springboot项目中如何实现邮件告警功能(监控平台服务模拟)

介绍

模拟服务器故障，然后实现邮件告警

一、首先配置邮件的maven依赖

代码如下：

<!--邮件告警--><!-- Spring Boot的邮件发送依赖 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><dependency><groupId>com.sun.mail</groupId><artifactId>javax.mail</artifactId><version>1.6.2</version></dependency>

二、其次在ideal中创建相关类文件

2.1、创建一个服务类MonitoringService

使用Spring的JavaMailSender来发送邮件。

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;/*** Created by 姜水桦 on 2024/3/21 16:58* 功能描述:*         创建一个服务类，使用Spring的JavaMailSender来发送邮件。*/
@Service
public class MonitoringService {private final JavaMailSender mailSender;public MonitoringService(JavaMailSender mailSender) {this.mailSender = mailSender;}public void sendAlertEmail(String from,String to, String subject, String text) {SimpleMailMessage message = new SimpleMailMessage();message.setFrom(from);message.setTo(to);message.setSubject(subject);message.setText(text);mailSender.send(message);}
}

2.2、定义一个监控类

        在你的监控组件中，当检测到异常时，调用EmailService的sendAlertEmail方法来发送邮件。

package com.example.service;import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;/*** Created by 姜水桦 on 2024/3/21 16:58* 功能描述:*         创建一个服务类，使用Spring的JavaMailSender来发送邮件。*/
@Service
public class MonitoringService {private final JavaMailSender mailSender;public MonitoringService(JavaMailSender mailSender) {this.mailSender = mailSender;}public void sendAlertEmail(String from,String to, String subject, String text) {SimpleMailMessage message = new SimpleMailMessage();message.setFrom(from);message.setTo(to);message.setSubject(subject);message.setText(text);mailSender.send(message);}
}

2.3、再创建一个控制器类(逻辑层)

EmailController

package com.example.controller;import com.example.common.AuthAccess;
import com.example.utils.ServiceMonitor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;/*** Created by 姜水桦 on 2024/3/21 19:53* 功能描述:*/
@RestController
public class EmailController {@Autowiredprivate ServiceMonitor serviceMonitor;// 每隔30秒执行一次checkServiceStatus方法
//    @Scheduled(fixedRate = 30000)
//    @Scheduled(fixedRate = 1000)@GetMapping("/mail")@AuthAccesspublic void monitorService() {serviceMonitor.checkServiceStatus();}
}

2.4、配置application.yml

spring:#邮箱配置mail:host: smtp.qq.comport: 465# 使用自己的发送方用户名 + 授权码填充username: jiangshuihua1018@qq.compassword: vyqsovsepomlecdddefault-encoding: UTF-8properties:mail:smtp:ssl:enable: falserequired: falsesocketFactory:class: javax.net.ssl.SSLSocketFactoryallow8bitmime: truedebug: true

注意：这里的密码指的是你QQ账号里面的授权码
