rabbitmq初學之連接測試

                                                                           rabbitmq初學之連接測試

    安裝包：otp_win64_17.0.exe（erlang vm）和rabbitmq-server-3.3.1.exe 最後測試成功。
    連接的代碼片段如下

com.rabbitmq.client.ConnectionFactory factory = new com.rabbitmq.client.ConnectionFactory();
factory.setHost("localhost");
factory.setPort(5672);
factory.setUsername("guest");
factory.setPassword("guest");

    默認安裝好rabbitmq就有服務（windows服務），但沒有web監控（localhost:15672）;

    默認的端口就是5672，用戶guest密碼guest，但這個用戶名只能在本機訪問，如果要網絡訪問，需要做用戶管理；

一、【如果寫錯了host （如：factory.setHost("locathost"); ）報錯：】

二、【如果寫錯了HOST的IP（如：factory.setHost("192.168.1.10"); ）無此地址， 報錯：】
