java mail 发送邮件

能抄送、密送、附件
注意：1、javaMail需要一个Properties来注册Session
2、邮箱密码是用邮箱里面对stmp的授权码 而不是登录密码
3、用到两个jar包 mail.jar和activator.jar

MailSender.java

import java.io.File;import java.util.Properties;import javax.activation.DataHandler;import javax.activation.DataSource;import javax.activation.FileDataSource;import javax.mail.BodyPart;import javax.mail.Message;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;import javax.mail.internet.MimeUtility;public class MailSender {    private String host = ""; // smtp    private String from = ""; // 发件地址    private String to = ""; // 收件地址    private String cc = ""; //抄送地址    private String bcc = "";//密送地址    private String affix = ""; // 附件地址    private String user = ""; // 发件邮箱名    private String pwd = ""; // 邮箱stmp授权码    private String subject = ""; // 邮件标题    private String content = "";// 邮件内容    public void send(String host, String user, String pwd,File attachment,String from, String to, String cc , String bcc , String subject,String content) {        this.host = host;        this.user = user;        this.pwd = pwd;        this.from = from;        this.to = to;        this.cc = cc;        this.bcc = bcc;        this.subject = subject;        this.content = content;        Properties props = new Properties();        // 设置邮箱服务器的Properties        props.put("mail.smtp.host", host);        // 设置通过服务器认证        props.put("mail.smtp.auth", "true");        // 创建一个 session        Session session = javax.mail.Session.getInstance(props);        // 开启debug模式 可以logcat上看发件时的信息        session.setDebug(true);        MimeMessage message = new MimeMessage(session);        try {            Multipart multipart = new MimeMultipart();            // 设置发件地址            message.setFrom(new InternetAddress(from));            // 设置接收地址            //多个收件地址            String[] eachRecipients = null;            eachRecipients = to.split("\\|");            for(int i=0;i<eachRecipients.length;i++){                String recipient = eachRecipients[i];                message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));            }            //多个抄送地址            String[] cceachRecipients = null;            cceachRecipients=cc.split("\\|");            for(int i=0;i<cceachRecipients.length;i++){                String recipient = cceachRecipients[i];                message.addRecipient(Message.RecipientType.CC, new InternetAddress(to));            }            //密送地址            message.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc));            // 设置邮件标题            message.setSubject(subject);            // 设置邮件内容            BodyPart contentPart = new MimeBodyPart();            contentPart.setText(content);            multipart.addBodyPart(contentPart);            // 设置附件            if (attachment != null) {                BodyPart attachmentBodyPart = new MimeBodyPart();                DataSource source = new FileDataSource(attachment);                attachmentBodyPart.setDataHandler(new DataHandler(source));                //防止附件发出后中文变乱码                attachmentBodyPart.setFileName(MimeUtility.encodeWord(attachment.getName()));                multipart.addBodyPart(attachmentBodyPart);            }            message.setContent(multipart);            message.saveChanges();            Transport transport = session.getTransport("smtp");            // 连接服务器            transport.connect(host, user, pwd);            // 发送            transport.sendMessage(message, message.getAllRecipients());            transport.close();        } catch (Exception e) {            e.printStackTrace();        }    }}

调用的时候就这样

File affix = new File("D:/AAAAAA.xls");        String from = "[e-mail]";        String to = "[e-mail],[e-mail]";        String cc = "[e-mail],[e-mail]";        String bcc = "[e-mail]";        String title = "邮件标题 asddfad";        String content = "邮件内容aadsfasdf12334#！！#%￥#￥…………&（&*+——“：？";        MailSender cn = new MailSender();        // 设置smtp服务器以及邮箱的帐号和密码        cn.send("smtp.126.com", "[e-mail]", "password", affix, from, to, cc, bcc, title, content);

就这么多了
