问题描述
我有以下 XML 配置，我想转换为 java 属性文件.
I have following XML configration i would like to convert to java property file.
我收到以下错误
log4j:WARN Failed to set property [filter] to value "org.apache.log4j.varia.DenyAllFilter".
log4j:ERROR Could not instantiate class [true].

我的 XML 配置
<filter class="org.apache.log4j.varia.StringMatchFilter">
<param name="StringToMatch" value="FileNotfound" />
<param name="AcceptOnMatch" value="true" />
</filter>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMin" value="ERROR"/>
<param name="LevelMax" value="FATAL"/>
</filter>
<filter class="org.apache.log4j.varia.DenyAllFilter"/>
转换后的属性文件如下.使用 XML 配置它工作正常.
After converting the property file is as below. With XML configration it is working fine.
属性文件
log4j.rootLogger=INFO, MAIL
log4j.appender.MAIL=org.apache.log4j.net.SMTPAppender
# here's where I specify the layout and the pattern
log4j.appender.MAIL.BufferSize=1
log4j.appender.MAIL.SMTPHost=xxx.example.com
log4j.appender.MAIL.From=xxx@example.com
log4j.appender.MAIL.To=xxx@example.com
log4j.appender.MAIL.Subject=Test Email.
log4j.appender.MAIL.threshold=error
log4j.appender.MAIL.layout=org.apache.log4j.PatternLayout
log4j.appender.MAIL.layout.ConversionPattern=[%d{ISO8601}]%n%n%-5p%n%n%c%n%n%m%n%n
log4j.appender.MAIL.filter=org.apache.log4j.varia.StringMatchFilter
log4j.appender.MAIL.filter.StringToMatch=Filenotfound
log4j.appender.MAIL.filter.AcceptOnMatch=true
log4j.appender.MAIL.filter=org.apache.log4j.varia.DenyAllFilter
log4j.logger.com.devdaily.myapp=DEBUG
log4j.logger.org.springframework=DEBUG
请让我知道如何在属性文件中使用 StringToMatch 并指定
Please let me know how i can use StringToMatch in property file and specify
推荐答案
属性文件不支持过滤器.您必须切换到 XML 配置.
Properties files don't support filters. You'll have to switch to an XML configuration.
来自过滤器的文档:
请注意，过滤仅支持 DOMConfigurator.PropertyConfigurator 不支持过滤器.
Note that filtering is only supported by the
DOMConfigurator. ThePropertyConfiguratordoes not support filters.
