Spring实现邮件发送功能

Spring实现邮件发送功能

前言：以前都是直接用java自带的邮件工具发送邮件，现在Spring帮我们做了封装，提供了更好用更简单的发送邮件工具JavaMailSender，关于邮件服务器的设置就不在这里说了，直接去QQ邮箱设置下就好，下面看下主要的步骤：

步骤一、添加发送邮件相关Maven依赖

org.springframework

spring-context-support

4.3.2.RELEASE

javax.mail

mail

1.4.7

步骤二、添加相关Spring配置，创建一个spring-mail.xml（如果是Spring-Boot请无视）,内容如下：

xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:context="http://springframework.org/schema/context"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context.xsd ">

true

25000

xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:context="http://springframework.org/schema/context"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context.xsd ">

true

25000

步骤三、创建具体的邮件发送工具类

/**

* 基于Spring的JavaMailSender的邮件发送工具类

* @author simon

*

*/

@Component

public class EmailSender {

@Autowired

private JavaMailSender javaMailSender;

private static EmailSender emailSender;

@PostConstruct

public void init() {

emailSender = this;

emailSender.javaMailSender= this.javaMailSender;

}

/**

* 发送简单的文本邮件

* @param sendTo 收件人组

* @param subject 主题

* @param content 文本内容

*/

JfaJHvAZ public static void sendSimpleMessage(String sendFrom, String[] sendTo, String subject, String textcontent) {

SimpleMailMessage mail = new SimpleMailMessage();

mail.setFrom(sendFrom);

mail.setTo(sendTo);

mail.setSubject(subject);

mail.setText(textcontent);

//发送

emailSender.javaMailSender.send(mail);

}

/**

* 发送HTML内容格式的邮件

* @param sendFrom

* @param sendTo 收件人组

* @param subject 主题

* @param htmlContent HTML内容

* @throws Exception

*/

public static void sendHtmlMessage(String sendFrom, String[] sendTo, String subject, String htmlContent) throws Exception {

MimeMessage mimeMessage = emailSender.javaMailSender.createMimeMessage();

MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage);

mimeMessageHelper.setFrom(sendFrom);

mimeMessageHelper.setTo(sendTo);

mimeMessageHelper.setSubject(subject);

// true 表示启动HTML格式的邮件

mimeMessageHelper.setText(htmlContent, true);

// 发送邮件

emailSender.javaMailSender.send(mimeMessage);

}

}

步骤四、创建单元测试测试发送邮件

/**

* 邮件发送测试类

*

* @author simon

*

*/

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration("classpath:applicationContext.xml")

public class EmailSenderTest {

@Test

public void testSend() throws Exception {

String sendFrom = "1317492210@qq.com";

String[] sendTo = {"zhaosheng@hitencent.com"};

String subject = "Spring自带JavaMailSender发送的HTML邮件";

StringBuilder htmlContent = new StringBuilder()

.append("")

.append("

.append("

.append("Spring自带JavaMailSender发送的HTML邮件")

.append("

.append("")

.append("

.append("您好!陌生人

.append("")

.append("");

EmailSender.sendHtmlMessage(sendFrom, sendTo, subject, htmlContent.toString());

System.out.println("邮件发送成功.");

}

OK，到这里全部的步骤就结束了，是不是比Java Mail简单方便很多哉，赶紧自己动手试试吧！
