SpringBoot整合郵箱mail發(fā)送，javax內(nèi)置郵箱mail發(fā)送

直接引入整合后的官方依賴

一、Springboot整合mail

配置

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>



以QQ郵箱為例，開啟授權(quán)碼，粘貼到配置文件中的password項(xiàng)

https://mail.qq.com/

application.yml配置

spring:
  mail:
    #smtp服務(wù)主機(jī)  qq郵箱則為smtp.qq.com、smtp.163.com
    host: smtp.qq.com
    #服務(wù)協(xié)議
    protocol: smtp
    # 編碼集
    default-encoding: UTF-8
    #發(fā)送者郵件的賬戶
    username: 599999999@qq.com
    #發(fā)送者郵箱授權(quán)碼
    password: sadfasdggh
    test-connection: true
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true

后續(xù)邏輯根據(jù)自己業(yè)務(wù)來
例如：郵箱校驗(yàn)用戶(類似于手機(jī)號(hào)校驗(yàn))、定時(shí)任務(wù)郵箱推送xx信息


pom.xml引入maven依賴

<!-- https://mvnrepository.com/artifact/javax.mail/mail -->
