springboot是否可以指定application.yml檔案的路徑來進行加載,不放在resource下面

24.3 Application property files
SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:
A /config subdirectory of the current directory.
The current directory
A classpath /config package
The classpath root
The list is ordered by precedence (properties defined in locations higher in the list override those defined in lower locations).
You can also use YAML ('.yml') files as an alternative to '.properties'.
If you don’t like application.properties as the configuration file name you can switch to another by specifying a spring.config.name environment property. You can also refer to an explicit location using the spring.config.location environment property (comma-separated list of directory locations, or file paths).
$ java -jar myproject.jar --spring.config.name=myproject
or
$ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
spring.config.name and spring.config.location are used very early to determine which files have to be loaded so they have to be defined as an environment property (typically OS env, system property or command line argument).
If spring.config.location contains directories (as opposed to files) they should end in / (and will be appended with the names generated from spring.config.name before being loaded, including profile-specific file names). Files specified in spring.config.location are used as-is, with no support for profile-specific variants, and will be overridden by any profile-specific properties.
Config locations are searched in reverse order. By default, the configured locations are classpath:/,classpath:/config/,file:./,file:./config/. The resulting search order is:
file:./config/
file:./
classpath:/config/
classpath:/
When custom config locations are configured, they are used in addition to the default locations. Custom locations are searched before the default locations. For example, if custom locations classpath:/custom-config/,file:./custom-config/ are configured, the search order becomes:
file:./custom-config/
classpath:custom-config/
file:./config/
file:./
classpath:/config/
classpath:/
This search ordering allows you to specify default values in one configuration file and then selectively override those values in another. You can provide default values for you application in application.properties (or whatever other basename you choose with spring.config.name) in one of the default locations. These default values can then be overriden at runtime with a different file located in one of the custom locations.
If you use environment variables rather than system properties, most operating systems disallow period-separated key names, but you can use underscores instead (e.g. SPRING_CONFIG_NAME instead of spring.config.name).
If you are running in a container then JNDI properties (in java:comp/env) or servlet context initialization parameters can be used instead of, or as well as, environment variables or system properties.

在application.yml里面指定你要參考的yml的位置spring:
config:
location: ../yml-test/application.yml
也可以使用絕對路徑
