版本一：JavaMail的一个工具类
package ${enclosing_package}; import java.security.GeneralSecurityException; import java.util.Properties; import javax.mail.Authenticator; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMessage.RecipientType; import com.sun.mail.util.MailSSLSocketFactory; public class ${primary_type_name} { //email:邮件发给谁 subject:主题 emailMsg：邮件的内容 public static void sendMail(String email, String subject, String emailMsg) throws AddressException, MessagingException { // 1.创建一个程序与邮件服务器会话对象 Session Properties props = new Properties(); props.setProperty("mail.transport.protocol", "SMTP");//发邮件的协议 props.setProperty("mail.host", "smtp.126.com");//发送邮件的服务器地址 props.setProperty("mail.smtp.auth", "true");// 指定验证为true //开启SSL加密 ,QQ邮箱必须开启ssl加密才可以。 MailSSLSocketFactory sf = null; try { sf = new MailSSLSocketFactory(); } catch (GeneralSecurityException e) { e.printStackTrace(); } sf.setTrustAllHosts(true); props.put("mail.smtp.ssl.enable", "true"); props.put("mail.smtp.ssl.socketFactory", sf); // 创建验证器 Authenticator auth = new Authenticator() { public PasswordAuthentication getPasswordAuthentication() { //发邮件的账号的验证 12345为授权码，并非密码。tom可以不用加上@126.com return new PasswordAuthentication("tom", "12345"); } }; //这个是邮箱服务器的session 和之前学的session不是同一个session Session session = Session.getInstance(props, auth); // 2.创建一个Message，它相当于是邮件内容 Message message = new MimeMessage(session); message.setFrom(new InternetAddress("tom@126.com")); // 设置发送者 message.setRecipient(RecipientType.TO, new InternetAddress(email)); // 设置发送方式与接收者 message.setSubject(subject);//邮件的主题 message.setContent(emailMsg, "text/html;charset=utf-8"); // 3.创建 Transport用于将邮件发送 Transport.send(message); } }
一个JavaMail的例子
package com.test.jobs; import java.security.GeneralSecurityException; import java.util.List; import java.util.Properties; import javax.annotation.Resource; import javax.mail.Authenticator; import javax.mail.Message.RecipientType; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import com.sun.mail.util.MailSSLSocketFactory; import com.test.bos.dao.IWorkbillDao; import com.test.bos.domain.Workbill; /** * 发送邮件的作业 * @author zhaoqx * */ public class MailJob { @Resource private IWorkbillDao workbillDao;
//属性可以通过页面提交获得，也可以通过spring的配置文件注入 private String username; //发件人邮箱 private String password; //发邮件的账号的验证 12345为授权码，并非密码 private String smtpServer;//发送邮件的服务器地址 private String protocol;//发送右键的协议 public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getSmtpServer() { return smtpServer; } public void setSmtpServer(String smtpServer) { this.smtpServer = smtpServer; } public String getProtocol() { return protocol; } public void setProtocol(String protocol) { this.protocol = protocol; } public void execute() { System.out.println("要发邮件了。。。"); try { //查询工单类型为新单的所有工单 List<Workbill> list = workbillDao.findAll(); if(null != list && list.size() > 0){ // 创建一个程序与邮件服务器会话对象 Session final Properties mailProps = new Properties(); mailProps.put("mail.transport.protocol", this.getProtocol()); //发送邮件的协议 mailProps.put("mail.host", this.getSmtpServer()); //发送邮件的服务器地址 mailProps.put("mail.smtp.auth", "true"); // 指定验证为true mailProps.put("mail.username", this.getUsername()); mailProps.put("mail.password", this.getPassword()); //开启SSL加密 ,QQ邮箱必须开启ssl加密才可以。 MailSSLSocketFactory sf = null; try { sf = new MailSSLSocketFactory(); } catch (GeneralSecurityException e) { e.printStackTrace(); } sf.setTrustAllHosts(true); mailProps.put("mail.smtp.ssl.enable", "true"); mailProps.put("mail.smtp.ssl.socketFactory", sf); // 构建授权信息，用于进行SMTP进行身份验证 Authenticator authenticator = new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { // 用户名、密码 String userName = mailProps.getProperty("mail.username"); String password = mailProps.getProperty("mail.password"); return new PasswordAuthentication(userName, password); } }; // 使用环境属性和授权信息，创建邮件会话 Session mailSession = Session.getInstance(mailProps, authenticator); for(Workbill workbill : list){ // 创建邮件消息 MimeMessage message = new MimeMessage(mailSession); // 设置发件人 InternetAddress from = new InternetAddress(mailProps.getProperty("mail.username")); message.setFrom(from); // 设置收件人 InternetAddress to = new InternetAddress("151956669@qq.com"); //设置发送方式与接收者 message.setRecipient(RecipientType.TO, to); // 设置邮件标题 message.setSubject("激活邮件"); // 设置邮件的内容体 message.setContent(workbill.toString(), "text/html;charset=UTF-8"); // 发送邮件 Transport.send(message); } } } catch (Exception ex) { ex.printStackTrace(); } } }
spring的注入方式如下：
<bean name="myJob" class="com.test.jobs.MailJob"> <property name="username" value="tom@126.com"/> <property name="password" value="123456"/> <property name="smtpServer" value="smtp.126.com"/> <property name="protocol" value="SMTP"/> </bean>
