SpringBoot 配置文件(yml)

可以配置参数替换默认值
SpringBoot默认会从Resources目录下加载application.properties或application.yml（application.yaml）文件

spring-boot-starter-parent中有这么一段

<resource>
  <directory>${basedir}/src/main/resources</directory>
  <filtering>true</filtering>
  <includes>
    <include>**/application*.yml</include>
    <include>**/application*.yaml</include>
    <include>**/application*.properties</include>
  </includes>
</resource>

意思就是先读yml 再读yaml,再读properties,后者会覆盖前者

详细的配置信息可以在
