Same query method and parameters with different return in Spring Data

问题

I want to use projections in order to return less elements for the same queries.

Page<Network> findByIdIn(List<Long> ids);
Page<NetworkSimple> findByIdIn(List<Long> ids);

Since the queries are created using the name of the method, what options do I have to do the same query but with different name ?

回答1:

Spring Data query via method is constructed by convention and you can't change the name and yet expecting a same behavior.

You can try to use @Query annotations which doesn't depend on the method name, or possibly implementing custom DAO using JPAQuery plus FactoryExpression which has the same effect as projections.
