我有一个在 Google App Engine (GAE) v1.8.2 上运行的应用程序。我一直在使用 java.util.logging。我的课程将记录器定义为：

private static final Logger logger = Logger.getLogger(MyClass.class.getName());

我的 appengine-web.xml 有以下几行：

  <!-- Configure java.util.logging -->
  <system-properties>
    <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
  </system-properties>

logging.properties 文件包含以下几行：

# A default java.util.logging configuration.
# (All App Engine logging is through java.util.logging by default).
#
# To use this configuration, copy it into your application's WEB-INF
# folder and add the following to your appengine-web.xml:
# 
# <system-properties>
#   <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
# </system-properties>
# WARNING , INFO, SEVERE, OFF
handlers=java.util.logging.ConsoleHandler
# Set the default logging level for all loggers to WARNING
.level = OFF
java.util.logging.ConsoleHandler.level=OFF
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

但是，我仍然在浏览器控制台中继续看到来自我的代码的 INFO 日志记录。如何完全关闭控制台注销？

更新：我的 appengine-java-sdk-1.8.2/config/sdk/logging.properties 文件的内容：

# Logging configuration file for Google App Engine tools.

# Specify the handlers to create in the root logger
# (all loggers are children of the root logger)
# The following creates the console handler
handlers = java.util.logging.ConsoleHandler

# Set the default logging level for the root logger
.level = INFO

# Set the default logging level for the datanucleus loggers
DataNucleus.JDO.level=WARNING
DataNucleus.Persistence.level=WARNING
DataNucleus.Cache.level=WARNING
DataNucleus.MetaData.level=WARNING
DataNucleus.General.level=WARNING
DataNucleus.Utility.level=WARNING
DataNucleus.Transaction.level=WARNING
DataNucleus.Datastore.level=WARNING
DataNucleus.ClassLoading.level=WARNING
DataNucleus.Plugin.level=WARNING
DataNucleus.ValueGeneration.level=WARNING
DataNucleus.Enhancer.level=WARNING
DataNucleus.SchemaTool.level=WARNING

# FinalizableReferenceQueue tries to spin up a thread and fails.  This
# is inconsequential, so don't scare the user.
com.google.common.base.FinalizableReferenceQueue.level=WARNING
com.google.appengine.repackaged.com.google.common.base.FinalizableReferenceQueue.level=WARNING

# We assume that people will generally want to see this message, even
# if they override the root level to WARNING.  If they really want to
# turn it off, they can always override this level as well.
com.google.appengine.tools.development.DevAppServerImpl.level=INFO

谢谢。

您应该确认LogManager正在使用您的logging.properties. 一种简单的测试方法是将ConsoleHandler格式化程序从更改java.util.logging.SimpleFormatter为java.util.logging.XMLFormatter然后查看您的输出是否为 xml。如果是 xml，那么您可以尝试注释掉该handlers=行。如果输出仍然来自SimpleFormatterthen：

  1. 检查 logging.properties 的路径。
  2. 确保 aSecurityManager不会阻止对日志记录的更改。
  3. 编写代码来遍历所有记录器并输出所有附加处理程序的类名。然后更新您logging.properties以禁用可能正在写入控制台的任何其他处理程序。
  4. 编写代码来遍历所有记录器并禁用所有控制台处理程序。
  5. System.out.close(); System.err.close();
  6. 新的 FileOutputStream(FileDescriptor.out).close(); 新的 FileOutputStream(FileDescriptor.err).close();
