A CriteriaBuilder is used to build a CriteriaQuery objects which is then used to perform a query such as in this example from the Java Persistence wikibook: // Query for a List of If you are writing Unit Tests then you should probably mock the call to findAll() method of articleRepository Class using a mocking framework like Mockito or PowerMock. Although the Specification class is designed to handle where clauses, specifying group by clause within the Specification class also works. – Spring Data JPA supports a variable called entityName. This is the way I did to collect data from multiple entities (custom Select). To retrieve only slices of data, Spring Data uses the pagination abstraction which comes with a Pageable interface on the requesting side as well as a Page abstraction on the result side of things.

Improve this Spring Data JPA or JPA stands for Java Persistence API, so before looking into that, we must know about ORM (Object Relation Mapping). The Specification interface in Spring Data JPA is a powerful tool that allows developers to build dynamic queries with criteria-based predicates. 2. If we need to fetch an entity with different associations, we need to specify a DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema. If you have more time to invest, this is a good article about static metamodel: Dynamic, typesafe queries in JPA 2. How to use Criteria in JPA in Spring boot? 2. Spring Data JPA provides many ways to deal with entities, including query methods and custom JPQL queries. This is just an example to search all pets whose at least one owner has name equal to ownerName But you could add a method List<Pet> findByOwnersNameOrderByIdDesc(String ownerName); in your repository instead (as an equivalent to Specification).
