java - Updating to mongo 3.0 -
i working on mongo 2.x , have updated mongo 3.x updated java mongodb client 3.0.3, have js on mongo server needs executed , js requires 2 object parameters done in previous version this:
db database = mongoclient.getdb(db); commandresult cr = database.doeval(js, query, collection); // js string, query basicdbobject , collection list<string>
need in running same in place of db getting mongodatabase (as getdb has been deprecated) , doeval replaced runcommand
you can in code of original doeval method figure out how this, looks like:
public commandresult doeval(final string code, final object... args) { dbobject commanddocument = new basicdbobject("$eval", code).append("args", arrays.aslist(args)); return executecommand(wrap(commanddocument)); }
that means you'll need like:
document commanddocument = new document("$eval", code).append("args", arrays.aslist(args)); return runcommand(commanddocument);
note running scripts on server application code not recommended, you're better off translating java code, driver has more efficient support this.
