小编给大家分享一下怎么用Spring发送电子邮件，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
Spring基于javax.mail封装了一套用于发送电子邮件的API，位于org.springframework.mail包下，下面将介绍下发送普通文本邮件和基于thymeleaf模版的邮件。
<!-- ...... --> <!-- 省略Spring依赖 --> <dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.6.2</version> </dependency>
@PropertySource(value="classpath:mail.properties")
@Configuration
public class SpringConfig {
@Autowired
Environment environment;
/**
* Spring邮件配置
*/
@Bean
public JavaMailSenderImpl javaMailSenderImpl(){
JavaMailSenderImpl javaMailSenderImpl = new JavaMailSenderImpl();
javaMailSenderImpl.setHost(environment.getProperty("mail.host"));
javaMailSenderImpl.setUsername(environment.getProperty("mail.username"));
javaMailSenderImpl.setPassword(environment.getProperty("mail.password"));
javaMailSenderImpl.setDefaultEncoding(environment.getProperty("mail.encoding"));
return javaMailSenderImpl;
}
}#QQ邮箱发送邮件服务器 mail.host=smtp.qq.com #QQ邮箱账户名 mail.username=xxxxxx@qq.com #QQ邮箱授权码，开启IMAP/SMTP服务时会生成 mail.password=lrorsapyffcwbegg #邮件发送编码 mail.encoding=UTF-8

public class MailTest {
@Autowired
private JavaMailSenderImpl javaMailSenderImpl;
@Test
public void testSimpleMail() throws MessagingException{
MimeMessage message = javaMailSenderImpl.createMimeMessage();
//发送带附件和内联元素的邮件需要将第二个参数设置为true
MimeMessageHelper helper = new MimeMessageHelper(message, true);
//发送方邮箱，和配置文件中的mail.username要一致
helper.setFrom("xxxxxx@qq.com");
//接收方
helper.setTo("xxxxxx@qq.com");
//主题
helper.setSubject("邮件测试");
//邮件内容
helper.setText("<html><body><img src='cid:myphoto'></body></html>", true);
//邮件内容内嵌的图片,addInline中的contentId要和邮件内容中的cid相对应
FileSystemResource res = new FileSystemResource(new File("e:/yc/1.jpg"));
helper.addInline("myphoto", res);
//邮件附件
FileSystemResource file = new FileSystemResource(new File("e:/yc/myphoto.zip"));
helper.addAttachment("myphoto.zip", file);
javaMailSenderImpl.send(message);
}
