以下のようなスプリングレストコントローラのカスタムオブジェクトのリストを読み取ることができません。しかし、restowollerのJava BeanにBeanをautowiringしてデータを読み込み/取得することができます。 annonation @valueを使って、残りのコントローラからのデータのリストを読んで助けてもらえますか？プレースホルダを解決できませんでした。文字列値のカスタムオブジェクトのリスト
文字列値 "$ {royalty.testRates}"のプレースホルダのカスタムオブジェクト（royalty.testRates）のリストを解決できませんでした。 YAMLファイルの
コードスニペット： Java Beanが：
@EnableAsync
@Configuration
@EnableConfigurationProperties
@ConfigurationProperties(ignoreInvalidFields = false, prefix = "royalty")
@Component
public class RoyaltyMigration {
private List<TestRate> testRates = new ArrayList<TestRate>();
public static class TestRate {
private String channelType;
private String value;
public List<TestRate> getTestRates() {
return testRates;
}
public void setTestRates(List<TestRate> testRates) {
this.testRates = testRates;
}
public String getChannelType() {
return channelType;
}
public void setChannelType(String channelType) {
this.channelType = channelType;
