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;

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 recipie
b1cc
nt = 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 = "a@126.com";
String to = "b@126.com,c@126.com";
String cc = "d@126.com,e@126.com";
String bcc = "f@126.com";
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", "a@126.com", "password", affix, from, to, cc, bcc, title, content);

就这么多了
