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

<!-- Spring 邮件发送 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
|
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：

<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.timeout">25000</prop>

</property>
</bean>
</beans>

/**

@Component
public class EmailSender {
@Autowired
private JavaMailSender javaMailSender;
private static EmailSender emailSender;
@PostConstruct
public void init() {
emailSender = this;
emailSender.javaMailSender= this.javaMailSender;
}

SimpleMailMessage mail = new SimpleMailMessage();
mail.setFrom(sendFrom);
mail.setTo(sendTo);

//发送
emailSender.javaMailSender.send(mail);
}

mimeMessageHelper.setFrom(sendFrom);

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

/**

*/
@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("<html>")
.append("<head>")
.append("<title>")
.append("Spring自带JavaMailSender发送的HTML邮件")
.append("</title>")
.append("</head>")
.append("<body>")
.append("您好!陌生人<p/>")
.append("</body>")
.append("</html>");
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！
