springboot加载配制文件_写给自己看

Spring Boot默认的配置文件名称为application.properties
寻找顺序如下:
a.当前目录下的/config子目录
b.当前目录
c.一个classpath下的/config包
d.classpath根路径（root）

列如
 application.properties内容如下
ftm.redis.addressList=10.17.5.24:6379,10.17.5.24:6380
ftm.redis.minIdle=10
ftm.redis.maxIdle=100
ftm.redis.maxTotal=8
ftm.redis.maxWaitMillis=1000
-------------------------------------------------------------------------
对应的java类应该有这两个注解
@Component
@ConfigurationProperties(prefix = "ftm.redis")
