邮件发送

1、UtilTools.sendMail(to, to, subject, body.toString());

参数说明：

第一个to：收件人  “yongzhian@huawei.com;”主送多个人，to用";"隔开
第二个to：收件人  “yongzhian@huawei.com;”抄送多个人, 用";"隔开
subject：主题
body:内容 即html

2、实现类

EmailBase.getInstance().SendEmailsTCB(to, "","",subject, body);
EmailBase采用单例，私有属性，
    private String mail_smtp_host;
    private String username;
    private String password;
    private String from;
    private String fromname;
    private String to; 
    private String cc;
    private String bcc;
    private String toname;
    private String subject;
    private String body;
    private String authenticator;
    private Properties prp;
    private static EmailBase emailBase;
初始化“
init(){
 prp = new Properties();
        ResourceBundle config = ResourceBundle.getBundle("email", Locale.SIMPLIFIED_CHINESE);
        mail_smtp_host = config.getString("mail.smtp.host");
        username = config.getString("username");
        password = config.getString("password");
        from = config.getString("from");
        fromname = config.getString("fromname");
        if (Constants.NEED_COMPOSE_ENCODE)
            fromname = UtilTools.encodeString(fromname);
        authenticator = config.getString("mail.smtp.auth");

        prp.setProperty("mail.smtp.host", mail_smtp_host);
        prp.setProperty("username", username);
        prp.setProperty("password", password);
        prp.setProperty("mail.smtp.auth", authenticator); }
private boolean SendEmailsTCB() {
	try {
		EmailBaseAuthenticator sa = new EmailBaseAuthenticator(username,password);
		Session session = Session.getInstance(prp, sa);
		//发邮件
		MimeMessage sendmessage = new MimeMessage(session);
		sendmessage.setFrom(new InternetAddress(from, fromname, "GBK"));
		// 分拆收件人
		StringTokenizer stk_to = new StringTokenizer(to, ";");
		int count_to = stk_to.countTokens();
		int i = 0;
		InternetAddress[] address_to = new InternetAddress[count_to];
		while (stk_to.hasMoreTokens()) {
			String email = stk_to.nextToken();
			address_to[i] = new InternetAddress(email, "", "GBK");
			i++;
		}
		sendmessage.addRecipients(Message.RecipientType.TO, address_to);
		// 分拆抄送人
		StringTokenizer stk_cc = new StringTokenizer(cc, ";");
		int count_cc = stk_cc.countTokens();
		int j = 0;
		InternetAddress[] address_cc = new InternetAddress[count_cc];
		while (stk_cc.hasMoreTokens()) {
			String email = stk_cc.nextToken();
			address_cc[j] = new InternetAddress(email, "", "GBK");
			j++;
		}
		sendmessage.addRecipients(Message.RecipientType.CC, address_cc);
		// 分拆密送人
		StringTokenizer stk_bcc = new StringTokenizer(bcc, ";");
		int count_bcc = stk_bcc.countTokens();
		int k = 0;
		InternetAddress[] address_bcc = new InternetAddress[count_bcc];
		while (stk_bcc.hasMoreTokens()) {
			String email = stk_bcc.nextToken();
			address_bcc[k] = new InternetAddress(email, "", "GBK");
			k++;
		}
		sendmessage.addRecipients(Message.RecipientType.BCC, address_bcc);
		if (Constants.NEED_COMPOSE_ENCODE)
			sendmessage.setSubject(UtilTools.encodeString(subject), "GBK");
		sendmessage.setSubject(subject, "GBK");
		sendmessage.setSentDate(new Date());
		sendmessage.setContent(body, "text/html; charset=GBK");
		Transport.send(sendmessage);
	} catch (AuthenticationFailedException afe) {
		afe.printStackTrace();
		return false;
	} catch (AddressException ae) {
		ae.printStackTrace();
		return false;
	} catch (javax.mail.MessagingException e) {
		e.printStackTrace();
		return false;
	} catch (java.io.UnsupportedEncodingException e) {
		e.printStackTrace();
		return false;
	} catch (Exception e) {
		e.printStackTrace();
		return false;
	}
	return true;
}

3、需要调的实现类

public class EmailBaseAuthenticator extends Authenticator {
    private String username;
    private String password;

  public EmailBaseAuthenticator(String username, String password) {
        this.username = username;
        this.password = password;
    }public PasswordAuthentication getPasswordAuthentication() {

        return new PasswordAuthentication(this.username, this.password);

}

}

4、使用mail.jar和commons-email-1.3.3-bin.zip轻松发送邮件

 

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.MultiPartEmail;
 
public class Test {
	public static void main(String[] args) throws Exception {

//	    SimpleEmail - This class is used to send basic text based emails.
//	    MultiPartEmail - This class is used to send multipart messages. This allows a text message with attachments either inline or attached.
//	    HtmlEmail - This class is used to send HTML formatted emails. It has all of the capabilities as MultiPartEmail allowing attachments to be easily added. It also supports embedded images.
//	    ImageHtmlEmail - This class is used to send HTML formatted emails with inline images. It has all of the capabilities as HtmlEmail but transform all image references to inline images.
//	    EmailAttachment - This is a simple container class to allow for easy handling of attachments. It is for use with instances of MultiPartEmail and HtmlEmail.

		MultiPartEmail  email = new MultiPartEmail();
		email.setHostName("smtp.qq.com");
		email.setSmtpPort(25);
		email.setAuthenticator(new DefaultAuthenticator("1*********", "a************"));
		email.setSSLOnConnect(true);
		email.setFrom("1************@qq.com");
		email.setSubject("TestMail测试邮箱");
		email.setMsg("This is a test mail ... :用纸-)");
		email.addTo("y*****@163.com");
		EmailAttachment emailAttachment = new EmailAttachment();
		emailAttachment.setPath("mail.jar");
		emailAttachment.setName("java邮件架包");
		email.attach(emailAttachment); 
		email.send();  
	}
}
