后续，应该会写个基于springBoot的邮件服务，这个就不详细说了，引入javax里面的那个邮件包，引入下 基本就行了。
实现类：
package com.mocha.cms.utils;
import java.io.File;
import java.security.GeneralSecurityException;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import javax.mail.internet.MimeMessage;

import org.slf4j.LoggerFactory;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import com.sun.mail.util.MailSSLSocketFactory;
public class EmailUtils {
private static final Logger logger = LoggerFactory.getLogger(EmailUtils.class);
/**

*/
public static boolean sendEmail(String subject, String[] toUsers, String[] ccUsers, String content,
List> attachfiles) {
boolean flag = true;
try {
JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
javaMailSender.setHost(PropertyUtil.getValue("mail.host"));

Properties properties = new Properties();
properties.setProperty("mail.smtp.auth", PropertyUtil.getValue("mail.auth.name"));
properties.setProperty("mail.smtp.timeout", PropertyUtil.getValue("mail.smtp.timeout"));
MailSSLSocketFactory sf = null;
try {

sf.setTrustAllHosts(true);
properties.put("mail.smtp.ssl.enable", "true");
properties.put("mail.smtp.ssl.socketFactory", sf);
} catch (GeneralSecurityException e) {
e.printStackTrace();
};
javaMailSender.setJavaMailProperties(properties);
MimeMessage mailMessage = javaMailSender.createMimeMessage();
MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true);
messageHelper.setTo(toUsers);
if (ccUsers != null && ccUsers.length > 0) {

}

}
javaMailSender.send(mailMessage);
} catch (Exception e) {
logger.error("发送邮件失败!", e);
flag = false;
}
return flag;
}
public static void main(String[] args) {
String[] toUsers = new String[1];
toUsers[0] = "[email protected]";
EmailUtils.sendEmail("test", toUsers, null, "text-content", null);
}
}
配置文件：
mail.host=smtp.163.com
[email protected]
mail.auth.password=授权码
mail.smtp.auth=true
mail.transport.protocol=smtp
mail.send.charset=UTF-8
mail.smtp.timeout=5000
----------或者实现类--------
实现类：
@Override
public void sendEamil(Mail mail, List fileName) {
// 与smtp服务器建立一个链接
Properties p = new Properties();
try {
// 指定邮件服务器，默认端口 25
p.setProperty("mail.host", PropertyUtil.getValue("mail_host"));
// 要采用指定用户名密码的方式去认证
p.setProperty("mail.smtp.auth", "true");
// 发送邮件协议名称
p.setProperty("mail.transport.protocol", "smtp");
// 开启SSL加密，否则会失败
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
p.put("mail.smtp.ssl.enable", "true");
p.put("mail.smtp.ssl.socketFactory", sf);
// 创建session
Session session = Session.getInstance(p);
// 通过session得到transport对象
Transport ts = session.getTransport();
// 连接邮件服务器：邮箱类型，帐号，授权码代替密码（更安全）
ts.connect(PropertyUtil.getValue("mail_host"), PropertyUtil.getValue("mail_username"), PropertyUtil.getValue("mail_password"));
// 声明一个Message对象(代表一封邮件),从session中创建
MimeMessage msg = new MimeMessage(session);
// 邮件信息封装
// 1发件人
msg.setFrom(new InternetAddress(PropertyUtil.getValue("mail_username")));
// 2收件人
msg.setRecipient(RecipientType.TO, new InternetAddress(PropertyUtil.getValue("mail_addr")));
// 3邮件内容:主题
msg.setSubject(mail.getSubject());
// 邮件内容部分1---文本内容
MimeBodyPart body0 = new MimeBodyPart(); // 邮件中的文字部分
body0.setContent(mail.getContent(), "text/html;charset=utf-8");
MimeMultipart mm = new MimeMultipart();
mm.addBodyPart(body0);
// 添加附件部分
List listFile = mail.getListFile();
if(listFile != null && !listFile.isEmpty()) {
int index = 0;
for (File file : listFile) {
MimeBodyPart body = new MimeBodyPart();
body.setDataHandler(new DataHandler(new FileDataSource(file)));
body.setFileName(fileName.get(index));
mm.addBodyPart(body);
index++;
};
}
msg.setContent(mm);
// 发送邮件
ts.sendMessage(msg, msg.getAllRecipients());
ts.close();
} catch (Exception e) {
e.printStackTrace();
}
}
