SpringBoot中logback日志保存到mongoDB的方法

public class MongoDBAppender extends 
    UnsynchronizedAppenderBase<ILoggingEvent> { 
 
  @Override 
  protected void append(ILoggingEvent eventObject) { 
    MongoTemplate mongoTemplate = ApplicationContextProvider.getBean(MongoTemplate.class); 
    if (mongoTemplate != null) { 
      final BasicDBObject doc = new BasicDBObject(); 
      doc.append("level", eventObject.getLevel().toString()); 
      doc.append("logger", eventObject.getLoggerName()); 
      doc.append("thread", eventObject.getThreadName()); 
      doc.append("message", eventObject.getFormattedMessage()); 
      mongoTemplate.insert(doc, "log"); 
    } 
  } 
 
} 

@Component 
public class ApplicationContextProvider implements ApplicationContextAware { 
  private static ApplicationContext context; 
 
  public static ApplicationContext getApplicationContext() { 
    return context;

  @Override
