RABBITMQ Beginner's connection test

Recently engaged in the interface, need to use the RABBITMQ, the company engaged in an afternoon or not connected, and then a closer look at the English explanation, test connection success, the following error points.

I used the installation package: Otp_win64_17.0.exe (Erlang vm) and Rabbitmq-server-3.3.1.exe last tested successfully.

The code snippet for the connection is as follows

Com.rabbitmq.client.ConnectionFactory factory = new Com.rabbitmq.client.ConnectionFactory ();
Factory.sethost ("localhost");
Factory.setport (5672);
Factory.setusername ("Guest");
Factory.setpassword ("Guest");

The default installation is RABBITMQ service (Windows service), but no web monitoring (localhost:15672);

The default port is 5672, the user guest password guest, but this user name only in the local access, if you want to network access, need to do user management;

1, if write the wrong host (such as: Factory.sethost ("Locathost"); Error

May be a master to see will laugh, so simple things to engage in half a day, but I am not a master, write to their own record.
