# 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
    log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
