Query query = entityManager.createQuery("SELECT u FROM User u"); Listusers = query.getResultList();
Query query = entityManager.createQuery("SELECT u FROM User u"); query.setFirstResult(firstResult); query.setMaxResults(maxResults); ListThis example uses the getResultList method to retrieve a paginated list of users from the User entity. The query string "SELECT u FROM User u" selects all the users from the User table and the setFirstResult and setMaxResults methods are used to specify the start position and maximum number of results to return. The getResultList method then returns a list of User objects. The javax.persistence package library is part of the Java Persistence API (JPA) and is provided by the javax.persistence API.users = query.getResultList();
