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
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="mailSender" class="com.heyang.tool.mailsender.MailSenderImpl" singleton="false">
<property name="userName" value="XXXXXXXXXX"/>
<property name="password" value="XXXXXXXX"/>
<property name="stmpServer" value="smtp.163.com"/>
<property name="senderEmailAddr" value="XXXX@XXX.CCC"/>
</bean>
</beans>
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<String> 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");
}
}
