SpringBoot获取项目的ip和端口号

import org.springframework.boot.web.context.WebServerInitializedEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;

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

@Component
public class ServerConfig  implements ApplicationListener<WebServerInitializedEvent> {
    private int serverPort;

    public String getUrl() {
        InetAddress address = null;
        try {
            address = InetAddress.getLocalHost();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        return "http://"+address.getHostAddress() +":"+this.serverPort;
    }

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

}

2、业务层调用

@Autowired
private ServerConfig serverConfig;

public String getUrl() {
   return  serverConfig.getUrl();
}
