修改前

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.core.env.Environment;

import java.net.InetAddress;

@SpringBootApplication
public class DemoApp {
    public static void main(String[] args)  {
				SpringApplication.run(DemoApp.class, args);
    }
}

 

修改后

import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.core.env.Environment;

import java.net.InetAddress;

        String ip = InetAddress.getLocalHost().getHostAddress();
        String port = env.getProperty("server.port");
        String property = env.getProperty("server.servlet.context-path");
        String path = property == null ? "" :  property;
        System.out.println(
