IntelliJ IDEA 2022.2.5 (Ultimate Edition) (注意idea必须在2021版本以上JDK17
项目目录 该项目分为pojo,service,controller,utils四个部分 在pojo层里面写实体内容发邮件需要的发件人邮箱授权码服务器域名身份验证开关 service层里面写send方法 utils里面写发送邮件实现的工具类 controller层里面调用service里面的方法测试send方法。 在resource里面的application.yml写相关的发邮件参数usercodehostauth 前提
该项目涉及到了邮件的发送所以需要邮箱的授权码
怎么获取授权码
在 账号与安全 --安全设置--SMTP/IMAP服务 中开启服务并获取授权码 代码
