java - 如何在Java中获取RabbitMQ的当前IP地址？

Question

我有一个带有地址列表的connectionFactory(org.springframework.amqp.rabbit.connection)

    @Bean(name = "mainConnectionFactory")
    @Primary
    public ConnectionFactory mainConnectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        String addresses = rabbitmqHost_main + ":" + rabbitmqPort_main + ", " + rabbitmqHost_reserve + ":" + rabbitmqPort_reserve;;
        connectionFactory.setVirtualHost(rabbitmqVirtualHost_main);
        connectionFactory.setUsername(rabbitmqUsername_main);
        connectionFactory.setPassword(rabbitmqPassword_main);
        connectionFactory.setAddresses(addresses);
        return connectionFactory;
    }

我的应用程序会定期自动重新连接到其中一台服务器。如何在Java中获取当前服务器的IP地址？

Answer 1

可以使用类似的方法从运行程序的服务器获取主机名

try {
            InetAddress addr;
            addr = InetAddress.getLocalHost();
            hostname = addr.getHostName();
        } catch (UnknownHostException ex) {
            LOGGER.error("Hostname can not be resolved");
        }
