发送错误日志到邮箱的两种方式

最近写项目考虑把一些运行时候出现的异常发送邮箱，这样可以随时监控错误，网上看可以用log4j发送错误日志到邮箱，现在把这种方式记录下来，以备下次用

1.log4j方式

需要jar包

javax.mailmail1.4.7

org.slf4jslf4j-log4j12${slf4j.version}log4j.properties配置这里需要配置上mail

log4j.rootlogger=mail

#发送错误邮件log4j.appender.mail=org.apache.log4j.net.smtpappenderlog4j.appender.mail.threshold=errorlog4j.appender.mail.buffersize=10log4j.appender.mail.from=*****@126.comlog4j.appender.mail.smtphost=smtp.126.comlog4j.appender.mail.smtpusername=*****log4j.appender.mail.smtppassword=*******log4j.appender.mail.smtpdebug=truelog4j.appender.mail.subject=log4jerrormessagelog4j.appender.mail.to=*****@163.comlog4j.appender.mail.layout=org.apache.log4j.patternlayoutlog4j.appender.mail.layout.conversionpattern=[framework]%d-%c-%-4r[%t]%-5p%c%x-%m%n我用126邮箱发送给163邮箱，打码的依次是发送邮箱名，邮箱名，密码，接收邮箱名，smtpuhost根据每个邮箱不同，需要自己修改，发送邮件的日志级别是error型。

自己测试，每次会发送三次邮件，一次是自己做aop异常捕获的，还有两次是druid打印的错误日志，有点繁琐。决定用第二种方式。

2.自定义邮件发送util

这个还是需要上面的mail包，下面是我自定义的异常邮件发送工具

importorg.springframework.mail.mailexception;importorg.springframework.mail.javamail.javamailsenderimpl;importorg.springframework.mail.javamail.mimemessagehelper;importjavax.mail.messagingexception;importjavax.mail.internet.mimemessage;importjava.io.unsupportedencodingexception;importjava.util.properties;/***description**@authorwangsong*@date19:392018/1/30*/publicclasserrorlogmail{privatestaticfinalstringhost="smtp.126.com";privatestaticfinalintegerport=25;privatestaticfinalstringusername="***@126.com";privatestaticfinalstringpassword="****";privatestaticfinalstringemailform="***@126.com";privatestaticjavamailsenderimplmailsender=createmailsender();/***邮件发送器**@return配置好的工具*/privatestaticjavamailsenderimplcreatemailsender(){javamailsenderimplsender=newjavamailsenderimpl();sender.sethost(host);sender.setport(port);sender.setusername(username);sender.setpassword(password);sender.setdefaultencoding("utf-8");propertiesp=newproperties();p.setproperty("mail.smtp.timeout","25000");p.setproperty("mail.smtp.auth","false");sender.setjavamailproperties(p);returnsender;}/***发送邮件*@paramhtml发送内容*@throwsmessagingexception异常*@throwsunsupportedencodingexception异常*/publicstaticvoidsendhtmlmail(stringhtml){try{mimemessagemimemessage=mailsender.createmimemessage();//设置utf-8或gbk编码，否则邮件会有乱码mimemessagehelpermessagehelper=newmimemessagehelper(mimemessage,true,"utf-8");messagehelper.setfrom(emailform,"wangsong");messagehelper.setto("******@163.com");messagehelper.setsubject("errorlog");messagehelper.settext(html,true);mailsender.send(mimemessage);}catch(messagingexceptione){e.printstacktrace();}catch(unsupportedencodingexceptione){e.printstacktrace();}catch(mailexceptione){e.printstacktrace();}}

logger.error(pjp.getsignature()+"error",e);//不可知异常，发送邮件errorlogmail.sendhtmlmail("时间："+newdate()+"方法："+pjp.getsignature()+"原因："+e.tostring());
