通过commons-email发送邮件
首先，去http://commons.apache.org/email/把commons-email-1.2-bin.zip下载下来，然后把其中的commons-email-1.2.jar包导入项目中。
commons-email-1.2.jar很小，只有32k，也就是9个类而已，却能省不少事。
commons-email-1.2.jar提供了如下9个类：ByteArrayDataSource、DefaultAuthenticator、Email、EmailAttachment、EmailException、EmailUtils、HtmlEmail、MultiPartEmail、SimpleEmail。
在http://commons.apache.org/email/userguide.html有commons-email的使用示例。
1、SimpleEmail
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.SimpleEmail;
public class MailTo {
public static void main(String[] args) {
try {
//发送简单邮件
SimpleEmail email = new SimpleEmail();
email.setHostName("smtp.sina.com");
//需要邮件发送服务器的用户名、密码验证
email.setAuthentication("[email protected]", "XXX");
email.addTo("[email protected]", "Eric");
email.setFrom("[email protected]", "Michael");
email.setCharset("UTF-8");
email.setSubject("测试邮件");
email.setMsg("这是一封测试邮件");
email.send();
} catch (EmailException e) {
e.printStackTrace();
}
}
}
2、HtmlEmail
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
public class MailTo {
public static void main(String[] args) {
try {
HtmlEmail email = new HtmlEmail();
email.setHostName("smtp.sina.com");
email.setAuthentication("[email protected]", "XXX");
email.addTo("[email protected]", "Eric");
email.setFrom("[email protected]", "Michael");
email.setCharset("UTF-8");
email.setSubject("测试邮件");
URL url = new URL("http://www.apache.org/images/asf_logo_wide.gif");
String cid = email.embed(url, "Apache logo");
email.setHtmlMsg("<html>The apache logo - <img src=\"cid:" + cid
+ "\"></html>");
email.setTextMsg("Your email client does not support HTML messages");
email.send();
} catch (EmailException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
3、EmailAttachment
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.MultiPartEmail;
public class MailTo {
public static void main(String[] args) {
try {
// Create the attachment
EmailAttachment attachment = new EmailAttachment();
attachment.setURL(new URL(
"http://www.apache.org/images/asf_logo_wide.gif"));
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription("Apache logo");
attachment.setName("Apache logo");
// Create the email message
MultiPartEmail email = new MultiPartEmail();
email.setHostName("smtp.sina.com");
email.setAuthentication("[email protected]", "XXX");
email.addTo("[email protected]", "Eric");
email.setFrom("[email protected]", "Michael");
email.setCharset("UTF-8");
email.setSubject("测试邮件");
email.setMsg("这是一封测试邮件");
// add the attachment
email.attach(attachment);
email.send();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (EmailException e) {
e.printStackTrace();
}
}
}
