无法使用休眠OGM从mongoDB中删除元素

Question

I am using the following code to remove all the elements from mongoDB collection with a given parent_id :

final String strQuery = "db.Child.remove({'$query':{'PARENT_ID':'" + parentId + "'}})";
                final Query query = entityManager.createNativeQuery(strQuery, Child.class);
                query.executeUpdate();

However, I am getting the following exception:

Unexpected Exception
com.mongodb.util.JSONParseException:
db.Child.remove({'$query':{'CHILD_ID':'7313c076-dbaa-4557-b80f-68d040b65d82'}})

If I replace remove with find , I get the result back. Dont know what is causing JSON parser error in the aboev mentioned native query.

I am using hibernate-ogm version 4.3 Final with mongo-db 3.2

Answer 1

Hibernate OGM 4.3 did not support the remove operation for native queries.

You should give OGM 5.0.2.Final a try: it should solve your issue as we added the support for quite a lot of other operations (and a lot of other fixes and improvements).
