java email发送（附件中文的处理）

这里使用的是commons-email-1.3.2.jar进行的开发，自认为这是简单的邮件发送。
package com.yt.base.common; 

import java.io.UnsupportedEncodingException; 

import javax.mail.internet.MimeUtility; 

import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail; 

public class email { 

public static void main(String[] args) {
// TODO Auto-generated method stub
try {
HtmlEmail textemail = new HtmlEmail();
textemail.setHostName("smtp.163.com");//smtp邮箱服务器的地址
textemail.setSmtpPort(25);//smtp的端口号
textemail.setAuthenticator(new DefaultAuthenticator("xxx@163.com", "soiladmin"));//发送放的用户名和密码
textemail.setSSLOnConnect(false);
textemail.setFrom("xxx@163.com");//发送人
textemail.setSubject("标题");//发送标题 

String info = "aaaaaaaaaaaa";
textemail.setHtmlMsg(info);//发送邮箱内容
textemail.addTo("2xx@qq.com");//给什么人（用户）发送的邮箱地址 

//email附件发送开始
EmailAttachment attach = new EmailAttachment();
String fileN="D:\\msj.dox";
attach.setPath(fileN);
attach.setDisposition(EmailAttachment.ATTACHMENT);
try {
attach.setName(MimeUtility.encodeText(fileN));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
textemail.attach(attach);
//email附件发送结束
String aa= textemail.send();
} catch (EmailException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
