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 stubthis.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 hostprops.put("mail.smtp.host", host);//set SMTP authorizationprops.put("mail.smtp.auth", "true");//get the mail sessionMyAuthenticator auth = new MyAuthenticator(name,password);session = Session.getDefaultInstance(props,auth);//create MIME mail objectmessage = 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 blocke.printStackTrace();} catch (MessagingException e) {// TODO Auto-generated catch blocke.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 blocke.printStackTrace();} catch (MessagingException e) {// TODO Auto-generated catch blocke.printStackTrace();}}/** * set mail subject * @param subject */public void setSubject(String subject){try {message.setSubject(subject);} catch (MessagingException e) {// TODO Auto-generated catch blocke.printStackTrace();}}/** * set mail text * @param text */public void setText(String text){try {message.setText(text);} catch (MessagingException e) {// TODO Auto-generated catch blocke.printStackTrace();}}/** * send mail * @return */public boolean send(){try{//create SMTP sender objectTransport transport = session.getTransport("smtp");//get the connection with servertransport.connect((String) props.get("mail.smtp.host"),name,password);//send the mail via servertransport.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 stubString from = "[e-mail]";String to = "[e-mail]";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!");}}}
