How To Use Spring Projections(DTOs) And Inclusive Full Joins (MySQL)

Description: This application is a proof of concept for using Spring Projections(DTO) and inclusive full joins written in native SQL (for MySQL).

Key points:

• define two entities (e.g., Author and Book in a lazy bidirectional @OneToMany relationship)
• populate the database with some test data (e.g., check the file resources/data-mysql.sql)
• write interfaces (projections) that contains getters for the columns that should be fetched from the database (e.g., check AuthorNameBookTitle.java)
• write inclusive full joins queries using native SQL
