MicroProfile 的配置：如何注入自定义 object 列表

Question

i'm trying to inject a list of object in quarkus but I receive an error "No Converter registered for class ExternalApiParam".

My yaml is:

custom:
  external-api-list:
    - name: example-1
      uri: https://run.mocky.io/v3/55402172-82c3
    - name: example-2
      uri: https://run.mocky.io/v3/13417375-a19c

My config class is:

@ConfigProperties(prefix = "custom")
@Data
public class ExternalApiConfigProperties {

    List<ExternalApiParam> externalApiList;
}

What do I wrong?

Answer 1

You need to provide a Config Converter class that can read the configuration value and convert it to your object.

Please check here for an example: https://github.com/smallrye/smallrye-config/blob/master/sources/yaml/src/test/java/io/smallrye/config/source/yaml/YamlConfigSourceTest.java#L141-L153
