Example
You can use this utility to map your native SQL resultList to a List of Pojo.
class Employee {
String id;
String firstName;
String lastName;
String email;
String department;
Date doj;
boolean active;
}
class EmployeeRepository {
@PersistenceContext
private EntityManager em;
public List<Employee> getActiveEmployeeList(){
Query queryString = em.createNativeQuery("select firstName, lastName, email from employee where active=1");
List<Object[]> resultList = queryString.getResultList();
// build a list of columns (should be in same order as select query)
String[] columns = {"firstName","lastName","email"};
List<Employee> response = NativeSQLHelper
.mapToModel(resultList, Employee.class, columns);
return response;
}
}
