下载1 封装好的java邮件包,代码调用示例 public static void main(String[] args) throws Exception {

FinderSendMail sendMail;

MailInfo mailInfo =new MailInfo();

mailInfo.setTitle("test title");

mailInfo.setFrom("xxx@163.com");

mailInfo.setHost("smtp.163.com");

mailInfo.setTo("xxx@gmail.com");

mailInfo.setUsername("xxx@163.com");

mailInfo.setPassword("xxx");

//mailInfo.setContentType("text/html");

mailInfo.setContent("welcome to 技术社区");

sendMail=new FinderSendMail(mailInfo);

sendMail.send();

} 就这么简单调用，就发出去了， 依赖包 activition.jar,mail.jar, log4j.jar 如果你放在有JAVAEE.JAR 环境下 运行 会有一下错误问题 首次运行你可能会遇到以下的错误，所以note.txt文件就用来提供遇到的错误以及对应的解决方案 note.txt java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
