Question

我正在使用app.yaml查看GAE托管虚拟机，如此处所述https://cloud.google.com/appengine/docs/managed-vms/java/configuring-your-app-with-app-yaml

当我这样做时

env_variables:
  java.util.logging.config.file: 'WEB-INF/logging.properties'

我得到例外

google.appengine.api.yaml_errors.EventError: Value 'java.util.logging.config.file' for key in EnvironmentVariables does not match expression '^(?:[a-zA-Z_][a-zA-Z0-9_]*)$'

有没有办法通过app.yaml指定自定义logging.properties？

Answer 1

试试这个：

env_variables:
  JAVA_USER_OPTS: -Djava.util.logging.config.file=webapps/root/WEB-INF/logging.properties

env_variables中的app.yaml部分用于设置环境变量。 not allowed，因此异常是有道理的。

您正在尝试设置java.util.logging.config.file，这是一个系统属性，而不是环境变量。要设置它，您需要在启动Java时提供-Djava.util.logging.config.file=<value>参数。 GAE Flexible image提供JAVA_USER_OPTS环境变量来自定义Java命令行，因此您可以使用它来自定义JUL设置（现在也建议在图像readme中使用）。

此外，WEB-INF/logging.properties值对我不起作用，因为当前目录为$JETTY_BASE，而不是$JETTY_BASE/webapps/root。

Answer 2

另一个答案不再正确。属性名称现在名为JAVA_OPTS

这里有完整的'秘密'变量名称 https://github.com/GoogleCloudPlatform/jetty-runtime#providing-loggingproperties-via-the-web-application

现在这是正确的设置：

对于通用弹性环境，请使用此格式。

env_variables:
  JETTY_ARGS: -Djava.util.logging.config.file=WEB-INF/logging.properties
