1、首先在项目中导入jar包,我用的是mail-1.4.jar
2、一下是我的代码:
public class SendMailUtil {
private static final Logger logger = Logger.getLogger(SendMailUtil.class);
// 定义发件人、收件人、主题等
private String to = null;// 收件人邮箱地址
private String from = null;// 发件人邮箱地址
private String password = null;//发件人密码
private String host = null;//邮件服务器
private String filename = null;
// 用于保存发送附件的文件路径名的集合
private Vector<String> fileList = new Vector<String>();
/*
* 可以传发件人等参数的构造
*/
public SendMailUtil(String to, String from, String password,
String smtpServer) {
// 初始化发件人、收件人、主题等
this.to = to;
this.from = from;
this.password = password;
this.host = smtpServer;
}
/*
* 该方法用于收集附件名
*/
public void attachfile(String fname) {
fileList.addElement(fname);
}
/*
* 开始发送信件的方法
*/
public boolean startSend(String emailTitle, String emailContent) {
if (StringUtils.isBlank(emailContent)) {
logger.error("邮件内容不能为空!");
return false;
}
try {
if (StringUtils.isBlank(emailContent)) {
throw new NullPointerException("发送的内容不能为空!");
}
// 创建Properties对象
Properties props = System.getProperties();
// 创建信件服务器
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.password", "0");
// 得到默认的对话对象
Session session = Session.getInstance(props,
new PopupAuthenticator(this.from, this.password));
// 创建一个消息,并初始化该消息的各项元素
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = { new InternetAddress(to) };
msg.setRecipients(Message.RecipientType.TO, address);
// getBytes("ISO-8859-1")
// String title=new String(emailTitle.getBytes("ISO-8859-1"),"GBK");
msg.setSubject(emailTitle);
// 后面的BodyPart将加入到此处创建的Multipart中
Multipart mp = new MimeMultipart("subtype");
// 添加HTML正文
BodyPart htmlBody = new MimeBodyPart();
MimeMultipart htmlContent = new MimeMultipart("related");
BodyPart msgContent = new MimeBodyPart();
htmlContent.addBodyPart(msgContent);
msgContent.setContent(emailContent, "text/html;charset=utf-8");
htmlBody.setContent(htmlContent);
mp.addBodyPart(htmlBody);
// 利用枚举器方便的遍历集合
Enumeration efile = fileList.elements();
// 检查序列中是否还有更多的对象
while (efile.hasMoreElements()) {
MimeBodyPart mbp = new MimeBodyPart();
// 选择出每一个附件名
filename = efile.nextElement().toString();
// 得到数据源
FileDataSource fds = new FileDataSource(filename);
// 得到附件本身并至入BodyPart
mbp.setDataHandler(new DataHandler(fds));
// 得到文件名同样至入BodyPart
mbp.setFileName(fds.getName());
mp.addBodyPart(mbp);
}
// 移走集合中的所有元素
fileList.removeAllElements();
// Multipart加入到信件
msg.setContent(mp);
// 设置信件头的发送日期
msg.setSentDate(new Date());
// 发送信件
Transport.send(msg);
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
// 认证类
class PopupAuthenticator extends Authenticator {
private String username ;
private String password ;
public PopupAuthenticator(String user, String pass) {
this.username = user;
this.password = pass;
}
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
}
//测试
public static void main(String[] args) {
SendMailUtil mail = new SendMailUtil("qinkui_java@163.com",
"test@163.com","123456", "smtp.163.com");
mail.attachfile("C:\\Users\\awen\\Desktop\\a.txt");
mail.startSend("交接文档","收到请回复");
System.out.println("邮件发送完成...");
}
3、测试成功,大家可以试一下。
