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

NullPointerException at org.hibernate.ejb.criteria.path.AbstractPathImpl.get
Programming Languages

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


.

org.hibernate.TransientObjectException during Criteria.list()
Programming Languages

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",

Hibernate Criteria: Add restrictions to Criteria and DetachedCriteria
Programming Languages

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
