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
@RunWith(SpringRunner.class) @ContextConfiguration(classes=SpringConfig.class) 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); } }
