package cn.bdqn;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;public class MailTest {public static void main(String[] args){ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");try{MailWithAttachment mailWithAttach = (MailWithAttachment)context.getBean("mailWithAttachment");mailWithAttach.send();}catch(Exception e){System.out.print(e.toString());}}
}    

package cn.bdqn;import java.io.IOException;import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;import org.springframework.core.io.ClassPathResource;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;public class MailWithAttachment {private JavaMailSender mailSender; //必须使用 JavaMailSenderpublic void setMailSender(JavaMailSender mailSender) {this.mailSender = mailSender;}public void send() throws MessagingException,IOException{MimeMessage mimeMessage = mailSender.createMimeMessage();MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "UTF-8");helper.setFrom("wxk@mail.com");helper.setTo("wj@mail.com");helper.setSubject("等待是种执着");helper.setText("青鸟的岁月似流年，又有多少青春如风逝去，不要让这座城市只留下无尽的回忆，却没有留下我们一起走过的青春，" +"青春不是生命的一瞬，而是一种自然的心境！");//添加附件1ClassPathResource file1 = new ClassPathResource("/cn/bdqn/attachfiles/QQ图片20161214191111.jpg");helper.addAttachment(file1.getFilename(), file1.getFile());//添加附件2：附件的文件名为中文时，需要对文件名进行编码转换，解决乱码问题ClassPathResource file2 = new ClassPathResource("/cn/bdqn/attachfiles/附件测试文件.doc");helper.addAttachment(MimeUtility.encodeWord(file2.getFilename()),file2.getFile());mailSender.send(mimeMessage);}
}

上传邮件成功

2.使用Spring发送简单邮件

大配置和log4j还要架包同上省略

package cn.bdqn;import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;public class Mail {private MailSender mailSender;public void setMailSender(MailSender mailSender) {this.mailSender = mailSender;}public void send(){SimpleMailMessage message = new SimpleMailMessage();message.setFrom("wxk@mail.com");message.setTo("wj@mail.com");message.setSubject("会议通知fsb发布");message.setText("jerry你好！请于明天下午16:00 准时到B01会议室召开技术讨论会。");mailSender.send(message);}
}

package cn.bdqn;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;public class MailTest {public static void main(String[] args){ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");/*测试简单邮件*/Mail mail = (Mail)context.getBean("mail");mail.send();}
}    

3.使用Spring邮件服务和FreeMarker模板技术发送邮件

大配置和log4j还要架包同上省略

package cn.bdqn.pojo;public class Mail {private String to;private String subject;private String content;public String getTo() {return to;}public void setTo(String to) {this.to = to;}public String getSubject() {return subject;}public void setSubject(String subject) {this.subject = subject;}public String getContent() {return content;}public void setContent(String content) {this.content = content;}}

package cn.bdqn.service;import cn.bdqn.pojo.Mail;public class LeaveService {private MailService mailService;public void setMailService(MailService mailService) {this.mailService = mailService;}public void updateLeave(){//省略审批请假申请//查询数据库获取相关信息String approver = "张来";Mail mail = new Mail();mail.setTo("wj@mail.com");mail.setSubject("请假流程确认邮件");StringBuffer sb = new StringBuffer();sb.append("<html><head>");sb.append("<meta http-equiv=\"content-type\" content=\"text/html;charset=utf-8\">");sb.append("<head><body>");sb.append("<font color='blue' size='4' face='Arial'>");sb.append("OA系统温馨提示：</font><br/><br/>");sb.append("&nbsp;&nbsp;&nbsp;&nbsp;");sb.append("在OA系统中，您提交的“请假流程” "+ approver +" 已经审批完成，点击如下链接可登陆系统查看流程，谢谢。" +"如果登录时忘记密码，可以在网站登录页找回。<br/>");sb.append("<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;<a href='http://www.jboa.com'>http://www.jboa.com</a>");sb.append("<br/><br/>&nbsp;&nbsp;&nbsp;&nbsp;-----本邮件为系统自动发出，请勿回复-----");mail.setContent(sb.toString());try{mailService.send(mail);}catch(Exception e){e.printStackTrace();}}}

package cn.bdqn.service;import java.io.IOException;import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;import cn.bdqn.pojo.Mail;public class MailService {private JavaMailSender mailSender; //必须使用 JavaMailSenderpublic void setMailSender(JavaMailSender mailSender) {this.mailSender = mailSender;}public void send(Mail mail) throws MessagingException,IOException{MimeMessage mimeMessage = mailSender.createMimeMessage();MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "UTF-8");helper.setFrom("wxk@mail.com");helper.setTo(mail.getTo());helper.setSubject(mail.getSubject());helper.setText(mail.getContent(),true);mailSender.send(mimeMessage);System.out.print("发送完成！");}
}

package cn.bdqn;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.bdqn.service.LeaveService;public class MailTest {public static void main(String[] args){ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");LeaveService service = (LeaveService)context.getBean("leaveService");service.updateLeave();}
}    

4.最简单的站内传送Email上传，不需要大配置、log4j、架包

package cn.happy.mailjames;import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;public class EmailAuthenticator extends Authenticator {private String username;   private String userpass;public void setUsername(String username) {this.username = username;}public void setUserpass(String userpass) {this.userpass = userpass;}public EmailAuthenticator() {}public EmailAuthenticator(String username, String userpass) {this.username = username;this.userpass = userpass;}public PasswordAuthentication getPasswordAuthentication(){return new PasswordAuthentication(username,userpass);}}

package cn.happy.mailjames;import java.util.Date;
import java.util.Properties;import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;public class Mail {private String mailServer,from,to,mailSubject,mailContent;private String username,password;public Mail(){//设置邮件信息//进行认证登录的用户名username="wxk@mail.com";//认证密码password="wxk";//认证的邮箱对应的邮件服务器mailServer="192.168.8.71";//发件人信息from="wxk";//收件人信息to="wj@mail.com";//邮件标题mailSubject="记录成长的每一个脚印，写下漫长的程序人生";//邮件内容mailContent="这是一封测试邮件！如有雷同，纯属不可能";}//设置邮件服务器@SuppressWarnings("static-access")
public  void send(){Properties prop=System.getProperties();//指定邮件serverprop.put("mail.smtp.host", mailServer);//是否开启认证prop.put("mail.smtp.auth", "true");//smtp协议的prop.put("mail.smtp.port", "25");//产生Session服务EmailAuthenticator mailauth=new EmailAuthenticator(username, password);Session mailSession=Session.getInstance(prop,(Authenticator)mailauth);try {//封装Message对象Message message=new MimeMessage(mailSession);message.setFrom(new InternetAddress(from)); //发件人message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));//收件人
           message.setSubject(mailSubject);//设置内容(设置字符集处理乱码问题)message.setContent(mailContent,"text/html;charset=gbk");message.setSentDate(new Date());//创建Transport实例，发送邮件Transport tran=mailSession.getTransport("smtp");tran.send(message,message.getAllRecipients());tran.close();} catch (Exception e) {e.printStackTrace();}}
}

package cn.happy.mailjames;public class Test {public static void main(String[] args) {Mail mail=new Mail();mail.send();System.out.println("success!");}}
