java - 为什么 dropwizard 无法配置我的记录器？

Question

我只是尝试将日志配置添加到 dropwizard 的 yaml 配置文件中。我正在运行 dropwizard 版本 0.9.2，我的 yaml 包含以下内容:

logging:
  level: INFO
  appenders:
    - type: file
      currentLogFilename: ./log/mylogfile.log
      threshold: ALL
      archive: true
      archivedLogFilenamePattern: ./log/mylogfile-%d{yyyy-MM-dd-HH}.log
      archivedFileCount: 5
      timeZone: UTC
      logFormat: # TODO

我的 fatjar 肯定有

META-INF/services/io.dropwizard.logging.AppenderFactory

其中包含

io.dropwizard.logging.ConsoleAppenderFactory
io.dropwizard.logging.FileAppenderFactory
io.dropwizard.logging.SyslogAppenderFactory

但我在启动时得到这个...

9:29:28 AM web.1 |    * Failed to parse configuration at: logging.appenders.[0]; Could not resolve type id 'file' into a subtype of [simple type, class io.dropwizard.logging.AppenderFactory]: known type ids = [AppenderFactory]
9:29:28 AM web.1 |   at [Source: N/A; line: -1, column: -1] (through reference chain: com.salesforce.analytics.query.AppConfiguration["logging"]->io.dropwizard.logging.DefaultLoggingFactory["appenders"]->java.util.ArrayList[0])

关于我做错了什么有什么帮助吗？

请检查您的 yml 文件中是否使用制表符，而不是使用双空格，我正在使用以下日志配置及其工作正常，还要验证您的 pom 文件，您需要包含 Maven Shade 插件，还添加了我的 pom 文件的构建部分

logging:
  # The default level of all loggers. Can be OFF, ERROR, WARN, INFO, DEBUG, TRACE, or ALL.
  level: INFO
  loggers:
    "org.skife.jdbi.v2": TRACE
  appenders:
    - type: file
      # The file to which current statements will be logged.
      currentLogFilename: ./logs/mylogfile.log

      # When the log file rotates, the archived log will be renamed to this and gzipped. The
      # %d is replaced with the previous day (yyyy-MM-dd). Custom rolling windows can be created
      # by passing a SimpleDateFormat-compatible format as an argument: "%d{yyyy-MM-dd-hh}".
      archivedLogFilenamePattern: ./logs/mylogfile-%d.log.gz

      # The number of archived files to keep.
      archivedFileCount: 5

      # The timezone used to format dates. HINT: USE THE DEFAULT, UTC.
      timeZone: UTC
