Query execution problem using Spring and HIbernate together with FLEX - apache-flex

Question

So I'm going to be using Flex 4 with Spring and Hibernate.
Everything is configured and working. I know this as I can do simple queries, like listing all values in a table.
Problem is when I try to perform a 'select' query, then I get all the values, as I was getting before, and not the specific attributes through Select query.
I'm a beginner, so kindly overlook my lack of more technically sound words..but I don use them as I don wanna mis-quote.
Following is some code which will make You understand things better:
This is class used to store data coming from the MySQL database--
package flex;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="intrial1")
public class intrial1 implements Serializable {
#Id #GeneratedValue
#Column( name = "id")
private int id;
#Column( name = "name")
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
This is the class where the sessionFactory does things(too many import statements, just to try to make things work-ignore)--
package flex;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.Query;
import org.hibernate.SessionFactory;
import org.hibernate.annotations.NamedNativeQueries;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.flex.remoting.RemotingDestination;
import org.springframework.flex.remoting.RemotingInclude;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.transaction.annotation.Transactional;
#Repository
#RemotingDestination
public class SpringBean_Service {
private SessionFactory sessionFactory;
#Autowired
public void setSessionFactory(SessionFactory factory) {
sessionFactory = factory;
}
#SuppressWarnings("unchecked")
#RemotingInclude
#Transactional
public List<intrial1> getList() {
return sessionFactory.getCurrentSession().createQuery("from intrial1 ").list();
}
#SuppressWarnings("unchecked")
#RemotingInclude
#Transactional
public List<intrial1> getListAgain() {
org.hibernate.Query q = sessionFactory.getCurrentSession().createQuery("select id from intrial1 where name='chirayu'");
List l = q.list();
return l;
}
#RemotingInclude
#Transactional
public void createFriend(String name, int id) {
intrial1 f = new intrial1();
f.setName(name);
f.setId(id);
sessionFactory.getCurrentSession().save(f);
}
}
In above class, getList() works
perfect, lists all the values. The
createFriend is used to enter values
of id+name, and works smoothly. The
problem is with getListAgain()
function, it gives me a result,
imagine 2 columns, having heading as
'id' and 'name', but listing id values
in both the columns (No names), As You
can understand, I am looking for
result of getListAgain() function as -
"1 column having header as 'id', and
listing id wherever the name
='chirayu'".
Kindly help, as I will need to clear this and move ahead with development.
Thank You.
Regards,
Chirayu
UPDATE NOTE: Would like to say one thing here, if only I make a class as below, which is identical to intrial1 class, but has no return statement for name, i.e., no getName() defined, I get my correct result for the query -
'select id from intrial1 where
name='chirayu''
package flex;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
#Entity
public class intrial2 {
#Id #GeneratedValue
#Column( name = "id")
private int id;
#Column( name = "name")
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
}
Is this strange or meant to be like this. Still looking for answers.

Answer 1

The query
select id from intrial1 where name='chirayu'
doesn't return intrial1 entity, so you should change return type to List or simply change your query to:
from intrial1 where name='chirayu'
