最近在學習微服務(wù)框架Spring Cloud，把自己小項目中的郵件相關(guān)模塊拆分出來單獨構(gòu)建了一個通知中心微服務(wù)，以后發(fā)送郵件，擴展短信通知等就可以在這個微服務(wù)中單獨擴展了。
本來想著把系統(tǒng)異常也作為消息發(fā)送給通知中心微服務(wù)，但是感覺代碼會很繁瑣，雖然SpringBoot有統(tǒng)一異常管理方式，但也并不是真的所有異常都能通過這種方式處理。
然后發(fā)現(xiàn)slf4j可以通過配置xml配置增加appender來將ERROR級別的日志發(fā)送給指定的郵箱。
如下是完整的配置

主要涉及到的配置如下。通過springProperty來引用application.properties中配置的郵箱配置。
<springProperty scope="context" name="appName" source="spring.application.name" defaultValue="ApplicationName"/>
<springProperty scope="context" name="applicationStack" source="application.stack" defaultValue="beta"/>
<springProperty scope="context" name="smtpHost" source="spring.mail.host"/>

<springProperty scope="context" name="username" source="spring.mail.username"/>
<springProperty scope="context" name="mailTo" source="tendency.system.emails"/>
<springProperty scope="context" name="password" source="spring.mail.password"/>
<appender name="MAIL" class="ch.qos.logback.classic.net.SMTPAppender">

<filter class="ch.qos.logback.classic.filter.ThresholdFilter">

</filter>
</appender>

如下圖是收到郵件的效果圖，還不錯吧，哈哈，都給格式化好了
