Example 1
@Override
public void bind(Map<String, Object> configurationProperties, boolean ignoreUnknownFields,
                 boolean ignoreInvalidFields, Object configurationBean) {

    Iterable<PropertySource<?>> propertySources = asList(new MapPropertySource("internal", configurationProperties));

    // Converts ConfigurationPropertySources
    Iterable<ConfigurationPropertySource> configurationPropertySources = from(propertySources);

    // Wrap Bindable from DubboConfig instance
    Bindable bindable = Bindable.ofInstance(configurationBean);

    Binder binder = new Binder(configurationPropertySources, new PropertySourcesPlaceholdersResolver(propertySources));

    // Get BindHandler
    BindHandler bindHandler = getBindHandler(ignoreUnknownFields, ignoreInvalidFields);

    // Bind
    binder.bind("", bindable, bindHandler);
}
