@SpringBootApplication

public class App {

public static void main(String[] args) {

ConfigurableApplicationContext context=SpringApplication.run(App.class, args);

//方法1: 直接使用AppicationContext.getEnvironment System.out.println(context.getEnvironment().getProperty("local.ip"));

context.getBean(UserConfig.class).show();

context.close();

}

}

@Component

public class UserConfig {

//方法3：注解获取 

@Value("${local.port}")

private String localPort;

//方法2: 在配置类中注入Environment 使用.getProperties调用 

@Autowired

private Environment env;

public  void show() {

System.out.println("local.ip:"+env.getProperty("local.ip"));

System.out.println("local.port:"+localPort);
