整體效果：
發(fā)送端：網(wǎng)易郵箱；接收端：qq郵箱。
1.web前端
2.在網(wǎng)易郵箱“已發(fā)送”中可以看見(jiàn)通過(guò)java代碼發(fā)送的郵件
3.同樣在qq郵箱中也可以看到這樣的效果
實(shí)現(xiàn)過(guò)程：
1.web前端（bootstrap布局）

<form action="mailAction!sendMail" method="post" name="mailForm" id="mailFormId"> <ul class="list-group"> <li class="list-group-item"> <div class="input-group"> <span class="input-group-addon" id="basic-addon1">姓名:</span> <input type="text" class="form-control" placeholder="your name" name="mailForm.name" aria-describedby="basic-addon1"> </div> </li> <li class="list-group-item"> <div class="input-group"> <span class="input-group-addon" id="basic-addon2">電話(huà):</span> <input type="text" class="form-control" placeholder="your phone" name="mailForm.phone" aria-describedby="basic-addon1"> </div> </li> <li class="list-group-item"> <div class="input-group"> <span class="input-group-addon" id="basic-addon2">郵件:</span> <input type="text" class="form-control" placeholder="your e-mail" name="mailForm.e_mail" aria-describedby="basic-addon1"> </div> </li> <li class="list-group-item" style="padding-top: 20px;"> <span class="label label-default blog-label-1">消息:</span> <br><br> <textarea rows="10" style="width:100%" name="mailForm.content" placeholder="請(qǐng)輸入消息（不要超過(guò)500個(gè)字符）"></textarea> </li> <li class="list-group-item"> <center><button onclick="$('#mailFormId').submit();" type="button" class="btn btn-success">發(fā)送郵件</button></center> </li> </ul></form> |
2.首先準(zhǔn)備一個(gè)XML的模板（<xml-body>包含的是郵件的html格式的文本）。

其中模板中會(huì)有一些標(biāo)識(shí)符，如{i}，表還是字符串的預(yù)留位置，然后通過(guò)MessageFormat格式化這樣的消息，然后將格式化后的字符串插入到模式中的適當(dāng)位置。

//得到XML的模板String XML_path = ServletActionContext.getServletContext().getRealPath("/mailTemplate")+"/myMailTemplete.xml"; String str=new ReaderXML().read(XML_path); Object[] obj=new Object[]{mailForm.getName(), mailForm.getPhone(), mailForm.getE_mail(), mailForm.getContent(), "e_mail", "left", "right", "tw", "fb"}; //MessageFormat可以格式化這樣的消息，然后將格式化后的字符串插入到模式中的適當(dāng)位置String tcontent = MessageFormat.format(str, obj); |
最終XML模板中的{i}分別被obj[i]替換了。
3.寫(xiě)一個(gè)對(duì)XML模板的類(lèi)ReaderXML

public class ReaderXML { public String read(String path){ String str=null; str=reader(path); return str; } private String reader(String path){ SAXReader reader=new SAXReader(); String str=null; try { Document d=reader.read(new File(path)); Element e=d.getRootElement(); Element htmle=e.element("html"); str=htmle.asXML(); } catch (DocumentException e) { e.printStackTrace(); } return str; }} |
4.最后就是我們的控制器類(lèi)MailAction
在 HTML 格式的正文中內(nèi)含圖片是使用MimeBodyPart類(lèi)的setContentID() 方法設(shè)置對(duì)應(yīng)的資源文件的唯一標(biāo)識(shí)符，即 MIME 協(xié)議對(duì)于郵件的結(jié)構(gòu)組織格式中的 Content-ID 頭字段，對(duì)應(yīng)著XML模板中的cid:{i}標(biāo)識(shí)， 如<img src="cid:{8}"/>（注:{i}會(huì)通過(guò)MessageFormat.format替換成對(duì)應(yīng)的字符串）
