log4j配置问题

[a_]

log4j.logger.helloappLogger=WARN,console,file

log4j.appender.console=org.apache.log4j.ConsoleAppender

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=E:/test/lo/helloapp/WEB-INF/log.txt


log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %l "--" %m%n
log4j.appender.file.DatePattern='.'yyyy-MM-dd
我想每天产生一个日志，这种配置需要改哪里呀？

log4j.rootLogger=DEBUG, A1,A2
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A2.file=C:\\Test
log4j.appender.A2.DatePattern='.'yyyy-MM-dd'.log'
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%d [%t][%-5p] %c{2} - %m%n
