#logback打印錯誤日誌到郵箱 須要依賴的jar文件：janinohtml

<log.janino.version>2.7.8</log.janino.version>

pom.xml配置以下：java

<dependency>
	<groupId>org.codehaus.janino</groupId>
	<artifactId>janino</artifactId>
	<version>${log.janino.version}</version>
</dependency>
<!-- email -->
		<dependency>
			<groupId>javax.mail</groupId>
			<artifactId>mail</artifactId>
			<version>1.4.7</version>
		</dependency>
		<!-- email END-->

若是沒有添加 mail 依賴會出現如下錯誤：express

1.準備郵件配置項

定義文件名稱：logback.propertiesapache

LOG_PATH=D\:/logs/mall/mall-soonew
smtpHost=smtp.163.com  
smtpPort=25  
username=xxxxx@163.com  
password=xxxxxx
SSL=false  
email_to=xxx@qq.com,zyq@xxx.com  
email_from=xx@163.com  
email_subject=\u3010Error\u3011\: %logger  
localhost=www.huaqinwang.com

2.logback.xml文件中引入配置項

logback.xml配置文件添加以下內容：tomcat

<property file="建議絕對路徑/logback.properties" />
 <property resource="類路徑下/logback.properties" />
  
    <appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">  
        <smtpHost>${smtpHost}</smtpHost>  
        <smtpPort>${smtpPort}</smtpPort>  
        <username>${username}</username>  
        <password>${password}</password>
        <localhost>${localhost}</localhost>  
        <SSL>${SSL}</SSL>  
        <asynchronousSending>true</asynchronousSending>  
        <to>${email_to}</to>  
        <from>${email_from}</from>  
        <subject>${email_subject}</subject>  
        <layout class="ch.qos.logback.classic.html.HTMLLayout" >  
            <pattern>%date%level%thread%logger{0}%line%message</pattern>  
        </layout>  
        
        <filter class="ch.qos.logback.core.filter.EvaluatorFilter">    
            <evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator">  
                <expression>  <!-- &amp;&amp; null != throwable -->
                    if(level >= WARN ) {  
                        return true;  
                    }  
                    return false;  
                </expression>    
            </evaluator> 
            <!-- <level>error</level>    -->
            <onMatch>ACCEPT</onMatch>    
            <onMismatch>DENY</onMismatch>      
        </filter>  
	</appender> 
............ 
    <root  level="INFO">
	<appender-ref ref="EMAIL"/>  	
    </root>

3.效果截圖

QQ郵箱： qq郵箱顯示效果 163郵箱： 163郵箱顯示效果服務器

4.參考網址

logback使用說明app

5.線上異常

項目生產環境運營正常logback.xml文件的部分文件配置爲：異步

<asynchronousSending>false</asynchronousSending>

異步發送郵件=false 變動爲同步發送。 問題：若是配置的發送郵箱服務器出現了問題沒法發送時拋異常會把項目生產環境部署在tomcat的服務重啓，就這樣折騰了6個小時細心的同事註釋了logger.error結果正常了。async
