javaMail的java邮件

在google code上有一个现成的javaMail的java邮件客户端，我们只需要调用其中的接口就可以了。下面放出使用javaMail的一个demo源代码。

1.自己封装一个邮件发送类MailSender。

public class MailSender extends Authenticator {

private String user;

private String password;

private Session session;

private String mailhost = "smtp.gmail.com";//默认用gmail发送

private Multipart messageMultipart;

private Properties properties;

static {

Security.addProvider(new JSSEProvider());

}

public MailSender(String user, String password) {

this.user = user;

this.password = password;

properties = new Properties();

properties.setProperty("mail.transport.protocol", "smtp");

properties.setProperty("mail.host", mailhost);

properties.put("mail.smtp.auth", "true");

properties.put("mail.smtp.port", "465");

properties.put("mail.smtp.socketFactory.port", "465");

properties.put("mail.smtp.socketFactory.class",

"javax.net.ssl.SSLSocketFactory");

properties.put("mail.smtp.socketFactory.fallback", "false");

properties.setProperty("mail.smtp.quitwait", "false");

session = Session.getDefaultInstance(properties, this);

messageMultipart=new MimeMultipart();

}

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(user, password);

}

public synchronized void sendMail(String subject, String body,

String sender, String recipients,String attachment) throws Exception {

MimeMessage message = new MimeMessage(session);

message.setSender(new InternetAddress(sender));//邮件发件人

message.setSubject(subject);//邮件主题

//设置邮件内容

BodyPart bodyPart=new MimeBodyPart();

bodyPart.setText(body);

messageMultipart.addBodyPart(bodyPart);

// message.setDataHandler(handler);

//设置邮件附件

if(attachment!=null){

DataSource dataSource=new FileDataSource(attachment);

DataHandler dataHandler=new DataHandler(dataSource);

bodyPart.setDataHandler(dataHandler);

bodyPart.setFileName(attachment.substring(attachment.lastIndexOf("/")+1));

}

message.setContent(messageMultipart);

if (recipients.indexOf(',') > 0)

//多个联系人

message.setRecipients(Message.RecipientType.TO,

InternetAddress.parse(recipients));

else

//单个联系人

message.setRecipient(Message.RecipientType.TO, new InternetAddress(

recipients));

Transport.send(message);

}

//继承DataSource设置字符编码

public class ByteArrayDataSource implements DataSource {

private byte[] data;

private String type;

public ByteArrayDataSource(byte[] data, String type) {

super();

this.data = data;

this.type = type;

}

public ByteArrayDataSource(byte[] data) {

super();

this.data = data;

}

public void setType(String type) {

this.type = type;

}

public String getContentType() {

if (type == null)

return "application/octet-stream";

else

return type;

}

public InputStream getInputStream() throws IOException {

return new ByteArrayInputStream(data);

}

public String getName() {

return "ByteArrayDataSource";

}

public OutputStream getOutputStream() throws IOException {

throw new IOException("Not Supported");

}

public PrintWriter getLogWriter() throws SQLException {

// TODO Auto-generated method stub

return null;

}

public int getLoginTimeout() throws SQLException {

// TODO Auto-generated method stub

return 0;

}

public void setLogWriter(PrintWriter out) throws SQLException {

// TODO Auto-generated method stub

}

public void setLoginTimeout(int seconds) throws SQLException {

// TODO Auto-generated method stub

}

public boolean isWrapperFor(Class<?> arg0) throws SQLException {

// TODO Auto-generated method stub

return false;

}

public <T> T unwrap(Class<T> arg0) throws SQLException {

// TODO Auto-generated method stub

return null;

}

public Connection getConnection() throws SQLException {

// TODO Auto-generated method stub

return null;

}

public Connection getConnection(String theUsername, String thePassword)

throws SQLException {

// TODO Auto-generated method stub

return null;

}

}

public String getMailhost() {

return mailhost;

}

public void setMailhost(String mailhost) {

this.mailhost = mailhost;

properties.setProperty("mail.host", this.mailhost);

}

}

2.JSSE将帮助处理TLS和SSL业务

public class JSSEProvider extends Provider {

public JSSEProvider() {

super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");

AccessController.doPrivileged(new java.security.PrivilegedAction<Void>() {

public Void run() {

put("SSLContext.TLS",

"org.apache.harmony.xnet.provider.jsse.SSLContextImpl");

put("Alg.Alias.SSLContext.TLSv1", "TLS");

put("KeyManagerFactory.X509",

"org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl");

put("TrustManagerFactory.X509",

"org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl");

return null;

}

});

}

}

3.主activity调用邮件发送类

public class MainActivity extends Activity {

private Button sendButton = null;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

sendButton = (Button) this.findViewById(R.id.send_btn);

sendButton.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

// TODO Auto-generated method stub

SenderRunnable senderRunnable = new SenderRunnable(

"xxxxxxx@163.com", "xxxxxxxx");

senderRunnable.setMail("this is the test subject",

"this is the test body", "xxxxxxxxx@gmail.com","/mnt/sdcard/test.txt");

new Thread(senderRunnable).start();

}

});

}

public boolean onCreateOptionsMenu(Menu menu) {

}

//android3.2不允许主线程通信

class SenderRunnable implements Runnable {

private String user;

private String password;

private String subject;

private String body;

private String receiver;

private MailSender sender;

private String attachment;

public SenderRunnable(String user, String password) {

this.user = user;

this.password = password;

sender = new MailSender(user, password);

String mailhost=user.substring(user.lastIndexOf("@")+1, user.lastIndexOf("."));

if(!mailhost.equals("gmail")){

mailhost="smtp."+mailhost+".com";

Log.i("hello", mailhost);

sender.setMailhost(mailhost);

}

}

public void setMail(String subject, String body, String receiver,String attachment) {

this.subject = subject;

this.body = body;

this.receiver = receiver;

this.attachment=attachment;

}

public void run() {

// TODO Auto-generated method stub

try {

sender.sendMail(subject, body, user, receiver,attachment);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}
