JavaMail

注意：须要引入activation.jar

  cos.jar

    mail.jar，

而且删除掉j2ee中的反复jar包（我的路径是D:myeclipse10For32Commonpluginscom.genuitec.eclipse.j2eedt.core_10.0.0.me201110301321datalibrarysetEE_5javaee.jar），用winrar打开javaee.jar，删除掉activation和mail两个包就OK了

在SimpleMailSender中能够改动发送者的名称

// 设置邮件消息的发送者

      //设置自己定义发件人昵称
    	String nick="";

      mailMessage.setFrom(new InternetAddress(nick+"<"+from+">"));
