It can create repository implementations automatically, at runtime, from a repository interface. The type of an expression is derived from the structure of the expression, the abstract schema types of the identification variable declarations, the types to which the persistent fields and relationships evaluate, and the types of literals. In this case we cannot use Spring Data JPA repository style method to call stored procedure and we need to call as native query or we need to create StoredProcedureQuery instance from EntityManager.
