How to parse part of a YAML file in SnakeYaml

Question

I am new to YAML and have parse a YAML config file that looks like:

applications:
  authentication:
    service-version: 2.0
    service-url: https://myapp.corp/         


        

Answer 1

So as you have the same properties in the Auth and Service configuration I simplified that in one class to show you here.

The YamlConfig class look like this:

public class YamlConfig {

  private Map applications;

  //... getter and setters here
}

And the the Parser logic is something like that :

Yaml yaml = new Yaml(new Constructor(YamlConfig.class));
InputStream input = new FileInputStream(new File("/tmp/apps.yml"));
YamlConfig data = yaml.loadAs( input, YamlConfig.class);
