java利用JavaMail实现邮件功能

 

Mailbox.java: 表示邮箱的一些信息

package common; public class Mailbox { private String host; private String name; private String password; private String from; private String to; private String subject; private String content; /** * * @param host * @param name * @param password * @param mailInfo */ public Mailbox(String host, String name, String password,MailInfo mailInfo) { // TODO Auto-generated constructor stub this.host = host; this.name = name; this.password = password; this.from = mailInfo.getFrom(); this.to = mailInfo.getTo(); this.subject = mailInfo.getSubject(); this.content = mailInfo.getContent(); } /** * * @return */ public boolean sendTextMail(){ TextMail textMail = new TextMail(host,name,password); textMail.setFrom(from); textMail.setText(content); textMail.setTo(to); textMail.setSubject(subject); return textMail.send(); } }

 

MailInfo.java: 邮件的一些信息:from,to,suject,content

package common; public class MailInfo { private String from; private String to; private String subject; private String content; /** * * @param from * @param to * @param subject * @param content */ public MailInfo(String from, String to, String subject, String content){ this.from = from; this.to = to; this.subject = subject; this.content = content; } public String getFrom() { return from; } public void setFrom(String from) { this.from = from; } public String getTo() { return to; } public void setTo(String to) { this.to = to; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } }

 

TextMail.java:对要发送的邮件进行初始化

package common; import java.util.Properties; import javax.mail.BodyPart; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.NoSuchProviderException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; /** * function: Send a mail to the specific address * @author JAY * */ public class TextMail { private MimeMessage message; private Properties props; private Session session; private String name = ""; private String password = ""; /** * complete the initialization * @param host * @param name * @param password */ public TextMail(String host, String name, String password){ this.name = name; this.password = password; props = System.getProperties(); //set the SMTP host props.put("mail.smtp.host", host); //set SMTP authorization props.put("mail.smtp.auth", "true"); //get the mail session MyAuthenticator auth = new MyAuthenticator(name,password); session = Session.getDefaultInstance(props,auth); //create MIME mail object message = new MimeMessage(session); } /** * set mail sender * @param from */ public void setFrom(String from){ try { message.setFrom(new InternetAddress(from)); } catch (AddressException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (MessagingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } /** * set mail recipient * @param to */ public void setTo(String to){ try { message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to)); } catch (AddressException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (MessagingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } /** * set mail subject * @param subject */ public void setSubject(String subject){ try { message.setSubject(subject); } catch (MessagingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } /** * set mail text * @param text */ public void setText(String text){ try { message.setText(text); } catch (MessagingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } /** * send mail * @return */ public boolean send(){ try{ //create SMTP sender object Transport transport = session.getTransport("smtp"); //get the connection with server transport.connect((String) props.get("mail.smtp.host"),name,password); //send the mail via server transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO)); transport.close(); return true; }catch(NoSuchProviderException e){ e.printStackTrace(); return false; }catch (MessagingException e){ e.printStackTrace(); return false; } } }

 

MyAuthenticator.java

 

package common; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; public class MyAuthenticator extends Authenticator{ String name; String password; /** * * @param name * @param password */ public MyAuthenticator(String name, String password){ this.name = name; this.password = password; getPasswordAuthentication(); } protected PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(name,password); } }

 

Main.java:测试代码

package common; import java.util.*; public class Main { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub String from = "test@sina.com"; String to = "test@163.com"; String subject = "test"; String content = "hello,world!"; String host = "smtp.sina.com"; String name = "test"; String password = "pass"; /* Scanner scan = new Scanner(System.in); System.out.println("Please select your emailbox:"); System.out.println("mailbox host:"); host = scan.next(); System.out.println("mailbox name:"); name = scan.next(); System.out.println("mailbox password:"); password = scan.next(); System.out.println("send from:"); from = scan.next(); System.out.println("send to:"); to = scan.next(); System.out.println("subject:"); subject = scan.next(); System.out.println("text:"); text = scan.next();*/ MailInfo mailInfo = new MailInfo(from,to,subject,content); Mailbox mailBox = new Mailbox(host,name,password,mailInfo); if(mailBox.sendTextMail()){ System.out.println("Mail send successfully!"); } else{ System.out.println("Mail send failed!"); } } }
