idea建立maven项目

只需要三个文件

pom.xml

Test.java

package javamail;

public class Test {

    public static void main(String[] args) {

        MailOperation operation = new MailOperation();
        String user = "";  //需要你的163邮箱账户
        String password = ""; //163授权码，不是登录密码
        String host = "smtp.163.com";
        String from = ""; //发件人
        String to = "";// 收件人
        String subject = "邮件主题";
        //邮箱内容
        StringBuffer sb = new StringBuffer();
        String yzm = "12345";
        sb.append("<!DOCTYPE>"+"<div bgcolor='#f1fcfa'   style='border:1px solid #d9f4ee; font-size:14px; line-height:22px; color:#005aa0;padding-left:1px;padding-top:5px;   padding-bottom:5px;'><span style='font-weight:bold;'>温馨提示：</span>"
                + "<div style='width:950px;font-family:arial;'>欢迎使用，您的注册码为：<br/><h2 style='color:green'>"+yzm+"</h2><br/>本邮件由系统自动发出，请勿回复。<br/>感谢您的使用。<br/></div>"
                +"</div>");
        try {
            String res = operation.sendMail(user, password, host, from, to,
                    subject, sb.toString());
            System.out.println(res);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

运行main，会有调试信息输出
