Spring Data MongoDB: java.lang.String cannot be cast to com.mongodb.DBObject

Question

I'm using MongoDB with Spring Data. This query works:

@Query("{ 'user.token' : ?0 }")
List<Event> findByUserKey(String userKey);

But this query does not work and throws "java.lang.String cannot be cast to com.mongodb.DBObject":

@Query("'$or':[ { 'user.token' : ?0 } , { 'user.id' : ?0 } ]")
List<Event> findByUserKey(String userKey);

I think the query is well written, any idea? Thanks.

Query takes a document. Add the parenthesis around the query string.

@Query("{'$or':[ { 'user.token' : ?0 } , { 'user.id' : ?0 } ]}")
List<Event> findByUserKey(String userKey);

You will need spring boot 1.5.2 / spring mongo 1.10.1 version for the placeholder to resolve correctly.
