Sample 5 – AsyncAppender with Console and File

使用AsyncAppender的Log4j 1.x XML配置。

1. 1. <?xml version=“1.0” encoding=“UTF-8”?>
   2. <!DOCTYPE log4j:configuration PUBLIC “-//APACHE//DTD LOG4J 1.2//EN” “log4j.dtd”>
   3. <log4j:configuration xmlns:log4j=“http://jakarta.apache.org/log4j/” configDebug=“true”>
   4. <appender
      name=“ASYNC” class=“org.apache.log4j.AsyncAppender”>
   5. <appender-ref ref=“TEMP”/>
   6. <appender-ref ref=“CONSOLE”/>
   7. </appender>
   8. <appender name=“CONSOLE” class=“org.apache.log4j.ConsoleAppender”>
   9. <layout class=“org.apache.log4j.PatternLayout”>
   10. <param name=“ConversionPattern”
       value=“%d %-5p [%t] %C{2} (%F:%L) – %m%n”/>
   11. </layout>
   12. </appender>
   13. <appender name=“TEMP” class=“org.apache.log4j.FileAppender”>
   14. <param name=“File” value=“temp”/>
   15. <layout class=“org.apache.log4j.PatternLayout”>
   16. <param name=“ConversionPattern” value=“%d %-5p [%t] %C{2} (%F:%L) – %m%n”
       />
   17. </layout>
   18. </appender>
   19. <root>
   20. <priority value=“debug”/>
   21. <appender-ref ref=“ASYNC”/>
   22. </Root>
   23. </log4j:configuration>

Log4j 2 XML配置。需要注意的是，Async Appender需要在Appender引用的後面配置，這樣才能讓它正確的關閉。

1. 1. <?xml version=“1.0” encoding=“UTF-8”?>
   2. <Configuration status=“debug”>
   3. <Appenders>
   4. <Console name=“CONSOLE” target=“SYSTEM_OUT”>
   5. <PatternLayout pattern=“%d %-5p [%t] %C{2} (%F:%L) – %m%n”/>
   6. </Console>
   7. <File name=“TEMP” fileName=“temp”>
   8. <PatternLayout pattern=“%d %-5p [%t] %C{2} (%F:%L) – %m%n”/>
   9. </File>
   10. <Async name=“ASYNC”>
   11. <AppenderRef ref=“TEMP”/>
   12. <AppenderRef ref=“CONSOLE”/>
   13. </Async>
   14. </Appenders>
   15. <Loggers>
   16. <Root level=“debug”>
   17. <AppenderRef ref=“ASYNC”/>
   18. </Root>
   19. </Loggers>
   20. </Configuration>
