Thanks!

Answer 1

application.yml:

root-something:
    my-properties:
        key1: val1
        key2: val2

Your type-safe pojo:

import java.util.Properties;
import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "root-something")
public class RootSomethingPojo {

    private Properties myProperties;

Your container configuration:

@Configuration
@EnableConfigurationProperties({ RootSomethingPojo .class })
public class MySpringConfiguration {

This will inject the key-value pairs directly into the myProperties field.
