在工程中经常有发送邮件的任务,如果使用JavaMail来发送邮件，用到的代码较多，过程和细节也相对复杂，而使用Spring的MailSender能相对简单方便些，这样使程序员能更快捷的完成邮件发送任务。下面请看示例代码：
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。
1.抽象邮件发送类BaseMailSender代码；
package com.heyang.tool.mailsender;import org.springframework.mail.MailSender;import org.springframework.mail.SimpleMailMessage;/** *//*** 抽象父类,定义了发送邮件的函数,取得getMailSender函数留待子类实现* @author: 何杨(heyang78@gmail.com)* @date: 2008-8-6-下午03:11:38*/public abstract class BaseMailSender{ protected String userName; protected String password; protected String stmpServer; protected String senderEmailAddr; /** *//** * 取得邮件发送者,留待子类实现 * @return */ protected abstract MailSender getMailSender(); /** *//** * 发送邮件 * @param from :寄信人邮件地址 * @param to :收信人邮件地址 * @param subject :邮件标题 * @param concept :邮件内容 */ public final void sendmail(String to,String subject,String concept){ SimpleMailMessage msg=new SimpleMailMessage(); msg.setFrom(senderEmailAddr); msg.setTo(to); msg.setSubject(subject); msg.setText(concept); MailSender sender=getMailSender(); sender.send(msg); } public void setPassword(String password) { this.password = password; } public void setSenderEmailAddr(String senderEmailAddr) { this.senderEmailAddr = senderEmailAddr; } public void setStmpServer(String stmpServer) { this.stmpServer = stmpServer; } public void setUserName(String userName) { this.userName = userName; }}
二.实现类MailSenderImpl代码。
package com.heyang.tool.mailsender;import java.util.Properties;import org.springframework.mail.MailSender;import org.springframework.mail.javamail.JavaMailSenderImpl;/** *//*** 邮件发送者实现类* @author: 何杨(heyang78@gmail.com)* @date: 2008-8-6-下午03:14:49*/public class MailSenderImpl extends BaseMailSender{ /** *//** * 取得邮件发送者 * @return */ protected MailSender getMailSender(){ JavaMailSenderImpl sender=new JavaMailSenderImpl(); // 邮件发送者邮箱SMTP服务器 sender.setHost(stmpServer); // 邮件发送者邮箱用户 sender.setUsername(userName); // 邮件发送者邮箱密码 sender.setPassword(password); // 客户端认证设置 Properties props = new Properties(); // 同时通过验证 props.put("mail.smtp.auth", "true"); // 存储发送邮件服务器的信息 props.put("mail.smtp.host", stmpServer); // 服务器端认证设置 sender.setJavaMailProperties(props); return sender; }}
三.bean.xml
四.使用示例
package com.heyang.util;import java.util.List;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.heyang.tool.mailsender.BaseMailSender;import com.heyang.tool.mailsender.MailSenderImpl;/** *//*** 异步邮件发送实用类(使用Spring的邮件发送形式)* @author: 何杨(heyang78@gmail.com)* @date: 2008-8-6-下午02:43:22*/public final class MailUtil { /** *//** * 发送邮件 * @param emailAddr:收信人邮件地址 * @param mailTitle:邮件标题 * @param mailConcept:邮件内容 */ public static void sendmail(final String emailAddr, final String mailTitle, final String mailConcept) { Runnable thread=new Runnable(){ public void run(){ ApplicationContext context = new ClassPathXmlApplicationContext("bean.xml"); BaseMailSender sender=(MailSenderImpl)context.getBean("mailSender"); sender.sendmail(emailAddr, mailTitle, mailConcept); } }; new Thread(thread).start(); } /** *//** * 向系统维护者发送邮件 * @param mailTitle * @param mailConcept */ public static void sendmailToSupporters(final String mailTitle, final String mailConcept){ Runnable thread=new Runnable(){ public void run(){ ApplicationContext context = new ClassPathXmlApplicationContext("bean.xml"); SupportTeam supportTeam=(SupportTeam)context.getBean("supportTeam"); BaseMailSender sender=(MailSenderImpl)context.getBean("mailSender"); List mails=supportTeam.getSupporterEmails(); for(String mailAddr:mails){ sender.sendmail(mailAddr, mailTitle, mailConcept); } } }; new Thread(thread).start(); } /** *//** * 测试邮件发送 * @param args */ public static void main(String[] args){ MailUtil.sendmailToSupporters("title_spring", "concept_spring"); }}
