开发小技巧 - springboot项目启动控制台输出访问地址

package com.example.utils;
import cn.hutool.core.util.StrUtil;
import org.springframework.boot.web.context.WebServerApplicationContext;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.*;
/**
 * IP地址工具类
 * @author 李东阳
 */
public class IpAddressUtils {
    /**
     * 获取项目启动的IP地址
     * 注: 仅限springboot项目
     **/
    public static List < String > getIpAddressOfStartUp(WebServerApplicationContext context) {
        List < String > addressList = new ArrayList < > ();
        try {
            Enumeration < NetworkInterface > interfaces = NetworkInterface.getNetworkInterfaces();
            for(NetworkInterface networkInterface: Collections.list(interfaces)) {
                Enumeration < InetAddress > inetAddresses = networkInterface.getInetAddresses();
                for(InetAddress inetAddress: Collections.list(inetAddresses)) {
                    if(!inetAddress.isLoopbackAddress() && inetAddress.isSiteLocalAddress()) {
                        String address = StrUtil.utf8Str(inetAddress.getHostAddress());
                        int port = context.getWebServer().getPort();
                        String ipAddress = StrUtil.format("http://{}:{}", address, port);
                        addressList.add(ipAddress);
                    }
                }
            }
            return addressList;
        } catch (SocketException e) {
            e.printStackTrace();
            return addressList;
        }
    }
}

2、在启动类中使用

package com.example;
import cn.hutool.core.lang.Console;
import com.example.utils.IpAddressUtils;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.context.WebServerApplicationContext;
import org.springframework.context.annotation.Bean;
import java.util.List;
/**
 * 项目启动器
 * @author lidy
 */
@SpringBootApplication
public class BlogApplication {
    public static void main(String[] args) {
        SpringApplication.run(BlogApplication.class, args);
    }
    /**
     * 项目启动输出访问地址
     */
    @Bean
    public ApplicationRunner applicationRunner(WebServerApplicationContext context) {
        return (ApplicationArguments args) - > {
            try {
                Console.log("===============项目启动成功 start===============");
                List < String > ipAddressList = IpAddressUtils.getIpAddressOfStartUp(context);
                ipAddressList.forEach(Console::log);
                Console.log("================项目启动成功 end================");
            } catch (Exception e) {
                e.printStackTrace();
            }
        };
    }
}

注:本案例中使用到了hutool工具来做控制台输出，需要在pom.xml引入如下如下坐标。

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.8.22</version>
</dependency>

如果不想引入相关工具，可以使用其他控制台输出方案即可。
