I try to use String with json like this

{"group1": {"group11": {"name": "element1", "link": "<LINK>"}, "group12": {"name": "element2", "link": "<LINK>"}},"group2": {"group21": {"name": "element3","link": "<LINK>"}}}

as configuration in my Spring application.

I added configuration like this in my application.yaml file:

my-config:
  string-with-json: ${STRING_JSON}
  other-option: string

and wrote property class:

@Data
@Configuration
@ConfigurationProperties("my-config")
public class BaseImagesProperties {

    public Map<String, Map<String, Map<String, String>>> stringWithJson;
    public String otherOption;

    public String getLink(String group, String element) {
        return stringWithJson.get(group).get(element).get("link");   
    }
}

When I started my app, it swears that he can’t convert a string to Map<String, Map<String, Map<String, String>>>

How can I properly convert it to this?
