Spring boot - how to get running port and ip address
提问by Jessie
I am passing the port via shell script while starting the spring boot application. Would like to know how to get the running port and system ip address in the application to print in log file.
我在启动 spring 启动应用程序时通过 shell 脚本传递端口。想知道如何在应用程序中获取运行端口和系统IP地址以打印在日志文件中。
script: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9890
脚本：-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9890

If you want to get it after application running try with this:
如果你想在应用程序运行后得到它，试试这个：
@Component
public class ApplicationLoader implements ApplicationRunner {
@Autowired
private Environment environment;
@Override
public void run(ApplicationArguments args) throws Exception {
System.out.println(environment.getProperty("java.rmi.server.hostname"));
System.out.println(environment.getProperty("local.server.port"));
System.out.println(InetAddress.getLocalHost().getHostAddress());
}
}
You can get port many ways:
您可以通过多种方式获取端口：
@Value("${local.server.port}")
private int serverPort;
or
或者
@LocalServerPort
private int serverPort;

You can autowire port number in any component class in following way
您可以通过以下方式在任何组件类中自动装配端口号
// Inject which port we were assigned
@Value("${local.server.port}")
int port;
Or with the annotation @LocalServerPort
或者用注释 @LocalServerPort
@LocalServerPort
private int port;
And host address with following
和主机地址如下
String ip = InetAddress.getLocalHost().getHostAddress()

When you pass any parameters from the script, you can get this at runtime:
当你从脚本中传递任何参数时，你可以在运行时得到这个：
private String jmxRemote = System.getProperty("com.sun.management.jmxremote");
private String jmxRemotePort = System.getProperty("com.sun.management.jmxremote.port");
Get properties either the JVM itself or any -D options you may have passed at the command line
获取 JVM 本身或您可能在命令行中传递的任何 -D 选项的属性
Get ip:
获取ip：
// for example 127.0.0.1 is localhost ip
private String ip = InetAddress.getLoopbackAddress().getHostAddress();
Get port:
获取端口：
@Value("${local.server.port}")
private int serverPort;
or by:
或通过：
@LocalServerPort
private int serverPort;
or by:
或通过：
@Autowired
private Environment environment;
public void doWork(){
String serverPort = environment.getProperty("local.server.port");
// do something
}
Also you can get all properties from Environment - JVM / system / environment / all passed arguments
您还可以从 Environment - JVM / system / environment / 所有传递的参数中获取所有属性
