How can I do this using Hibernate

The SQL query is as follows,

select s1.* 
from Sample1 s1,Sample2 s2 where
s1.field1=s2.field4 and
s2.field2='XXYYZZ'

Table Structure

• The table Sample1 has only three fields ( field1, field2, field3 )
• The table Sample2 h开发者_如何转开发as three fields ( field4, field5, field6 )

And the Bean Names are

Sample1Bean, Sample2Bean

I want the data only from the Sample1 only, (field1, field2, field3). How can I do this using Hibernate without HQL and Using Criteria class?

  SELECT s1 FROM Sample1 s1, Sample2 s2 WHERE s1.field1 = s2.field2 AND s2.field2 = 'XXYYZZ'

It will return object of type Sample1 as result.

List s1 = session.createCriteria(Sample1.class)
                 .createCriteria("field1")
                 .add(Restrictions.eq("field2", "XXYYZZ")).
                 .list();

Hibernate make queries on objects not on table. So the association between Sample1 and Sample2 should be mapped.

Obs:

1. s1 will have a list of Sample1.
2. "field1" should be a attribute in Sample1 of type Sample2.
