JPA query for a JSONB column in Postgres

Question

I'm trying to create a query with JPA for a JSONB column in a Postgres DB. The query will pretty much look like this example from the Postgres JSON Documentation :

-- Find documents in which the key "company" has value "Magnafone"
SELECT jdoc->'guid', jdoc->'name' FROM api WHERE jdoc @> '{"company": "Magnafone"}';

where jdoc is the JSONB column in table api .

So far executing this query is easy and not a problem. However if I try to parameterize the query I'm stuck.

Here are a few queries I've tried:

1) This does not work, because the ? is not recognized between the '-signs:

String name= "Magnafone";

JPA.em().createNativeQuery("SELECT jdoc FROM api
WHERE jdoc @> '{\"name\": ?}'", Record.class)
.setParameter(1, name)

Error:

2) I've found this in another SO-Thread. Does not work though, because the || shows up in the query and throws an SQL Exception.

JPA.em().createNativeQuery("SELECT jdoc FROM api 
WHERE jdoc @> '{\"name\": ' || :name ||'}'", Record.class)
.setParameter("name", name)

I've tried a few other things that made Postgres or JPA throw up in one or another way and didn't manage to get the JSON Parameter while using the parameterization from JPA.

3)

JPA.em().createNativeQuery("SELECT jdoc FROM api 
WHERE jdoc @> '{\"name\": ' || ? ||'}'", Record.class)
.setParameter(1", name)

FYI: This works (don't worry, I'm not using it):

JPA.em().createNativeQuery("SELECT jdoc->'guid', jdoc->'name' FROM api 
WHERE jdoc @> '{\"company\": \""+company+"\"}'", Record.class)

Also: I'm using the createNativeQuery because the @> -Operator is not recognized by JPA.

Thanks.

pozs posted the Answer as a comment:

Try "... WHERE jdoc @> cast('{\\"company\\":' || to_json(cast(? as text)) || '}' as json)" (or jsonb at the last cast, if that's appropriate).
