JSON Converter#

The JSON Converter allows to convert a configuration value into a JsonObject or JsonArray.

The following dependency is required in the classpath to use the JSON Converter:

<dependency>
    <groupId>io.smallrye.config</groupId>
    <artifactId>smallrye-config-converter-json</artifactId>
    <version>3.5.4</version>
</dependency>

JsonObject or JsonArray are automatically converted from their String value.

@Inject
@ConfigProperty(name = "someJsonArray")
private JsonArray someValue;

@Inject
@ConfigProperty(name = "someJsonObject")
private JsonObject someValue;

someJsonArray=["value1","value2","value3"]
someJsonObject={"foo": "bar", "count":100}

The value of the configuration properties must be valid JSON, or a JsonParsingException is thrown.
