+     *
+     *      1、引入依赖：
+     *          <dependency>
+     *             <groupId>org.springframework.cloud</groupId>
+     *             <artifactId>spring-cloud-commons</artifactId>
+     *             <version>${version}</version>
+     *         </dependency>
+     *
+     *      2、配置文件，或者容器启动变量
+     *          spring.cloud.inetutils.preferred-networks: 'xxx.xxx.xxx.'
+     *
+     *      3、获取IP
+     *          String ip_ = inetUtils.findFirstNonLoopbackHostInfo().getIpAddress();
