说明

spring提供了非常好用的JavaMailSender接口实现了邮件的发送，其中Spring Boot的Starter也为此提供了自动化配置
QQ邮箱需要发送方开启smtp和获取授权码，开启方法：http://service.mail.qq.com/cgi-bin/help?subtype=1&&no=1001256&&id=28

      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-mail</artifactId>
          <version>2.0.2.RELEASE</version>
      </dependency>

application.properties配置

# 发送方电子邮箱服务器，如果是163就是stmp.163.com
spring.mail.host=smtp.qq.com
# 发送方邮箱
spring.mail.username=发送方邮箱
# 如果是QQ邮箱，就是发送方授权码
spring.mail.password=发送方授权码
# 通过验证
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
