RabbitMQ快速入门中创建连接Producer Connection connection = connectionFactory.newConnection();报错解决

小弟在学习RabbitMQ快速入门编写的第一个简单模式案例中,发现报错.

报错原因如下:在http://localhost:15672/#/vhosts创建Add a new virtual host的是的主机名加是 “name”.但在
Producer.class里写的

 //设置虚拟主机名字，默认/
     connectionFactory.setVirtualHost("/name");

多写了一个"/".故在http://localhost:15672/#/vhosts的的name要和Producer.class写的setVirtualHost统一。
