前言：以前都是直接用Java自带的邮件工具发送邮件，现在Spring帮我们做了封装，提供了更好用更简单的发送邮件工具JavaMailSender，关于邮件服务器的设置就不在这里说了，直接去QQ邮箱设置下就好，下面看下主要的步骤：
步骤一、添加发送邮件相关Maven依赖

<!-- Spring 邮件发送 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.3.2.RELEASE</version> </dependency> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.7</version> </dependency> |
步骤二、添加相关Spring配置，创建一个spring-mail.xml（如果是Spring-Boot请无视）,内容如下：

OK，到这里全部的步骤就结束了，是不是比Java Mail简单方便很多哉，赶紧自己动手试试吧！
