Introduction Here we will create an example on Spring Data JPA Specification Criteria Query with IN Clause. Spring Data JPA Specification Criteria Query generally used for search functionality on a page where users want to search by giving some inputs or by selecting several dropdown values. In this example we will use how to use collection or list of input parameters into Criteria Query to fetch data from database.

JPA Criteria API
Introduction This tutorial will show you how to use JPA(Java Persistence API) Criteria API Queries for selecting data from database. The Java Persistence API (JPA) is a Java specification for accessing, persisting, and managing data between Java objects / classes and a relational database. The Criteria API is used to define queries for entities and their persistent state by creating query-defining objects. Criteria API queries are written using Java programming language APIs, are typesafe, and are portable. Such queries work regardless of the underlying data store.

Introduction Criteria is a simplified API for retrieving entities by composing Criterion objects. This is a very convenient approach for functionality like “search” screens where there is a variable number of conditions to be placed upon the result set. We will configure hibernate using Java based configuration, for example, we will build SessionFactory with required configurations using Java code. So we won’t use any XML based configuration for this example.
