Spring 发送带有内嵌图片和附件的邮件的java程序
java已经将邮件的发送接收封装的很完美，我们使用起来也很方便。
Spring的框架下发送带有内嵌图片和附件的邮件的java程序的小例子。
Spring的配置如下：
<?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="org.springframework.mail.javamail.JavaMailSenderImpl">
<!-- 邮件服务 -->
<property name="host">
<value>smtp.163.com</value>
</property>
<!-- 用户验证-必须 -->
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
</props>
</property>
<!-- 邮件服务用户名 -->
<property name="username">
<value>[email protected]</value>
</property>
<!-- 邮件服务密码 -->
<property name="password">
<value>password</value>
</property>
</bean>
</beans>
java的代码如下：
package cn.com.sl;
import java.io.File;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

// 测试发送只有文本信息的简单测试
// springMail.sendTextMail(sender);

// springMail.sendHtml(sender);
// 测试发送带附件的邮件
springMail.sendMimeMessage(sender);
}

System.out.println("成功发送文本文件！");
}

true);
// 发送邮件
sender.send(mailMessage);
System.out.println("html发送成功.....");
}
/** */
/**

*/
private void sendMimeMessage(JavaMailSender sender) throws Exception {

messageHelper.setFrom("[email protected]");
messageHelper.setSubject("测试附件邮件！");
// true 表示启动HTML格式的邮件
messageHelper.setText(
"<html><head></head><body><h1>hello!!spring image html mail</h1><h2>大家好，这是Spring的邮件发送模块</h2>"
+ "<img src=\"cid:aaa\"/></body></html>", true);
//添加内嵌图片
FileSystemResource img = new FileSystemResource(new File("e:/小海豹.jpg"));
messageHelper.addInline("aaa",img);
//添加附件
FileSystemResource file = new FileSystemResource(new File("e:/小海豹.rar"));
//用于解决邮件显示附件名中含有中文
ClassPathResource fileName =new ClassPathResource("小海豹.rar");
//这里的方法调用和插入图片是不同的。
messageHelper.addAttachment(MimeUtility.encodeWord(fileName.getFilename()),file);
// 发送邮件
sender.send(mailMessage);
System.out.println("附件发送成功.....");
}
