")
int updatefirst(Two two);

@Update("UPDATE Two SET " +
            "name2=#{name}")
int updatesecondname(Two two);

How do I include the inner property that updates the foreign table one from the above query when I call updatesecondname?

Any help greatly appreciated.
