how to execute mongo admin command from java

I want to execute soem admin command with parameters from java.

The commands are:

{ enablesharding : "test" }
{ shardcollection : "test.test_collection", key : {"number":1} }

How can I do it from java driver?

The following code doesn't works:

mongo.getDb("admin").command("{shardcollection : \"test.test_collection\", key:\"number\":1} }")
Solution

  • I just found it 

    DB db = mongo.getDB("admin");
DBObject cmd = new BasicDBObject();
cmd.put("shardcollection", "testDB.x");
cmd.put("key", new BasicDBObject("userId", 1));
CommandResult result = db.command(cmd);
