A Spring-Data-JPA Enthusiast has created a project that implements projections with specifications. I am using it in my own project without problem. You may check it from here:

https://github.com/pramoth/specification-with-projection

Update for database level projections

There is an outdated comment below.

Is not query optimized. It just map the results after they have been queried

The last version of this library supports database level projections link to the commit.

Update for the last Spring Boot versions

Until this pull request is not merged, to support the last Spring Boot versions, fixed library sources can be copy pasted directly to the project from here https://github.com/v-ladynev/specification-with-projection-embeded
