在log4j中配置RollingFileAppender [英] Configuring RollingFileAppender in log4j

问题描述

我正在处理一组网络服务，我们希望每天都有一个轮换日志。

I'm working on a set of web services and we'd like to have a daily rotated log.

我正试图获得 org.apache.log4j.rolling.RollingFileAppender 来自log4j extras配套工作，因为文档建议这最适合生产环境。

I'm trying to get org.apache.log4j.rolling.RollingFileAppender from the log4j extras companion working, since the documentation suggests this is best for production environments.

我有两个主log4J库（ log4j-1.2.15.jar ）和log4j额外库（ apache-log4j-extras-1.1。类路径上的jar ）。

I have both the main log4J library (log4j-1.2.15.jar) and the log4j extras library (apache-log4j-extras-1.1.jar) on the classpath.

我在 log4j.properties file：

### SOAP Request Appender
log4j.appender.request=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.request.File=SOAPmessages.log
log4j.appender.request.RollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.request.RollingPolicy.ActiveFileName =SOAPmessages-%d.log
log4j.appender.request.RollingPolicy.FileNamePattern=SOAPmessages-%d.log.zip
log4j.appender.request.layout = org.apache.log4j.PatternLayout
log4j.appender.request.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

然而，当我使用log4j启动Web服务时在调试模式下，我收到以下错误消息：

However, when I start the web service with log4j in debug mode I get these error messages:

log4j: Parsing appender named "request".
log4j: Parsing layout options for "request".
log4j: Setting property [conversionPattern] to [%d{ABSOLUTE} %5p %c{1}:%L - %m%n].
log4j: End of parsing for "request".
log4j: Setting property [file] to [/logs/SOAPmessages.log].
log4j:WARN Failed to set property [rollingPolicy] to value "org.apache.log4j.rolling.TimeBasedRollingPolicy". 
log4j:WARN Please set a rolling policy for the RollingFileAppender named 'request'
log4j: Parsed "request" options.

我找到了关于如何配置这个appender有点稀疏的文档，所以任何人都可以帮助我修复配置？

I've found documentation about how to configure this appender a little sparse, so can anyone help me fix my configuration?

EDIT0：添加了调试模式输出，而不仅仅是标准警告

Added debug mode output, rather than just the standard warnings

推荐答案

更新：至少早在2013年（参见Mubashar的评论）开始工作。

Update: at least as early as 2013 (see Mubashar's comment) this started working.

根据 Log4jXmlFormat ，你不能使用log4j.properties配置它，但只使用XML配置格式：

According to Log4jXmlFormat you cannot configure it with log4j.properties, but only using the XML config format:

请注意，TimeBasedRollingPolicy只能配置xml，而不能配置log4j。属性

Note that TimeBasedRollingPolicy can only be configured with xml, not log4j.properties

不幸的是，它们提供的示例log4j.xml也不起作用：

Unfortunately, the example log4j.xml they provide doesn't work either:

log4j:ERROR Parsing error on line 14 and column 76
log4j:ERROR Element type "rollingPolicy" must be declared.
...
log4j:WARN Please set a rolling policy for the RollingFileAppender named 'FILE'
