JPA CriteriaBuilder Example

Date: 2017-10-23

This tutorial demonstrates using Java Persistence API (JPA) CriteriaBuilder with EclipseLink and MySQL. JPA provides a type-safe alternative to JPQL for creating database queries, particularly useful for dynamic queries built at runtime. The tutorial guides you through creating a Maven project, setting up the database, and implementing the Criteria API to query data. It contrasts the Criteria API's compile-time error checking with the string-based JPQL approach, highlighting the advantages of each. The example uses an Employee entity and shows how to build a query using CriteriaBuilder and CriteriaQuery objects.
