在發送帶有附件的郵件中，遇到了附件中文名亂碼的問題，現已解決。只談解決方法，具體原理解析請參考文章底部連接。html

主要遇到的問題有兩個：java

中文亂碼
中文過長致使亂碼(這個通常是在超過60個字符時會出現的)

解決方案：apache

1.解決第一個的問題是用MimeUtility.encodeText()進行解碼this

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

2.解決第二個問題設置了一個系統屬性(該屬性最好是在聲明對象前設置，否則有可能無效的).net

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

代碼示例：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;
