spring boot load the property files by four ways

URL Original Answer

By default ,SpringApplication loads properties from application.properties files in the following locations and adds them to the Spring Environment:

1. A /config subdirectory of the current directory
2. The current directory
3. A classpath /config package
4. The classpath root

As same as

1. file:./config/
2. file:./
3. classpath:/config/
4. classpath:/

The list is ordered by precedence

classpath:/config/ and classpath:/ it`s ok , but when i put file in file:./config/ or file:./ . there are some problem happends

IDEA

When application.properties locate in resources or /resourece/config , it works

But if i put the application.properties in the subdirectory of the current directory or ./config it can not work

i do it just like doc says ,but it failed . so google ~~

the location file:./config/ and file:./ not means your idea folder it means below

when you use maven to package the project you can get a XXX.jar in targer
