SpringBoot获取运行环境 获取静态配置 SpringBoot获取配置文件和属性值 springboot获取配置文件

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))
