使用 Environment 接口获取

使用 Environment.getProperty() 配置文件值

例如 获取当前 系统端口号的配置文件值 server.port

Environment 接口需要 获取Bean方式使用

final Environment environment = applicationContext.getBean(Environment.class);
		
// 服务端口
final String port = environment.getProperty("server.port");

Sysout.out.println(String.format("端口号：%s", port))

	    final ConfigurableApplicationContext applicationContext = SpringApplication.run(Application.class, args);
		
	    final Environment environment = applicationContext.getBean(Environment.class);
		
	    final String profilesActive = environment.getProperty("spring.profiles.active");
		
		
	    // 服务端口
	    final String port = environment.getProperty("server.port");
		
	    // 服务访问路径
	    final String contextPath = environment.getProperty("server.servlet.context-path");

		
    }
