环境: Spring Boot 2.1.5.RELEASE 、Java 8
构建环境
在pom.xml
文件中加入依赖
<!-- Thymeleaf 模板引擎 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<!-- 发送邮件 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
在application.properties
文件中加入163邮箱的配置
## 发送邮件配置
spring.mail.host=smtp.163.com # 163邮箱的smtp
spring.mail.port=25 # 端口,
spring.mail.username=邮箱的用户名
spring.mail.password=邮箱的授权码(不是登录密码)
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
163邮箱的收取邮件支持POP/IMAP两种协议,发送邮件采用SMTP协议,收件和发件均使用SSL协议来进行加密传输,采用SSL协议需要单独对帐户进行设置。采用SSL协议和非SSL协议时端口号有所区别,参照下表的一些常见配置组合:
类型 | 服务器名称 | 服务器地址 | SSL协议端口号 | 非SSL协议端口号 |
---|---|---|---|---|
收件服务器 | POP | pop.163.com | 995 | 110 |
收件服务器 | IMAP | imap.163.com | 993 | 143 |
发件服务器 | SMTP | smtp.163.com | 465/994 | 25 |
163邮箱的地址和端口: http://help.163.com/10/0731/11/6CTUBPT300753VB8.html
