随着时代不断向前发展，科学技术的不断更新变革，经济发展水平的不断提升，人们对于新技术新产业的渴求越来越强烈。这也使得java的应用越发受人看重。那么，今天就主要来为大家介绍一下，如何在java中用exchange发送邮件，并且通过实例为大家展示多次发送的操作方法。
首先，我们可以了解一下，使用Exchange Server邮件服务器发送邮件的特殊之处在于，用户名username必须添加所在域的前缀。举个例子，如果要使用域domain中的用户demo@sample.com来发送邮件，那么登录名要改成domain\demo，而不是普通stmp服务器中的demo@sample.com。接下来就通过一个实际的代码为大家展示：
import java.util.Date;
import java.util.Properties;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class Mailer
{
private String host;
private String auth;
private String username;
private String domainUser;
private String password;
public boolean send(String[] to, String[] cc, String[] bcc, String subject, String content) throws MessagingException
{
Properties props = new Properties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", auth);
Session s = Session.getInstance(props);
// s.setDebug(true);
MimeMessage message = new MimeMessage(s);
InternetAddress from = new InternetAddress(username);
message.setFrom(from);
InternetAddress[] Toaddress = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++)
Toaddress[i] = new InternetAddress(to[i]);
message.setRecipients(Message.RecipientType.TO, Toaddress);
if (cc != null)
{
InternetAddress[] Ccaddress = new InternetAddress[cc.length];
for (int i = 0; i < cc.length; i++)
Ccaddress[i] = new InternetAddress(cc[i]);
message.setRecipients(Message.RecipientType.CC, Ccaddress);
}
if (bcc != null)
{
InternetAddress[] Bccaddress = new InternetAddress[bcc.length];
for (int i = 0; i < bcc.length; i++)
Bccaddress[i] = new InternetAddress(bcc[i]);
message.setRecipients(Message.RecipientType.BCC, Bccaddress);
}
message.setSubject(subject);
message.setSentDate(new Date());
BodyPart mdp = new MimeBodyPart();
mdp.setContent(content, "text/html;charset=utf-8");
Multipart mm = new MimeMultipart();
mm.addBodyPart(mdp);
message.setContent(mm);
message.saveChanges();
Transport transport = s.getTransport("smtp");
transport.connect(host, (null == domainUser) ? username : domainUser, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
return true;
}
public Mailer(String host, String auth, String domainUser, String username, String password)
{
super();
this.host = host;
this.auth = auth;
this.domainUser = domainUser;
this.username = username;
this.password = password;
}
}调用：
new Mailer("smtp.sample.com", "true", "domain\\demo", "demo@sample.com", "password")
.send(new String[]
{
"to@mail.com"
}, null, null, "demo_title", "<h3>test</h3>");然后我们再说一下多次发送邮件的方法，主要说三种，也就是controller，jsp以及js，通过实际的代码为大家展示。
1. controller：
// 发送邮件
@ResponseBody
@RequestMapping("/fileUpdate2")
public Object tpUpdate(String con, HttpSession session, AdminEmail adminEmail, Sysnotice sys, HttpServletRequest request, Model model) throws IOException
{
//System.out.println("进入con:"+con);
String msg = null;
try
{
// 邮件发送者
String addEmail = "zhongjingzhiku@163.com";
//发送人名称
String name = "*****平台";
// 根据邮件发送者，查询邮件发送者和邮箱授权码和邮件内容
adminEmail = notifyDownService.ademail(addEmail);
//String con = request.getParameter("content");
//System.out.println("con:"+con);
adminEmail.setContent(con);
notifyDownService.insertcon(adminEmail);
// System.out.println("+++++++++:"+adminEmail.getContent());
// 邮件接收者
String[] em = notifyDownService.email();
adminEmail.setToAddress(em);
// System.out.println("adminEmail========:"+adminEmail.getToAddress().length);
// 邮件标题
adminEmail.setTitle("文件更新通知公告");
boolean flag = JavaEmailSender.sendema(adminEmail, name);
// 将信息插入到数据库
if (flag == true)
{
msg = "success";
//System.out.println("1.------------------------------------");
//session.setAttribute("msg",msg);
//System.out.println("-------------------------:"+msg);
//String conc = request.getParameter("content");
sys.setNoticecont(con);
sys.setNoticetype(adminEmail.getTitle());
sys.setNoticetime(new Date());
notifyDownService.insertSys(sys);
}
else
{
msg = "fail";
session.setAttribute("msg", msg);
}
}
catch (Exception e)
{
e.printStackTrace();
}
// 在消息表里插入未读消息
mymessageService.addMessagebyType2();
return new JsonResult(msg);
}2. jsp:
<div class="form-x"> <div class="form-group"> <div class="label" style="width: 80px;float: left;line-height: 40px;"> <label>通知内容</label> </div> <div class="field" id="nr"> <textarea id="text" class="input" name="content" style=" height:90px;" data-validate="required:内容不为空" required maxlength="30">最多输入30字符</textarea> <div class="tips"></div> </div> </div> <div class="form-group"> <div class="label"> <label></label> </div> <input type="hidden" name="templateid" value="3057810"/><!-- 文件更新通知短信模板id --> <div class="field"> <button id="send" class="button bg-main" data-toggle="modal" data-target="#myModal" onclick="submit()">发送</button> </div> </div> </div>
3. js:
function submit()
{
var path = window.document.location.href.substring(0, window.document.location.href.indexOf(window.document.location.pathname)) + window.document.location.pathname.substring(0, window.document.location.pathname.substr(1)
.indexOf('/') + 1);
var con = $("#text")
.val();
$.ajax(
{
type: "POST"
, url: path + "/fileUpdate2"
, data:
{
"con": con
}
, dataType: "json"
, success: function (result)
{
var msg = result.data;
if (msg == "success")
{
$.MsgBox.Alert("温馨提示", "发送成功!");
}
else if (msg == "fail")
{
$.MsgBox.Alert("温馨提示", "发送失败！");
}
}
});
