package cn.itcast.utils;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import sun.misc.BASE64Encoder;
public class Base64Util
{
public static void main(String args[]) throws IOException
{
System.out.print("请输入用户名:");
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String userName = in.readLine();
System.out.print("请输入密码:");
String password = in.readLine();
BASE64Encoder encoder = new BASE64Encoder();
System.out.println("编码后的用户名为:"
+ encoder.encode(userName.getBytes()));
System.out.println("编码后的密码为:"
+ encoder.encode(password.getBytes()));
}
}编码后的密码为:MXFhejJ3c3g=
通过nslookup
set type=mx1. A记录：WEB服务器的IP指向（IP是固定的，怎么样都不变，域名是变化的）
A (Address) 记录是用来指定主机名（或域名）对应的IP地址记录。
2.MX记录（Mail Exchange）：邮件路由记录
这个大家都明白了吗？就是将你的域名中邮件服务器分开，将它设置到其它的IP去！
比如同样是 myweb.com ，如果你设置A记录是指向123.12.123.123，而MX记录你设置是指向222.22.222.222，那么你的DNS服务器接收到别人的邮件路 由请求时就将会将它的请求解释到222.22.222.222上去！而别人访问你的网页的时候仍然是访问123.12.123.123。
主要原因是：
javax.mail和javax.activation这两个包已经在javaEE5当中属于基础包了，就是JDK中自带了已经，但是里面的方法与现在外面的mail.jar和activation.jar有一些出入，所以初学者在直接copy别人代码的时候往往会出现上面的错误。
废话不多说下面是解决方法
进到
X:/Program Files/MyEclipse 6.5/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806/data/libraryset/EE_5
这个路径里,可以看到javaee.jar,用rar把这个文件打开,然后进到javax文件夹里,删除mail.jar和activation.jar(我的javaee.jar里，这两个东西是文件夹，总之删掉就OK，不过要注意备份一下)
删掉之后运行下面的代码，经行简单的修改以后就可以实现接收邮件的功能了！
2、附件名乱码 MimeUtility.encodeText
如 attachment.setFileName(MimeUtility.encodeText("因为爱情.mp3"));
@Test
public void demo() throws AddressException, MessagingException,
FileNotFoundException, IOException {
// 编写 嵌入图片 携带附件 邮件
// 包含附件的邮件
Properties props = new Properties();// 发送邮件、接收邮件
Session session = Session.getDefaultInstance(props);
// 编写嵌入图片的邮件
Message message = new MimeMessage(session);
// 所有邮件必须信息
message.setFrom(new InternetAddress("aaa@estore.com"));
message.setRecipient(RecipientType.TO, new InternetAddress(
"bbb@estore.com"));
message.setSubject("这是一个包含附件和嵌入图片的邮件");
// 编写邮件正文
MimeBodyPart content = new MimeBodyPart();
content.setContent("该邮件既有图片 又有附件！图片<img src='cid:mypic'/>",
"text/html;charset=utf-8");
MimeBodyPart pic = new MimeBodyPart();
DataHandler dh1 = new DataHandler(new FileDataSource("mm.jpg"));
pic.setDataHandler(dh1);
pic.setContentID("mypic");
MimeBodyPart attachment = new MimeBodyPart();
DataHandler dh2 = new DataHandler(new FileDataSource("love.mp3"));
attachment.setDataHandler(dh2);
attachment.setFileName(MimeUtility.encodeText("因为爱情.mp3"));
// 整合
MimeMultipart m1 = new MimeMultipart();
m1.addBodyPart(content);
m1.addBodyPart(pic);
m1.setSubType("related");
MimeBodyPart temp = new MimeBodyPart();
temp.setContent(m1);
// 继续整合
MimeMultipart m2 = new MimeMultipart();
m2.addBodyPart(temp);
m2.addBodyPart(attachment);
m2.setSubType("mixed");
message.setContent(m2);
message.writeTo(new FileOutputStream("c:\\测试用复杂邮件.eml"));
