带有eclipse microprofile-config的自定义配置文件

Question

I want to select .properties file at runtime. Is it possible with microprofile-config? So, instead of using META-INF/microprofile-config.properties I would like to use an external file:

java -jar mymicroprofileapp.jar -s my.properties

I know, it is possible to write custom config source, but I wonder if there is a built-in option to define the config file and so avoiding repeating the code in each project

Answer 1

The web site tells us the three options:

• System.getProperties()
• System.getenv()
• META-INF/microprofile-config.properties .

I addition to these you can register ConfigSources .

There is no build-in option for what you want.
