在发送带有附件的邮件中，遇到了附件中文名乱码的问题，现已解决。只谈解决方法，具体原理解析请参考文章底部连接。html

主要遇到的问题有两个：java

中文乱码
中文过长致使乱码(这个通常是在超过60个字符时会出现的)

解决方案：apache

1.解决第一个的问题是用MimeUtility.encodeText()进行解码this

attach.setName(MimeUtility.encodeText(f.getName()));

2.解决第二个问题设置了一个系统属性(该属性最好是在声明对象前设置，否则有可能无效的).net

System.getProperties().setProperty("mail.mime.splitlongparameters", "false");

代码示例：code

import org.apache.commons.collections.CollectionUtils;
import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.HtmlEmail;

import javax.mail.internet.MimeUtility;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
