HOCON Config Source#
This Config Source allows to use the HOCON file format to
load configuration values. The HOCON Config Source loads the
configuration from the file META-INF/microprofile-config.conf
. It has a lower ordinal (50
) than the
microprofile-config.properties
.
The following dependency is required in the classpath to use the HOCON Config Source:
<dependency>
<groupId>io.smallrye.config</groupId>
<artifactId>smallrye-config-source-hocon</artifactId>
<version>3.9.1-SNAPSHOT</version>
</dependency>
Expressions defined as ${value}
(unquoted) are resolved internally by the HOCON Config Source as described in the
HOCON Substitutions documentation. Quoted
Expressions defined as "${value}"
are resolved by SmallRye Config Property Expressions.
Consider:
hocon.conf
application.properties
The value of hocon
is bar
and the value of config
is baz
(if the properties source has a higher ordinal).
