【前言】
Spring Boot Admin做为生产级的监控工具，必然自动化告警必不可少；Spring Boot Admin可以十分简单的集成告警组件；最近研究一下集成邮件告警到项目中，在此与大家共享；
【集成告警模块】
一、集成告警模块（在此以邮件告警为例）
1、Spring Boot Admin服务端集成（以zh-monitor为例）
（1）Pom中增加邮箱依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
（2）配置文件（application.properties）中增加邮箱相关配置
#****************************alerm email*************************** spring.mail.host=smtp.163.com spring.mail.username=from@163.com #注意:此密码为客户端的授权码而非邮箱密码 spring.mail.password=xxxxx spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.starttls.enable=true spring.mail.properties.mail.smtp.starttls.required=true spring.boot.admin.notify.mail.from=from@163.com spring.boot.admin.notify.mail.to=to@163.com
（3）启动zh-monitor报错处理
A.报错信息如下:
javax.mail.AuthenticationFailedException: 535 Error: authentication failed at com.sun.mail.smtp.SMTPTransport$Authenticator.authenticate(SMTPTransport.java:965) ~[javax.mail-1.6.2.jar:1.6.2] at com.sun.mail.smtp.SMTPTransport.authenticate(SMTPTransport.java:876) ~[javax.mail-1.6.2.jar:1.6.2] at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:780) ~[javax.mail-1.6.2.jar:1.6.2] at javax.mail.Service.connect(Service.java:366) ~[javax.mail-1.6.2.jar:1.6.2] at org.springframework.mail.javamail.JavaMailSenderImpl.connectTransport(JavaMailSenderImpl.java:515) ~[spring-context-support-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.mail.javamail.JavaMailSenderImpl.testConnection(JavaMailSenderImpl.java:396) ~[spring-context-support-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.boot.actuate.mail.MailHealthIndicator.doHealthCheck(MailHealthIndicator.java:43) ~[spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.actuate.health.AbstractHealthIndicator.health(AbstractHealthIndicator.java:84) ~[spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.actuate.health.CompositeHealthIndicator.health(CompositeHealthIndicator.java:98) [spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.actuate.health.HealthEndpoint.health(HealthEndpoint.java:50) [spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_144] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_144] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_144] at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_144] at org.springframework.util.ReflectionUtils.invokeMethod(ReflectionUtils.java:246) [spring-core-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.boot.actuate.endpoint.invoke.reflect.ReflectiveOperationInvoker.invoke(ReflectiveOperationInvoker.java:76) [spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.actuate.endpoint.annotation.AbstractDiscoveredOperation.invoke(AbstractDiscoveredOperation.java:61) [spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.actuate.endpoint.jmx.EndpointMBean.invoke(EndpointMBean.java:126) [spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.actuate.endpoint.jmx.EndpointMBean.invoke(EndpointMBean.java:99) [spring-boot-actuator-2.1.1.RELEASE.jar:2.1.1.RELEASE] at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanServerInterceptor.java:819) [na:1.8.0_144] at com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:801) [na:1.8.0_144] at javax.management.remote.rmi.RMIConnectionImpl.doOperation(RMIConnectionImpl.java:1468) [na:1.8.0_144] at javax.management.remote.rmi.RMIConnectionImpl.access$300(RMIConnectionImpl.java:76) [na:1.8.0_144] at javax.management.remote.rmi.RMIConnectionImpl$PrivilegedOperation.run(RMIConnectionImpl.java:1309) [na:1.8.0_144] at javax.management.remote.rmi.RMIConnectionImpl.doPrivilegedOperation(RMIConnectionImpl.java:1401) [na:1.8.0_144] at javax.management.remote.rmi.RMIConnectionImpl.invoke(RMIConnectionImpl.java:829) [na:1.8.0_144] at sun.reflect.GeneratedMethodAccessor46.invoke(Unknown Source) ~[na:na] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_144] at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_144] at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:357) [na:1.8.0_144] at sun.rmi.transport.Transport$1.run(Transport.java:200) [na:1.8.0_144] at sun.rmi.transport.Transport$1.run(Transport.java:197) [na:1.8.0_144] at java.security.AccessController.doPrivileged(Native Method) [na:1.8.0_144] at sun.rmi.transport.Transport.serviceCall(Transport.java:196) [na:1.8.0_144] at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:568) [na:1.8.0_144] at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:826) [na:1.8.0_144] at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.lambda$run$0(TCPTransport.java:683) [na:1.8.0_144] at java.security.AccessController.doPrivileged(Native Method) [na:1.8.0_144] at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:682) [na:1.8.0_144] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[na:1.8.0_144] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[na:1.8.0_144] at java.lang.Thread.run(Thread.java:748) ~[na:1.8.0_144]
B.报错原因：配置的邮箱不允许客户端访问，授权码不正确
C.解决方案：开启客户端授权登录，并在配置文件中配置正确授权码；在此以163邮箱为例
2、Spring Boot Admin客户端无需改动
二、查看效果
1、启动zh-boot
2、启动zh-monitor
3、停止zh-boot项目，收到服务停止邮件
4、启动zh-boot项目，收到服务启动邮件
三、项目地址：
1、地址：https://github.com/dangnianchuntian/springboot
2、代码版本：1.6.0-Release
【总结】
1、自动化告警是生产级别项目必不可少一个重要组成部分，有了告警可以让我们知道线上项目发生了什么；
2、接下来会为大家共享多关于SpringBootAdmin模块。
