I am not getting the JSON response I need, so it is difficult to use it through AngularJS. Below is the code and required output.
@Enity
@Table(name = "[empinfo]", schema = "[dbo]" )
public class salsum {
public String location
public String dept;
public double salary;
}
public class salDAO{
public static List<salsum> gsummary(){
EntityManagerFactory emf = Persistence.createEntityManagerFactory("defaultPersistenceUnit");
EntityManager em = emf.createEntityManager();
EntityTransaction txn = em.getTransaction();
txn.begin();
Query query = em.createQuery("SELECT e.location, e.dept, e.salary FROM salsum e");
List<salsum> salSum= query.getResultList();
txn.commit();
return salSum;
}
}
public class Application extends Controller {
@Transactional
public Result SalarySumJson()
{
// return ok(Json.toJson(salDAO.gsummary()));
Gson gson = new Gson();
return ok(gson.toJson(salDAO.gsummary()));
}
}
I am getting the output after calling DAO :
{0: "Chicago", 1:"HR", 2: 20000}
{0: "Landon", 1:"HR", 2: 30000}
{0: "New York", 1:"HR", 2: 10000}
How can I get the below output :
{"location": "Chicago", "dept": "HR", "salary": 20000}
{"location": "Landon", "dept": "HR", "salary": 30000}
{"location": "New York", "dept":"HR", "salary": 10000}
Thanks and Regards,

I believe you need to try to add the @SerializedName() annotation to your "salsum" class like so:
@Entity
@Table(name = "[empinfo]", schema = "[dbo]" )
public class salsum {
@SerializedName("location")
public String location;
@SerializedName("dept")
public String dept;
@SerializedName("salary")
public double salary;
}
Hope this helps. Please see this for more information:
Problem is resolved. I have made following changes in above code :
Add constructor in model class :
@Enity
@Table(name = "[empinfo]", schema = "[dbo]" )
public class salsum {
public String location
public String dept;
public double salary;
public salsum(String location, String dept, double salary)
{this.location = location;
this.dept = this.dept;
this.salary = this.salary;
}
}
and in query add new :
Query query = em.createQuery("SELECT new salsum(e.location, e.dept, e.salary) FROM salsum e");
Thanks and Regards,
