注意检查是不是端口设置错误了

端口应该是 5672 不是15672

		// 1. 创建连接工程
		ConnectionFactory connectionFactory = new ConnectionFactory();
		connectionFactory.setHost("121.89.219.240");
		connectionFactory.setPort(5672);
		connectionFactory.setVirtualHost("/");
		connectionFactory.setUsername("admin");
		connectionFactory.setPassword("admin");
