Java Spring属性与Proguard的绑定

我使用Proguard混淆了下面的Spring配置类。我在下面给出了我使用的Proguard选项。该类应绑定到属性文件中名为

http.cache.timeToLiveInDays

的属性

@ConfigurationProperties(prefix = "onboarding", ignoreUnknownFields = false)
public class OnboardingProperties {
    private final Http http = new Http();

    public Http getHttp() {
        return http;
    }

    public static class Http {
        private final Cache cache = new Cache();

        public Cache getCache() {
            return cache;
        }

        public static class Cache {
            private int timeToLiveInDays = 1461;

            public int getTimeToLiveInDays() {
                return timeToLiveInDays;
            }
            public void setTimeToLiveInDays(final int timeToLiveInDays) {
                this.timeToLiveInDays = timeToLiveInDays;
            }
        }
    }
}

属性文件

application.yml

包含以下内容：

onboarding:
    http:
        cache:
            timeToLiveInDays: 1234

有什么办法可以解决这个问题吗？

我设法用

-keep public class com.test.blah.config.OnboardingProperties {
  private <fields>;
  *** get*();
}
-keep class com.test.blah.config.OnboardingProperties$* {
  private <fields>;
  void set*(***);
  *** get*();
}

-keep public class com.test.blah.config.OnboardingProperties {
  private <fields>;
  *** get*();
}
-keep class com.test.blah.config.OnboardingProperties$* {
  private <fields>;
  void set*(***);
  *** get*();
}

-keep public class com.test.blah.config.OnboardingProperties
-keep public class com.test.blah.config.OnboardingProperties$* {
  *;
}
