19.springboot发送mail

1.介绍

JMS即Java消息服务（Java Message Service）应用程序接口，是一个Java平台中关于面向消息中间件（MOM）的API，用于在两个应用程序之间，或分布式系统中发送消息，进行异步通信。Java消息服务是一个与具体平台无关的API，绝大多数MOM提供商都对JMS提供支持。
JMS是一种与厂商无关的 API，用来访问消息收发系统消息，它类似于JDBC(Java Database Connectivity)。这里，JDBC 是可以用来访问许多不同关系数据库的 API，而 JMS 则提供同样与厂商无关的访问方法，以访问消息收发服务。许多厂商都支持 JMS，包括 IBM 的 MQSeries、BEA的 Weblogic JMS service和 Progress 的 SonicMQ。 JMS 使您能够通过消息收发服务（有时称为消息中介程序或路由器）从一个 JMS 客户机向另一个 JMS客户机发送消息。消息是 JMS 中的一种类型对象，由两部分组成：报头和消息主体。报头由路由信息以及有关该消息的元数据组成。消息主体则携带着应用程序的数据或有效负载。根据有效负载的类型来划分，可以将消息分为几种类型，它们分别携带：简单文本(TextMessage)、可序列化的对象 (ObjectMessage)、属性集合 (MapMessage)、字节流 (BytesMessage)、原始值流 (StreamMessage)，还有无有效负载的消息 (Message)

2.建立工程

(1)pom.xml

引入mail依赖

填写一个邮箱账号

spring.mail.host=smtp.163.comspring.mail.username=[e-mail]=spring.mail.port=25spring.mail.protocol=smtpspring.mail.default-encoding=UTF-8
