J2EE项目里有用到JavaMail，研究了下。下面是参考资料和我的JavaMail：
package mail;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class Mail {
private Properties props;//系统属性，可以get和put属性名值对。
private Session session;//根据系统属性设置会话
private Message msg;//MimeMessage为其子类
//管理员SMTP服务器信息
private String host;
private String username;
private String password;
private String from;
public Mail(String host, String username, String password, String from) {
props = System.getProperties();
//props.put(“mail.smtp.host”, “smtp.jspinsider.com”);
props.put(“mail.smtp.host”, host);
props.put(“mail.smtp.auth”, “true”);
session = Session.getDefaultInstance(props);
msg = new MimeMessage(session);
this.host = host;
this.username = username;
this.password = password;
this.from = from;
}
public void send(String to) throws MessagingException {
msg.setFrom(new InternetAddress(from));
msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setSubject(“测试”);
msg.setText(“测试”);
Transport transport = session.getTransport(“smtp”);
transport.connect((String)props.get(“mail.smtp.host”), username, password);
transport.sendMessage(msg, msg.getRecipients(Message.RecipientType.TO));
transport.close();
//Transport.send(msg);
}
}
