saas-export项目spring整合springmvc

spring整合springmvc

• （1）log4j.properties
• （2）web.xml
• （3）springmvc.xml

log4j.properties

不在别的子工程中添加呢？当前 web层的数据的接收与返回，非常重要

log4j.rootLogger=debug, stdout, logfile

log4j.category.org.springframework=info
#log4j.category.org.apache=INFO

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=c:\\log\\myweb.log
log4j.appender.logfile.MaxFileSize=1KB
log4j.appender.logfile.MaxBackupIndex=5
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
