Usage

From source file:org.jongo.query.BsonQueryFactoryTest.java

@Test
public void canHandlePOJOSerializedAsNumber() throws Exception {

    Mapping mapping = new Mapping.Builder().addSerializer(Coordinate.class, new JsonSerializer<Coordinate>() {
        @Override/*w  w  w.  j av a  2 s . co  m*/
        public void serialize(Coordinate value, JsonGenerator jgen, SerializerProvider provider)
                throws IOException {
            jgen.writeNumber(value.lat);
        }
    }).build();
    QueryFactory customFactory = new BsonQueryFactory(new JacksonEngine(mapping));

    DBObject query = customFactory.createQuery("{coordinate:#}", new Coordinate(1, 1)).toDBObject();

    assertThat(query.get("coordinate")).isEqualTo(1);
}
