<content type="html"><![CDATA[<h1 id="缓存介绍"><a href="#缓存介绍" class="headerlink" title="缓存介绍"></a>缓存介绍</h1><blockquote><p>Spring3.1之后引入了基于注释（annotation）的缓存（cache）技术，它本质上不是一个具体的缓存实现方案（如EHCache 或者Redis），而是一个对缓存使用的抽象，通过在既有代码中添加少量它定义的各种annotation，即能够达到缓存方法的返回对象的效果。</p></blockquote><blockquote><p>Spring的缓存技术还具备相当的灵活性，不仅能够使用 SpEL（Spring Expression Language）来定义缓存的key和各种condition，还提供开箱即用的缓存临时存储方案，也支持和主流的专业缓存，例如Redis、EHCache集成。</p></blockquote><p>Spring Cache位于spring-content中，如下图<br><img src="http://img.xujn.xyz/20200914154543.png?!"></p><h1

class="headerlink" title="POP3 接收邮件服务器"></a>POP3 接收邮件服务器</h2><blockquote><p> <strong>POP3</strong>是Post Office Protocol 3的简称，即邮局协议的第3个版本,它规定怎样将个人计算机连接到Internet的邮件服务器和下载电子邮件的电子协议。它是因特网电子邮件的第一个离线协议标准,POP3允许用户从服务器上把邮件存储到本地主机（即自己的计算机）上,同时删除保存在邮件服务器上的邮件，而POP3服务器则是遵循POP3协议的接收邮件服务器，用来接收电子邮件的。</p></blockquote><h2 id="IMAP-接收邮件服务器"><a href="#IMAP-接收邮件服务器" class="headerlink" title="IMAP 接收邮件服务器"></a>IMAP 接收邮件服务器</h2><blockquote><p> <strong>IMAP</strong>全称是Internet Mail Access Protocol，即交互式邮件存取协议，它是跟POP3类似邮件访问标准协议之一。不同的是，开启了IMAP后，您在电子邮件客户端收取的邮件仍然保留在服务器上，同时在客户端上的操作都会反馈到服务器上，如：删除邮件，标记已读等，服务器上的邮件也会做相应的动作。所以无论从浏览器登录邮箱或者客户端软件登录邮箱，看到的邮件以及状态都是一致的。</p></blockquote><h2 id="SMTP-发送邮件服务器"><a href="#SMTP-发送邮件服务器" class="headerlink" title="SMTP 发送邮件服务器"></a>SMTP 发送邮件服务器</h2><blockquote><p><strong>SMTP</strong> 的全称是“Simple Mail Transfer Protocol”，即简单邮件传输协议。它是一组用于从源地址到目的地址传输邮件的规范，通过它来控制邮件的中转方式。SMTP 协议属于 TCP/IP 协议簇，它帮助每台计算机在发送或中转信件时找到下一个目的地。SMTP 服务器就是遵循 SMTP 协议的发送邮件服务器。SMTP 认证，简单地说就是要求必须在提供了账户名和密码之后才可以登录 SMTP 服务器，这就使得那些垃圾邮件的散播者无可乘之机。增加 SMTP 认证的目的是为了使用户避免受到垃圾邮件的侵扰。 </p></blockquote><h1 id="项目依赖"><a href="#项目依赖" class="headerlink" title="项目依赖"></a>项目依赖</h1><figure class="highlight plaintext"><table><tbody><tr><td
