spring boot 获取端口和 Ip

Spring boot  自带监听  实现接口即可在容器启动的时候  启动监听 获取 端口 代码 如下 

import org.springframework.boot.context.embedded.EmbeddedServletContainerInitializedEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;


@Component
public class ConfigDemo implements ApplicationListener<EmbeddedServletContainerInitializedEvent> {

    private int serverPort;

    @Override
    public void onApplicationEvent(EmbeddedServletContainerInitializedEvent event) {
        this.serverPort = event.getEmbeddedServletContainer().getPort();
  
    }

    public int getPort() {
        return this.serverPort;
    }

}

ip 的 获取 如下 

 String host = null;
        try {
            host = InetAddress.getLocalHost().getHostAddress();
        } catch (UnknownHostException e) {
            log.error("get server host Exception e:", e);
        }
