SpringBoot整合log4j发送系统异常邮件：实时掌控你的系统健康状态

Exception Mail

由于时间宝贵，有时候写博客就没写那么详细，有什么地方不明白的话可以通过微信联系到我，我在我的某一篇文章中留下过自己的微信二维码，欢迎来骚扰....

系统发生异常时，邮件提醒

通过Log4j就可以实现这项功能，只需要简单配置一下

pom依赖去除

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <!--去除Springboot自带的日志包-->
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

log4j坐标依赖

<!--SpringBoot - log4j-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j</artifactId>
            <version>1.3.8.RELEASE</version>
        </dependency>
<!--log4j 实现发邮件必须包-->
        <dependency>
            <groupId>javax.activation</groupId>
            <artifactId>activation</artifactId>
            <version>1.1.1</version>
        </dependency>

javax.mail

<!--javax.mail-->
        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4.7</version>
        </dependency>
