本文介绍了如何使用Spring Boot创建一个简单的应用程序，包括SpringApplication的运行，环境变量获取，以及本地和IP访问地址的打印。

SpringBoot启动类

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.core.env.Environment;
import org.springframework.util.StringUtils;

import java.net.InetAddress;
import java.net.UnknownHostException;


@SpringBootApplication
@Slf4j
public class App {
    public static void main(String[] args) throws UnknownHostException {
        ConfigurableApplicationContext application= SpringApplication.run(App.class, args);
        Environment env = application.getEnvironment();
        String ip = InetAddress.getLocalHost().getHostAddress();
        String port = env.getProperty("server.port");
        String path = env.getProperty("server.servlet.context-path");
        if (StringUtils.isEmpty(path)) {
            path = "";
        }
        log.info("\n----------------------------------------------------------\n\t" +
                "本地访问地址: \t\thttp://localhost:" + port + path + "\n\t" +
                "IP访问访问地址: \thttp://" + ip + ":" + port + path + "\n\t" +
                "----------------------------------------------------------");
    }

}
