I'm trying to bind generator.yaml file with an object of type GeneratorConfig using Spring Boot 2.0.5.RELEASE:
generator.yaml:
entry:
name: "node-1"
expectedState: HEALTHY
@Component
@PropertySource("classpath:generator.yaml")
@ConfigurationProperties
public class GeneratorConfig {
private Entry entry;
// getter and setter
}
public class Entry {
private String name;
private NodeState expectedState;
// getters and setters
}
And I'm getting the following exception:
