Is it possible to read YAML property into Map using Spring and @Value annotation

What I want to be able to do is:

YAML:

features:
    feature1: true
    feature2: false
    feature3: true

Code:

@Value("${features}")
private Map<String,Boolean> features;

I can't figure out what Spring scripting syntax to use to do this (if it's possible at all)

I'm using Spring Boot and access custom variables like this:

  1. Create a custom class that maps to your custom properties:

    @Component
@ConfigurationProperties(prefix="features")
public class ConstantProperties {
    private String feature1;

    public String getFeature1(){
        return feature1;
    }
    public void setFeature1(String feature1) {
        this.feature1 = feature1;
    }
}

  2. YAML file will look like this:

    features:
  feature1: true
  feature2: false
  feature3: true

  3. in your class that you want to access these properties, you can use the following:

    @Autowire 
private ConfigurationProperties configurationProperties;

  4. Then to access in that class, use the following syntax:

    configurationProperties.getFeature1();

  5. Or you can reference the custom property like:

    "{{features.feature1}}"
