Yes, your JPA Criteria can be easy. All you need to do is to add uaiCriteria in your implementation.

Imagine that you want to run the following JPQL:

select p from Person p 

If you want do write the JPQL above using only the JPA native Criteira, you should do something like:

 CriteriaQuery<Person> criteriaQuery = criteriaBuilder.createQuery(Person.class);
 Root<Person> root = criteriaQuery.from(Person.class);
 criteriaQuery.select(root);
 TypedQuery<Person> query = entityManager.createQuery(criteriaQuery);
 query.getResultList();

With uaiCriteria you could run like this:

UaiCriteria<Person> easyCriteria = UaiCriteriaFactory.createQueryCriteria(entityManager, Person.class);
uaiCriteria.getResultList();

To create a code like the code above, add the maven dependency below:

<dependency>
    <groupId>uaihebert.com</groupId>
    <artifactId>uaiCriteria</artifactId>
    <version>4.0.0</version>
</dependency>

Now, criteria is easy to use! ;)

You have the following mvn commands available:

• if you want to build the project run: mvn clean package
• if you want to test the project run: mvn clean test
• if you want to generate the cobertura report use: mvn cobertura:clean cobertura:cobertura
  • the generated report can be found at: <uaiCriteria_FOLDER>/target/site/cobertura/index.html
• if you have a sonar server you will be able to create a report by doing mvn sonar:sonar
