Consider EntityGraph argument for query methods

[mp911de]

It would be neat to provide an entity graph to a query method through a Spring Data JPA type allowing:

• Declaration through typed property paths (e.g. EntityGraphHint.fetch(Person::getFirstName, Person::getAddress, …))
• From a named entity graph reference (EntityGraphHint.fetch("my-named-graph"), EntityGraphHint.load("my-named-graph"))
• From a EntityGraph object (EntityGraphHint.fetch(obj), EntityGraphHint.load(obj))

Within this ticket, we should also consider the following changes:

• Add support for combining @EntityGraph and Specification<T> [DATAJPA-1824] #2113
• Support @EntityGraph for default methods that invoking underlying findAll [DATAJPA-1431] #1746
• EntityGraph and QueryDSL not working together [DATAJPA-988] #1334

@mp911de Hi, I’d like to work on this issue.
Is anyone currently working on it? If not, may I take it?
