How To Use JPA Named Queries Via orm.xml File And Spring Projection (DTO)

Description: This application is an example of combining JPA named queries listed in orm.xml file and Spring projections (DTO). For queries names we use the {EntityName}.{RepositoryMethodName} naming convention. This convention allows us to create in the repository interface methods with the same name as of named query.

Key points:

• define the named queries in orm.xml file in a folder named META-INF the application classpath
• define the proper Spring projection
