Package io.smallrye.config.source.file

Class FileSystemConfigSource

java.lang.Object

io.smallrye.config.common.AbstractConfigSource

io.smallrye.config.common.MapBackedConfigSource

io.smallrye.config.source.file.FileSystemConfigSource

All Implemented Interfaces:

Serializable, org.eclipse.microprofile.config.spi.ConfigSource

public class FileSystemConfigSource
extends io.smallrye.config.common.MapBackedConfigSource

Read configuration from a file directory.

Each file in the directory corresponds to a property where the file name is the property key and the file textual content is the property value.

For example, if a directory structure looks like:

 
 foo/
 ├── num.max
 └── num.size
 
 

new FileSystemConfigSource(new File("foo"), 100) will provide 2 properties:

• num.max
• num.size

Nested directories are not supported.
