SpringBoot2.x邮件发送
作者：互联网
1、pom引入依赖
<!--邮件发送-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
<!--邮件模板-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
2、application.yml增加配置
#邮件配置
mail:
host: mail.qq.com
default-encoding: UTF-8
username: test@qq.com
password: 123456
recipients: 23323@qq.com
properties:
mail:
smtp:
auth: true
ssl:
enable: false
starttls:
enable: false
required: false
3、封装邮件发送工具类
