① java 发送邮件，内容是要从数据库中读取的数据并列成表格的状态发送出去
其他省略，直接上邮件内容，以html格式编写：
String[] toMail = {"发送邮箱1","发送邮箱[email protected]"};
String subject = "Mark-最近一周的生产记录异常数据！！！";
//一下即为邮件内容content
String html = "<html><body><font size='15' color='black'><table align='left' border='1' cellpadding='1' cellspacing='0'>"
+ "<tr style='font-size: 16px;' height='20px' bgcolor='#DCDCDC'>"
+ "<th>BadgeNo</th><th>Shift</th><th>Section</th><th>SerialNo</th><th>DateTimeIn</th><th>TimeSpan/秒</th></tr>";
for (EMS_Outliers Outliers : list) {
html += "<tr><td>"+Outliers.getBadgeNo()+"</td><td align='center'>"+Outliers.getShift()+"</td><td>"+Outliers.getSection()+"</td><td>"
+Outliers.getSerialNo()+"</td><td>"+Outliers.getDateTimeIn()+"</td><td align='center'>"+Outliers.getTimeSpan()+"</td></tr>";
}
html += "</table></font></body></html>";
try {//一下为调用的发送邮件的方法
MailGroupSending.sendhtmlmail(mailUser, mailpwd, toMail, subject, html, null, null);
} catch (Exception e) {
e.printStackTrace();
}
② 怎么用JAVA实现邮件发送
一个小例子，也可使用其他api
importjava.util.Properties;
importjavax.mail.Address;
importjavax.mail.Authenticator;
importjavax.mail.BodyPart;
importjavax.mail.Message;
importjavax.mail.Multipart;
importjavax.mail.PasswordAuthentication;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeBodyPart;
importjavax.mail.internet.MimeMessage;
importjavax.mail.internet.MimeMultipart;
importjavax.mail.internet.MimeUtility;
publicclassTest{
//test
publicstaticvoidmain(String[]args)throwsException{
sendEmail("smtp.163.com","测试","测试","！！！收件人地址！！！","！！！发件人邮箱用户名！！！","！！！邮箱密码！！！","发件人昵称");
}
/**
*
*@paramsmtp
*@throwsException
*/
publicstaticvoidsendEmail(StringemailServer,Stringsubject,StringmailBody,Stringreceiver,finalStringusername,finalStringpassword,Stringnickname)throwsException{
Propertiesprops=newProperties();
props.put("mail.smtp.auth","true");
props.setProperty("mail.transport.protocol","smtp");
props.setProperty("mail.smtp.host",emailServer);
props.setProperty("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
props.setProperty("mail.smtp.socketFactory.fallback","false");
props.setProperty("mail.smtp.port","465");
props.setProperty("mail.smtp.socketFactory.port","465");
Sessionsession=Session.getDefaultInstance(props,newAuthenticator(){
(){
(username,password);
}
});
session.setDebug(true);
MimeMessagemimeMsg=newMimeMessage(session);
Multipartmp=newMimeMultipart();
mimeMsg.setSubject(MimeUtility.encodeText(subject,"utf-8",null));
nickname=MimeUtility.encodeText(nickname,"utf-8",null);
mimeMsg.setFrom(newInternetAddress(username,nickname,"UTF-8"));
BodyPartbp=newMimeBodyPart();
bp.setContent(mailBody,"text/html;charset=utf-8");
mp.addBodyPart(bp);
mimeMsg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(receiver));
mimeMsg.setContent(mp);
mimeMsg.saveChanges();
Transporttransport=session.getTransport();
transport.connect(username,password);
Address[]allRecipients=mimeMsg.getAllRecipients();
transport.sendMessage(mimeMsg,allRecipients);
transport.close();
}
}
③ java 发送邮件 需要哪些jar包
使用发送邮件需要用到mail.jar和activtion.jar两个包。
该类实现了较完整的邮件发送功能，包括以HTML格式发送，添加附件和抄送人。下面是具体的代码：
packagecn.cgw.util.mail;
importjava.util.Properties;
importjavax.activation.DataHandler;
importjavax.activation.FileDataSource;
importjavax.mail.Address;
importjavax.mail.BodyPart;
importjavax.mail.Message;
importjavax.mail.Multipart;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeBodyPart;
importjavax.mail.internet.MimeMessage;
importjavax.mail.internet.MimeMultipart;
publicclassMail{
privateMimeMessagemimeMsg;//MIME邮件对象
privateSessionsession;//邮件会话对象
privatePropertiesprops;//系统属性
privatebooleanneedAuth=false;//smtp是否需要认证
//smtp认证用户名和密码
privateStringusername;
privateStringpassword;
privateMultipartmp;//Multipart对象,邮件内容,标题,附件等内容均添加到其中后再生成MimeMessage对象
/**

publicMail(Stringsmtp){
setSmtpHost(smtp);
createMimeMessage();
}

publicvoidsetSmtpHost(StringhostName){
System.out.println("设置系统属性：mail.smtp.host="+hostName);
if(props==null)

props.put("mail.smtp.host",hostName);//设置SMTP主机
}
/**

returntrue;
}catch(Exceptione){

returnfalse;
}
}
