Spring data mongodb repository findAll field exclusion
Adding an empty filter criteria will do the trick for you:
@Query(value = "{}", fields = "{'objectContentAsJson':0}")Page<ObjectHistory> findAll(Pageable pageable);Apparently, when you do not specify the value parameter to filter results, Spring Data tries to derive a query from the method name and somehow, does not recognize the special meaning of findAll.
Since you are not providing a value field to your @Query annotation, Spring will try to convert the method name findAll to a query which is not respecting the Query Creation Specification from Spring.Please look a the Specs here.
This should work for you :
@Query(value = "{}", fields = "{'objectContentAsJson':0}")Page<ObjectHistory> findAll(Pageable pageable);
