static   保存所有的静态资源 css js images
templates 保存所有的模板页面 （Spring Boot默认jar包使用嵌入式的Tomcat，默认不支持JSP页
           面）；可以使用模板引擎（freemarker、thymeleaf）；
application.properties 修改默认的Spring Boot应用的配置文件 application.yml

# 端口号配置，大小值属性敏感 以 key：value 键值对存在
server:
   port: 8080  #左对齐控制层级关系
   path: /1234

对象：
friends：
   name: niund
   ange: 1234
#行内写法： friend: { name: haha ,age: 123}

数组 list set
arrays：
   - index1
   - index2
   - index3
   #行内写法：arrays：[index1,index0,index2,index3]

 springboot 启动会扫描以下位置的application.properties或者application.yml文件作为Spring boot的默认配置文
 件
 –file:./config/
 –file:./
 –classpath:/config/
 –classpath:/
 优先级由高到底，高优先级的配置会覆盖低优先级的配置；

SpringBoot会从这四个位置全部加载主配置文件；互补配置；
我们还可以通过spring.config.location来改变默认的配置文件位置
项目打包好以后，我们可以使用命令行参数的形式，启动项目的时候来指定配置文件的新位置；指定配置文件和默
认加载的这些配置文件共同起作用形成互补配置；
java -jar spring-boot-02-config-02-0.0.1-SNAPSHOT.jar --spring.config.location=G:/application.properties


debug=true //控制台打印自动配置报告可以很方便的知道哪些自动配置
