1、spring配置文件(src/applicationContext.xml ):
<bean id="mailSender"class="org.springframework.mail.javamail.JavaMailSenderImpl"><property name="host" value="222.173.82.207"></property><property name="javaMailProperties"><props><prop key="mail.smtp.auth">true</prop><prop key="mail.smtp.timeout">25000</prop></props></property><property name="username" value="tiandeqing@ecode.net.cn" /><property name="password" value="密码" /></bean><bean id="freeMarker"class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"><property name="templateLoaderPath" value="classpath:mail" /><!--指定模板文件目录--><property name="freemarkerSettings"><!-- 设置FreeMarker环境属性--><props><prop key="template_update_delay">1800</prop><!--刷新模板的周期,单位为秒--><prop key="default_encoding">UTF-8</prop><!--模板的编码格式 --><prop key="locale">zh_CN</prop><!-- 本地化设置--></props></property></bean>
2、Java代码:
给指定的单个用户发送普通文本邮件:SpringMail.java
package aaa;import java.io.StringWriter;import java.util.HashMap;import java.util.Map;import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;import org.springframework.mail.SimpleMailMessage;import org.springframework.mail.javamail.JavaMailSender;import freemarker.template.Configuration;import freemarker.template.Template;public class SpringMail {private Configuration cfg = new Configuration();public static void main(String[] args) throws Exception {ApplicationContext ctx = new FileSystemXmlApplicationContext("src/applicationContext.xml");JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");SpringMail springMail = new SpringMail();springMail.sendMail(sender);}private void sendMail(JavaMailSender sender) throws Exception {SimpleMailMessage mail = new SimpleMailMessage();mail.setTo("tiandeqing@ecode.net.cn"); //接收人mail.setFrom("tiandeqing@ecode.net.cn"); //发送人mail.setSubject("test by amigo");//嵌入ftl模版cfg.setClassForTemplateLoading(getClass(), "/mail");Map root = new HashMap();root.put("username", "sucre"); //模板变量Template t = cfg.getTemplate("notify-mail.ftl");StringWriter writer = new StringWriter();t.process(root, writer);//把模版内容写入邮件中mail.setText(writer.toString());sender.send(mail);System.out.println("邮件发送成功!");}}
给指定的多个用户发送含有附件的html邮件,SpringMail_Batch_Attach_HTML.java
package aaa;import java.io.File;import java.io.StringWriter;import java.io.UnsupportedEncodingException;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeUtility;import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;import org.springframework.mail.SimpleMailMessage;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.javamail.MimeMessageHelper;import org.springframework.ui.freemarker.FreeMarkerTemplateUtils;import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;import freemarker.template.Configuration;import freemarker.template.Template;public class SpringMail_Batch_Attach_HTML {private Configuration cfg = new Configuration();private static JavaMailSender sender = null;private static FreeMarkerConfigurer freeMarker = null;public static void main(String[] args) throws Exception {// initApplicationContext ctx = new FileSystemXmlApplicationContext("src/applicationContext.xml");JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");SpringMail_Batch_Attach_HTML.sender = sender;SpringMail_Batch_Attach_HTML.freeMarker = (FreeMarkerConfigurer) ctx.getBean("freeMarker");SpringMail_Batch_Attach_HTML springMail = new SpringMail_Batch_Attach_HTML();//发送简单邮件springMail.sendMail(sender);//给某个人发送邮件,基于模板springMail.sendMessage("洒江河风景阿嫂法拉", "wytdq@126.com");//给某些人发送邮件,带附件List toList = new ArrayList();toList.add("xxx@sina.COM");toList.add("xxx@163.COM");toList.add("TIANDEQING@ECODE.NET.CN");springMail.sendBatchEmail("邮件批量发送测试", toList);}// 发送一封文本邮件给一个收件人private void sendMail(JavaMailSender sender) throws Exception {SimpleMailMessage mail = new SimpleMailMessage();mail.setTo("tiandeqing@ecode.net.cn");

3、模板文件src/mail/notify-mail.ftl :
欢迎加入!亲爱的${username}请点击链接完成注册:如果您的email程序不支持链接点击,请将上面的地址拷贝至您的浏览器(如IE)的地址栏进入****。您可以在***:查看最新的影视资料,查看各种相关消费产品,在这里交友,灌水……;希望您在**度过快乐的时光!-(这是一封自动产生的email,请勿回复。)
模板文件src/mail/registerUser.ftl :
<html><head><meta http-equiv="content-type" content="text/html;charset=utf8"></head><body>恭喜您成功注册!您的用户名为:<font color='red' size='30'>${content}</font></body></html>
4、例子使用了FreeMarker。
FreeMarker就是一种用Java编写的模板引擎,它根据模板输出多种规格的文本。
特别指出的是,FreeMarker与Web应用框架无关,它同样可以应用在非Web应用程序环境中。
程序目录结构:
注意在执行代码前,请确认已经将activation.jar,commons-logging-1.0.4.jar,mail.jar和spring.jar载入工程,并且服务器的25端口已开启。
