Spring发送带附件邮件 - Spring教程

下面是一个例子使用Spring通过Gmail SMTP服务器来发送电子邮件附件。为了包含附件的电子邮件，你必须使用 Spring的JavaMailSender及MimeMessage 来代替 MailSender＆SimpleMailMessage。

2.Spring的邮件发件人

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。

除了文件系统，您还可以从URL路径(UrlResource对象)，类路径(使用ClassPathResource)，InputStream(InputStreamResource)的任何资源......请参考 Spring 的 AbstractResource 类的实现。

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

配置 mailSender bean，电子邮件模板，并指定Gmail的SMTP服务器电子邮件的详细信息。

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="[email protected]" />
    <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="[email protected]" />
    <property name="to" value="[email protected]" />
    <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
