mail.jar下载 349k
<!-- 01-22 更新 -->
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
如果你用myEclipse进行开发的话,运行时可能会出现以下的错误:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
原因是jar包版本不统一,解决方法如下:
删除Java EE 5 Libraries/javaee.jar/mail里的包有东西.
具体方法如下:
用rar打开X:C:\Program Files\MyEclipse 6.5\myeclipse\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806\data\libraryset\EE_5\javaee.jar
,然后删除mail,一切就ok了.

最近在博友spark博客上发现一篇关于使用commons email 发邮件的帖子,很感兴趣,因为以前还真没做过这方面的功能。进去看了看,然后又到Apache官网上找了UserGuide看了看,居然发现发邮件这么简单~~
本文完全参考于Apache的用户指南,有价值的地方(用户指南没有的)为 邮件乱码问题,和主机方为Google邮箱问题处理,如果这些都知道,还是看Apache的userguide.html,比我的简明多了
参考文档:http://commons.apache.org/email/userguide.html
运行程序截图:
真是战况喜人啊,第一次运行居然全部ok。
可点击进去却发现邮件中设置了中文的地方都出现了乱码
简单邮件测试中消息“你好,郵件測試,看到這,說明已經成功了”出现为?????
但到带本地附件邮件中:附件名称为中文,没有显示,显示为 No name 2.jpg,但是消息 “你好,郵件測試,看到這,說明已經成功了”却又正常显示出来,纠结!!
Google一下,发现已经有很多帖子来解决它,随便挑了个,就ok了,就是给它设置编码
//设置编码
email.setCharset("UTF-8");
附件Attachment没有setCharset方法,但可以用
MimeUtility.encodeText(String str)来转换
简单邮件测试:
带本地附件的邮件
带网络附件的邮件
HTML EMAIL
需要jar包 mail.jar 和commons-email-1.2.jar
代码
