本文介绍了如何配置slf4j与log4j，以便在出现error级别日志时发送邮件。关键配置包括设置log4j.appender.logMail.SMTPProtocol为smtps以及提供SMTPPassword。不正确配置会导致错误，作者新开设的博客欢迎大家访问。

代码使用slf4j的接口，具体日志实现框架用log4j标准输出日志格式


#用Email发送日志
log4j.appender.logMail = org.apache.log4j.net.SMTPAppender
log4j.appender.logMail.layout = org.apache.log4j.HTMLLayout
log4j.appender.logMail.layout.LocationInfo = TRUE
log4j.appender.logMail.layout.Title = Log4j LogFile Mail
log4j.appender.logMail.Threshold = ERROR
log4j.appender.logMail.SMTPDebug = TRUE
log4j.appender.logMail.SMTPProtocol = smtps
log4j.appender.logMail.SMTPHost = SMTP.qq.com
log4j.appender.logMail.From = xx@qq.com
log4j.appender.logMail.To = yy@qq.com,zz@163.com
#抄送
log4j.appender.logMail.Cc = zz@163.com
#密送
#og4j.appender.logMail.Bcc = zz@163.com
log4j.appender.logMail.SMTPUsername = xx@qq.com
log4j.appender.logMail.SMTPPort= 465
log4j.appender.logMail.SMTPPassword = ***
#主题
log4j.appender.logMail.Subject = Log4j Log Messages
#log4j.appender.logMail.BufferSize = 1024
#log4j.appender.logMail.SMTPAuth = TRUE

重要的两个配置

log4j.appender.logMail.SMTPProtocol = smtps

log4j.appender.logMail.SMTPPassword = *，其中password为授权码

附上官网解释：

这里写图片描述

否则会报如下错误：

DEBUG SMTP: trying to connect to host "SMTP.qq.com", port 465, isSSL false
log4j:ERROR Error occured while sending e-mail notification.
