Java SLF4J警告-记录器将无法工作，因为它们是在初始化阶段创建的

我正在dropwizard应用程序中使用带有logback的slf4j。在应用程序初始化期间，我看到如下日志

SLF4J: The following loggers will not work because they were created
SLF4J: during the default configuration phase of the underlying logging system.
SLF4J: See also http://www.slf4j.org/codes.html#substituteLogger
SLF4J: com.vnera.healthandmetrics.VneraMetrics

public class VneraMetrics {
   private static final Logger logger = LoggerFactory.getLogger(VneraMetrics.class);
 ...
 // This method is getting called from Service.run() during the dropwizard application initialization
 public String getSomeValue() {
     // logger is not accessed from this function
     return "Some initialized value";
 }
}

public class Service extends Application<Conf> {
   public static final Logger logger = LoggerFactory.getLogger(Service.class);
   public static void main(String args[]) {
      logger.info("Some logs");
      Service service = new Service();
      service.run(dropWizardArgs);
      Utils.reloadLogger();
   }
}

我正在dropwizard应用程序中使用

logback.xml

。我的代码流如下所示

SLF4J: The following loggers will not work because they were created
SLF4J: during the default configuration phase of the underlying logging system.
SLF4J: See also http://www.slf4j.org/codes.html#substituteLogger
SLF4J: com.vnera.healthandmetrics.VneraMetrics

public class VneraMetrics {
   private static final Logger logger = LoggerFactory.getLogger(VneraMetrics.class);
 ...
 // This method is getting called from Service.run() during the dropwizard application initialization
 public String getSomeValue() {
     // logger is not accessed from this function
     return "Some initialized value";
 }
}

public class Service extends Application<Conf> {
   public static final Logger logger = LoggerFactory.getLogger(Service.class);
   public static void main(String args[]) {
      logger.info("Some logs");
      Service service = new Service();
      service.run(dropWizardArgs);
      Utils.reloadLogger();
   }
}

版本

• 回写-1.2.3
• Dropwizard-1.0.2

有人能告诉我SLF4J警告表示什么吗？我已经看到了这一页，但这没有提到我如何才能绕过这一点？尝试在

VneraMetrics

中使用记录器时，它不会打印任何内容
