SpringBoot 集成 E-mail发送邮件，供大家参考，具体内容如下
JDK本身有自带发送邮件api，加上SpringBoot在进行封装，使得现在使用起来十分快速简洁。
话不多说，参考纯洁的微笑博客，更改jar版本为2.0.4 开干，基本没什么坑。
就是配置邮箱账号密码是，如果是qq邮箱，需要开启PO30和STMP服务，并且获取临时授权码。
开启服务链接：
https://mail.qq.com/cgi-bin/frame_html?sid=a5ZSbreeNm9pHyl1&r=a83225170e94773c650a460c10f7a05c
与Springboot集成
导入jar包
compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail', version: '2.0.4.RELEASE' compile 'org.springframework.boot:spring-boot-starter-thymeleaf:2.0.4.RELEASE'
配置邮箱
#邮箱服务器地址，各大运营商不同 spring.mail.host=smtp.qq.com #用户名 spring.mail.username=9118542413@qq.com #密码，如果是qq的，要申请临时授权码 spring.mail.password=faw124awfawfawg spring.mail.default-encoding=UTF-8 #以谁来发送邮件 mail.fromMail.addr=9118542413@qq.com

上面的邮箱和密码是我乱填的，注意自己更改。
