javaWEB邮件测试

新建一个工具类:

Mail.java

该类的主要关键点是:1、设置系统属性。也就是你是用什么协议来进行邮件发送的,邮件协议有很多在种,比如impt,smpt,prop等协议,

我现在测试用的是smpt协议,smpt协议里也分为很多种,以为有不同的邮箱QQ,126,新浪等,所以就有不同的smpt系统属性了(注:这些

都可以再网上查到),我用的协议是smpt.qq.com,通过property将它存到map集合里面:props.put("host","smpt.qq.com")

2、准备获取邮件回话对象,通过mail.jar包中Session.getDefaultInstance()来获取回话。

3、准备创建MIME邮件对象,jar包自带的MimeMessage(session)方法

4、设置smtp身份认证:props.put("mail.smtp.auth", "true");

5、定义邮件主题:mimeMsg.setSubject(mailSubject);6、

6、定义邮件内容:bp.setContent("" + mailBody, "text/html;charset=GBK");

7、设置发信人:mimeMsg.setFrom(new InternetAddress(from));

8、定义收信人:mimeMsg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));

9、定义抄送人:mimeMsg.setRecipients(Message.RecipientType.CC, (Address[]) InternetAddress .parse(copyto));

以下是源码:

 以上代码,经过测试,可以运行成功。注意:

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
当出现以上错误时,恭喜您已经离接收邮件不远了,否则请您解决好所有的异常后再来看这个帖子。

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)
