1.多个环境的配置文件

在application.yml 中配置需要调用的配置文件

spring:

  profiles:

运行方式的，先运行application.yml 再根据active指定的配置文件，进行覆盖。

linux中启动程序指定配置文件

java -jar springbootdemo.jar -- spring.profiles.active=dev

2.运行状态监控Actuator

pom中引入依赖

<!--运行状态监控-->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-actuator</artifactId>

        </dependency>

在application.yml文件中配置
