slf4j日志使用

首先需求slf4j-api-1.5.8.jar和slf4j-log4j12-1.5.8.jar包

然后在src下创建log4j.properties文件，添加

#
# XXX GeeData Logging Configuration
#
log4j.rootLogger=info, stdout, R
#stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p %d{yy-MM-dd HH:mm:ss} %c:%L - %m%n
#file
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=logs/mylog.log #指定日志输出的路径
log4j.appender.R.Threshold=INFO
log4j.appender.R.MaxFileSize=100MB
log4j.appender.R.MaxBackupIndex=10
log4j.appender.R.layout=org.apache.log4j.PatternLayout
# [u673Au5668ip|u65E5u5FD7u7EA7u522B|u65F6u95F4] [u7EBFu7A0Bu540D|u7C7Bu540D|u65B9u6CD5u540D|u884Cu53F7] [u4EA7u54C1id|u7248u672Cu53F7] message
log4j.appender.R.layout.ConversionPattern=[%X{ip}|%p|%d{yyyy-MM-dd HH:mm:ss}] [%t|%C|%M|%L] [%X{productname}|%X{productversion}] - %m%n

在代码里面直接引用slf4j包，就可以用了

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class CrTemplateAction extends BaseAction implements ModelDriven<CrTemplate>{
  private static final Logger log = LoggerFactory.getLogger(CrTemplateAction.class);
      log.info("解码‘网站名称’出错。");
   

}
