我想使用我的记录器写入两个不同的文件,声明如下:
public static final Logger logger = Logger.getLogger(Adapt.class);
PropertyConfigurator.configure("log4j.properties");
文件log4j包含:
log4j.rootLogger=DEBUG, FA
#File Appender
log4j.appender.FA=org.apache.log4j.FileAppender
log4j.appender.FA.File=temp.ppr
log4j.appender.FA.layout=org.apache.log4j.PatternLayout
log4j.appender.FA.append=false
log4j.appender.FA.layout.ConversionPattern= %m%n
是否可以使用记录器轻松地将不同的文本写入两个不同的文件?
如果没有,有没有办法用两个记录器做到这一点? (我试过并因为函数configure而出现问题,这是静态的。)
感谢。

只需定义第二个记录器变量:
Logger otherLogger = Logger.getLogger("OTHER_LOGGER");
为其定义配置(请注意log4j。 logger .OTHER_LOGGER语法cf. log4j.rootLogger,如user623395和venkatesh Dodla所指出的那样):
log4j.logger.OTHER_LOGGER=DEBUG, OtherAppender
log4j.additivity.OTHER_LOGGER = false
#File Appender
log4j.appender.OtherAppender=org.apache.log4j.FileAppender
log4j.appender.OtherAppender.File=temp2.ppr
log4j.appender.OtherAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.OtherAppender.append=false
log4j.appender.OtherAppender.layout.ConversionPattern= %m%n
并照常记录您的不同文字:
logger.debug("My normal log");
otherLogger.info("My special text");

要创建temp2.ppr,请从
更改log4j.OTHER_LOGGER=DEBUG, OtherAppender
到
log4j.**logger**.OTHER_LOGGER=DEBUG, OtherAppender

# log4j.properties
log4j.rootLogger=DEBUG,hfis,stdout
#For second log
log4j.logger.OTHER_LOGGER=DEBUG, OtherAppender
log4j.additivity.OTHER_LOGGER = false
#File Appender
log4j.appender.OtherAppender=org.apache.log4j.FileAppender
log4j.appender.OtherAppender.File=C:\\Legacy.log
log4j.appender.OtherAppender.ImmediateFlush=true
log4j.appender.OtherAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.OtherAppender.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss.SSS} [%t] %-5p %c - %m%n
log4j.rootCategory=ERROR
log4j.rootLogger.additivity=false
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.hfis=org.apache.log4j.RollingFileAppender
log4j.appender.hfis.Threshold=DEBUG
log4j.appender.hfis.file=C:\\hfis.log
log4j.appender.hfis.ImmediateFlush=true
log4j.appender.hfis.MaxFileSize=5MB
log4j.appender.hfis.layout=org.apache.log4j.PatternLayout
log4j.appender.hfis.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss.SSS} [%t] %-5p %c - %m%n
# R is the RollingFileAppender that outputs to a rolling log
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold=DEBUG
# Define a pattern layout for the file.
log4j.appender.mystdout.layout=org.apache.log4j.PatternLayout
log4j.appender.mystdout.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss.SSS} %-5p: %m%n<br>
我的日志变量是
final static Logger log = Logger.getLogger("hfis");
final static Logger log2 = Logger.getLogger("OTHER_LOGGER");
