必须使用 JavaMailSender 代替 MailSender 发送附件，并用 MimeMessageHelper 附加的资源。在这个例子中，它会得到 “c:\\log.txt” 从文件系统(FileSystemResource)作为电子邮件附件的文本文件。

File : MailMail.java

package com.yiibai.common;

import javax.mail.MessagingException;

import javax.mail.internet.MimeMessage;

import org.springframework.core.io.FileSystemResource;

import org.springframework.mail.MailParseException;

import org.springframework.mail.SimpleMailMessage;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.MimeMessageHelper;

public class MailMail

{

	private JavaMailSender mailSender;

	private SimpleMailMessage simpleMailMessage;

	public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {

		this.simpleMailMessage = simpleMailMessage;

	}

	public void setMailSender(JavaMailSender mailSender) {

		this.mailSender = mailSender;

	}

	public void sendMail(String dear, String content) {

	   MimeMessage message = mailSender.createMimeMessage();

	   try{

		MimeMessageHelper helper = new MimeMessageHelper(message, true);

		helper.setFrom(simpleMailMessage.getFrom());

		helper.setTo(simpleMailMessage.getTo());

		helper.setSubject(simpleMailMessage.getSubject());

		helper.setText(String.format(

			simpleMailMessage.getText(), dear, content));

		FileSystemResource file = new FileSystemResource("C:\\log.txt");

		helper.addAttachment(file.getFilename(), file);

	     }catch (MessagingException e) {

		throw new MailParseException(e);

	     }

	     mailSender.send(message);

         }

}

3. Bean配置文件

File : Spring-Mail.xml

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

	<property name="host" value="smtp.gmail.com" />

	<property name="port" value="587" />

	<property name="username" value="yiibai.com@gmail.com" />

	<property name="password" value="password" />

	<property name="javaMailProperties">

		<props>

           	<prop key="mail.smtp.auth">true</prop>

           	<prop key="mail.smtp.starttls.enable">true</prop>

       	</props>

	</property>

</bean>

<bean id="mailMail" class="com.yiibai.common.MailMail">

	<property name="mailSender" ref="mailSender" />

	<property name="simpleMailMessage" ref="customeMailMessage" />

</bean>

<bean id="customeMailMessage"

	class="org.springframework.mail.SimpleMailMessage">

	<property name="from" value="from@no-spam.com" />

	<property name="to" value="to@no-spam.com" />

	<property name="subject" value="Testing Subject" />

	<property name="text">

	<value>

		<![CDATA[

			Dear %s,

			Mail Content : %s

		]]>

	</value>

    </property>

</bean>

</beans>

4. 运行它

package com.yiibai.common;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App

{

    public static void main( String[] args )

    {

    	ApplicationContext context =

            new ClassPathXmlApplicationContext("applicationContext.xml");

    	MailMail mm = (MailMail) context.getBean("mailMail");

        mm.sendMail("Yiibai", "This is text content");

    }

}

输出结果

Dear Yiibai,

 Mail Content : This is text content

 Attachment : log.txt
