ubuntu下的代码格式化工具

indent -kr -i4 SimpleMail.java 可以用，但是太简单

astyle 这个工具不错

http://astyle.sourceforge.net/

astyle --style=java --style=allman -f SimpleMail.java

发送邮件的java代码！！亲测可以用

import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
 
import java.util.Properties;
 
public class SimpleMail
{
 
    private static final String SMTP_HOST_NAME = "smtp.host.com";
    private static final String SMTP_AUTH_USER = "no-replay@xxxx.com";
    private static final String SMTP_AUTH_PWD = "password";
 
    public static void main(String[]args) throws Exception
    {   
        new SimpleMail().test();
    }   
    public void test() throws Exception
    {   
        Properties props = new Properties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.host", SMTP_HOST_NAME);
        props.put("mail.smtp.auth", "true");
 
        Authenticator auth = new SMTPAuthenticator();
        Session mailSession = Session.getDefaultInstance(props, auth);
 
        // uncomment for debugging infos to stdout
        // mailSession.setDebug(true);
        Transport transport = mailSession.getTransport();
 
        MimeMessage message = new MimeMessage(mailSession);
        message.setContent("This is a test", "text/plain");
        message.setFrom(new InternetAddress("xxx.com"));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress("12354656@qq.com"));
 
        transport.connect();
        transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
        transport.close();
    }   
    private class SMTPAuthenticator extends javax.mail.Authenticator
    {   
        public PasswordAuthentication getPasswordAuthentication()
        {
            String username = SMTP_AUTH_USER;
            String password = SMTP_AUTH_PWD;
            return new PasswordAuthentication(username, password);
        }
