SSM框架发送邮件的问题！

回答 1 已采纳最近做项目SSM框架需要用发送邮件，以前没写过发送邮件，谁有这方面的思路或者例子不吝赐教，我的需求是从数据库找到该条数据，然后往该注册邮箱里面发送该条数据，下面是度娘出来的东西，不知道用啥，直接跑java application能直接运行到你所指定的邮箱，我数据库的值能抓出来然后不知道怎么往里面放了，不知道怎么写了，求大神指教一二 package me.reg.util; import java.util.Date; import java.util.Properties; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class MailUtil { public static String myEmailAccount = "test1@lb.com"; public static String myEmailPassword = "123456"; // 发件人邮箱的 SMTP 服务器地址, 必须准确, 不同邮件服务器地址不同, 一般(只是一般, 绝非绝对)格式为: smtp.xxx.com // 网易163邮箱的 SMTP 服务器地址为: smtp.163.com public static String myEmailSMTPHost = "127.0.0.1"; // 收件人邮箱（替换为自己知道的有效邮箱） public static String receiveMailAccount = "test2@lb.com"; public static void sendTo(String body, String receiveMailAccount) throws Exception { //只需要传入正文和目标地址即可 Properties props = new Properties(); // 参数配置 props.setProperty("mail.transport.protocol", "smtp"); // 使用的协议（JavaMail规范要求） props.setProperty("mail.smtp.host", myEmailSMTPHost); // 发件人的邮箱的 SMTP // 服务器地址 props.setProperty("mail.smtp.auth", "true"); // 需要请求认证 // PS: 某些邮箱服务器要求 SMTP 连接需要使用 SSL 安全认证 (为了提高安全性, 邮箱支持SSL连接, 也可以自己开启), // 如果无法连接邮件服务器, 仔细查看控制台打印的 log, 如果有有类似 “连接失败, 要求 SSL 安全连接” 等错误, // 打开下面 /* ... */ 之间的注释代码, 开启 SSL 安全连接。 /* * // SMTP 服务器的端口 (非 SSL 连接的端口一般默认为 25, 可以不添加, 如果开启了 SSL 连接, // * 需要改为对应邮箱的 SMTP 服务器的端口, 具体可查看对应邮箱服务的帮助, // QQ邮箱的SMTP(SLL)端口为465或587, * 其他邮箱自行去查看) final String smtpPort = "465"; * props.setProperty("mail.smtp.port", smtpPort); * props.setProperty("mail.smtp.socketFactory.class", * "javax.net.ssl.SSLSocketFactory"); * props.setProperty("mail.smtp.socketFactory.fallback", "false"); * props.setProperty("mail.smtp.socketFactory.port", smtpPort); */ // 2. 根据配置创建会话对象, 用于和邮件服务器交互 Session session = Session.getDefaultInstance(props); session.setDebug(false); // 设置为debug模式, 可以查看详细的发送 log // 4. 根据 Session 获取邮件传输对象 Transport transport = session.getTransport(); // 3. 创建一封邮件 MimeMessage message = createMimeMessage(session, myEmailAccount, receiveMailAccount, body); // 4. 根据 Session 获取邮件传输对象 transport = session.getTransport(); // 5. 使用邮箱账号和密码连接邮件服务器, 这里认证的邮箱必须与 message 中的发件人邮箱一致, 否则报错 // // PS_01: 成败的判断关键在此一句, 如果连接服务器失败, 都会在控制台输出相应失败原因的 log, // 仔细查看失败原因, 有些邮箱服务器会返回错误码或查看错误类型的链接, 根据给出的错误 // 类型到对应邮件服务器的帮助网站上查看具体失败原因。 // // PS_02: 连接失败的原因通常为以下几点, 仔细检查代码: // (1) 邮箱没有开启 SMTP 服务; // (2) 邮箱密码错误, 例如某些邮箱开启了独立密码; // (3) 邮箱服务器要求必须要使用 SSL 安全连接; // (4) 请求过于频繁或其他原因, 被邮件服务器拒绝服务; // (5) 如果以上几点都确定无误, 到邮件服务器网站查找帮助。 // // PS_03: 仔细看log, 认真看log, 看懂log, 错误原因都在log已说明。 transport.connect(myEmailAccount, myEmailPassword); // 6. 发送邮件, 发到所有的收件地址, message.getAllRecipients() // 获取到的是在创建邮件对象时添加的所有收件人, // 抄送人, 密送人 transport.sendMessage(message, message.getAllRecipients()); // 7. 关闭连接 transport.close(); } public static MimeMessage createMimeMessage(Session session, String sendMail, String receiveMail, String body) throws Exception { // 1. 创建一封邮件 MimeMessage message = new MimeMessage(session); // 2.
