springboot实现获取当前服务器IP及当前项目使用的端口号Port

public class test {
    public static void main(String[] args) throws Exception{
        InetAddress localHost = InetAddress.getLocalHost();
        System.out.println("localhost: " + localHost);
        System.out.println("getHostAddress:  " + localHost.getHostAddress());
        System.out.println("getHostName:  " + localHost.getHostName());
    }
}

server:
  port: 8085

// 配置类 注入port的值
@Configuration
@ConfigurationProperties(prefix = "server")
public class PortConfig {
    @Getter
    @Setter
    private int port;
}

@RestController
public class TestController {

	// 或者使用@Value方式注入
    @Value("${server.port}")
    private int port;

	// 依赖配置
    @Autowired
    private PortConfig portConfig;

    @GetMapping("/test")
    public void test(){
        System.out.println(port);
        System.out.println(portConfig.getPort());
    }
}

if(portConfig.getPort()==0){
	port = 8080;
} else {
	port = portConfig.getPort();
}

或者
int port = portConfig.getPort()>=0?portConfig.getPort():8080;

@RestController
public class TestController {

    @Autowired
    private ServerProperties serverProperties;
    
    @GetMapping("/test")
    public void test(){
        System.out.println(serverProperties.getPort());
    }
}

@RestController
public class ConfigController {
    
    @Autowired
    private ServletWebServerApplicationContext servletWebServerApplicationContext;

    @GetMapping("/testPort")
    public void testPort(){
        System.out.println(servletWebServerApplicationContext.getWebServer().getPort());
    }
}
