org.hibernate.Criteria a bunch of add(Restrictions) extending org.hibernate.internal.CriteriaImpl


Hi Guys I'm trying to develop a Single Java class which works as a
wrapper of something like of org.hibernate.Criteria to get rid of a
bunch of add(Restrictions) in a elegant way. Here is what I got so far
is a legacy system.


public static void
prepareForSelect(Criteria crit) {

crit.add(Restrictions.eq("cid","1"));

crit.add(Restrictions.eq("did","2");

crit.add(Restrictions.eq("fdl","3")); //omit for brevity
} />

Yes is very inadecuate I know that I'm trying to
implement a java class which extends
org.hibernate.internal.CriteriaImpl and have the properties I need to
restrict and I want to. This class have

This works fine:


public Predicate
toPredicate(Root<Campaign> root,
CriteriaQuery<?>
query, CriteriaBuilder cb) {
return
root.get("campState").get("statusId").in(campStatus);
} />

but i change to :


return
root.get(Campaign_.campState).get(CampState_.campId).in(campStatus). />

And it throws exception:
edit for:
NullPointerException at
org.hibernate.ejb.criteria.path.AbstractPathImpl.get

/>

.

I have seen posts all over the internet that talk about how to fix
the TransientObjectExceptions during save/update/delete but I am
having this problem when calling list on my Criteria.


I
have two objects A and B. A has a field named b which is of type B.
In my mapping b is mapped as a many-to-one. This all runs in a larger
persistence framework (the framework is kind of like Core Data) and so
I don't use any cascades in my hibernate mappings since cascades are
handled at a higher level.


This is the interesting code
surrounding my criteria:


A a = new A();
B b = new
B();
a.setB(b);
session.save("B",

Currently our queries add a variety of Restrictions to ensure the
results are considered active or live. These Restrictions are used in
several places/queries so a method was setup similar to

/> public Criteria addStandardCriteria(Criteria criteria, ...)
{
// Add restrictions, create aliases based on
parameters
// and other non-trivial logic

criteria.add(...);
return criteria;
}
/>

This has worked fine so far, but now this standard criteria needs
to be added to a subquery using DetachedCriteria. Is there a way to
modify this method to accept Criteria or DetachedCriteria or a Better
way
