Currently Hibernate supports return type *Map<String,String>* but it does not support *Map<String,Object>.*
*Example:*
{code}class User {
long id;
String imageUrl;
Address address;
//remaining mapping attributes
.
.
.
}
class Address {
String name;
}{code}
*My Criteria Query:*
{code}CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Tuple> cq = builder.createTupleQuery();
Root<User> root = cq.from(User.class);
cq.multiselect(
root.get("imageUrl"),
root.get("address"));
cq.where(builder.equal(root.get("id"),3));
Tuple tuple = entityManager.createQuery(cq).getSingleResult();
tuple.get(0);
// Error occurs for below code. (Stack over flow exception)
tuple.get(1);{code}
While getting {{imageUrl}} there is no error but when it tries to fetch {{address}} \[Address type not string] attribute hibernate triggers stack over flow exception because it was trying to convert address to string.
