spring-boot-mail
记录下邮箱的操作。
依赖：spring-boot-starter-mail/spring-boot-starter-test（测试用）/spring-boot-starter-thymeleaf（模板，velocity等也行，只是跟parent的版本要匹配，我用velocity不能使用1.5.9的parent，1.3.2的可以）
----------------------------------------------------------------------------------------------
配置文件properties：
spring.application.name=spirng-boot-mail
#使用163的，其他的也可以
spring.mail.host=smtp.163.com
#你的真实163邮箱，不是这里的xxx啊
#你的163授权密码，不是邮箱登录密码。见下面说明
spring.mail.password=xxx
spring.mail.default-encoding=UTF-8
#从哪里发出，当然也是你的邮箱啦
[email protected]
这里，设置里面点圈住的，然后开启服务，设置你的授权密码，在这里登录用的是授权密码。

准备一个简单模板：
<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8"/>
<title>Title</title>
</head>
<body>
您好,你懂的<br/>
<a href="#" th:href="@{ xxx/{id}(id=${id}) }">点此</a>
</body>
</html>

省略Service接口，直接上实现类，可以多种姿势发邮件啦：
