一、准备工作：开启SMTP获取授权码
以 163 邮箱为例，首先登录邮箱之后，在设置中开启 SMTP，如下图所示：
二、添加依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId>
</dependency>三、设置配置
spring:mail:host: smtp.163.comusername: xxx# 邮箱授权码，不是邮箱密码，开通SMTP、POP时得到的授权码password: xxx四、编写代码

@RequestMapping("/mail")
