Fix#2 — @DtoRef never checked hasField(): Added requires() to @DtoRef
(same explicit-empty semantics as @DtoPath). DtoMappingReader now
detects a computed association getter and requires an explicit
requires(); DtoMapperWriter's REF case routes computed segments
through extraFetchPaths instead of a broken select(assoc).
Fix#3 — requires() values never validated: Added DtoMappingReader.validateRequiresPath(...), walking every requires() segment against the real property graph (with List unwrapping via a new getterReturnTypeMirror helper). A typo now fails at compile time instead of resurfacing as a runtime PersistenceException. New negative
Fix#4 — bare requires() fetch vs narrowed sibling @DtoPath fetch collision: Traced into Ebean's OrmQueryDetail.fetch(...) and confirmed same-path fetch calls replace, not merge (Map.put). The old dedup logic had priority backwards, silently letting a narrow selection win and drop a computed getter's real dependency. Fixed by prioritizing the full fetch. Proved the regression test was meaningful by reverting the fix and confirming it fails with LazyInitialisationException: Property not loaded: line1, then restored the fix and confirmed it passes.
* #2540 Add DTO mapping from Entity beans via generated mapper code
A large feature, refer to the docs / guides etc. This is a bit like MapStruct in that it generates mapping code via annotation processing but it ALSO creates an optimised FetchGroup for the destination DTO graph and it also implements a generic interface such that it can be fluently used via query.mapTo().
The value is that it automates the mapping code from entity -> dto plus optimises the query used to support building the DTO graph.
Expected to be better to use than MapStruct for ebean orm users.
* Bump ebean-annotation to 8.6 with the dto annotations
* Adjust the build order to via test dependency on ebean-api
