Java Web サービスで、log4j を使用して Windows イベント ビューアにログを書き込もうとしています。Tomcat を使用してデプロイするための IDE として Eclipse を使用しています。
これは私のlog4j.propertiesです:
log4j.rootLogger=DEBUG, CA, NTEventLog
log4j.rootLogger=DEBUG, CA, NTEventLog
#Console Appender
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
#File Appender
log4j.appender.FA=org.apache.log4j.FileAppender
log4j.appender.FA.File=sample.log
log4j.appender.FA.layout=org.apache.log4j.PatternLayout
log4j.appender.FA.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
#Event Log Appender
log4j.appender.NTEventLog=org.apache.log4j.nt.NTEventLogAppender
log4j.appender.NTEventLog.source=ESB Web Services
# Set the logger level of File Appender to WARN
log4j.appender.FA.Threshold = WARN
これは私のクラスパスです:
