log4j StringToMatch in property file

Question

I have following XML configration i would like to convert to java property file.

I am getting below error

log4j:WARN Failed to set property [filter]         


        

Answer 1

Properties files don't support filters. You'll have to switch to an XML configuration.

From the documentation of Filter :

Note that filtering is only supported by the DOMConfigurator. The PropertyConfigurator does not support filters.

Answer 2

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d %-6p [%c] %m%n
log4j.appender.console.filter.1=org.apache.log4j.varia.StringMatchFilter
log4j.appender.console.filter.1.StringToMatch=entered
log4j.appender.console.filter.1.AcceptOnMatch=true
log4j.appender.console.filter.2=org.apache.log4j.varia.DenyAllFilter

does work
