简介
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。
普通邮件
导入javax.mail依赖
- <!-- ...... -->
- <!-- 省略Spring依赖 -->
- <dependency>
- <groupId>com.sun.mail</groupId>
- <artifactId>javax.mail</artifactId>
- <version>1.6.2</version>
- </dependency>
Spring配置类
- @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;
- }
- }
邮件配置：mail.properties
- #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
测试
- @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);
- }
- }
基于thymeleaf模版的邮件
导入thymeleaf-spring依赖
- <dependency>
- <groupId>org.thymeleaf</groupId>
- <artifactId>thymeleaf-spring4</artifactId>
- <version>3.0.11.RELEASE</version>
- </dependency>
Spring配置类中添加thymeleaf模板配置
- @Bean
- public TemplateEngine emailTemplateEngine() {
- SpringTemplateEngine templateEngine = new SpringTemplateEngine();
- ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
- templateResolver.setResolvablePatterns(Collections.singleton("*.html"));
- templateResolver.setPrefix("/templates/");
- templateResolver.setSuffix(".html");
- templateResolver.setTemplateMode(TemplateMode.HTML);
- templateResolver.setCharacterEncoding("UTF-8");
- templateResolver.setCacheable(false);
- templateEngine.addTemplateResolver(templateResolver);
- return templateEngine;
- }
模版文件：/src/main/resources/templates/msg.html
- <!DOCTYPE html>
- <html xmlns:th="http://www.thymeleaf.org">
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
- <style type="text/css">span{color:orange}</style>
- </head>
- <body>
- <p>
- 您好， <span th:text="${name}">xxx</span>，感谢您使用XXX服务，您正在进行邮箱验证，本次请求的验证码为：
- </p>
- <p><span th:text="${validCode}">1111</span>(为了保障您帐号的安全性，请在1小时内完成验证。)</p>
- <p>
- XXX团队<br />
- 2019年06月06日
- </p>
- </body>
- </html>
测试
- @Autowired
- private TemplateEngine emailTemplateEngine;
- @Test
- public void testTemplateMail() throws MessagingException{
- MimeMessage message = javaMailSenderImpl.createMimeMessage();
- MimeMessageHelper helper = new MimeMessageHelper(message, true);
- helper.setFrom("xxxxxx@qq.com");
- helper.setTo("xxxxxx@qq.com");
- helper.setSubject("邮件测试");
- //thymeleaf模版解析成String
- Context ctx = new Context();
- ctx.setVariable("name", "小姐姐");
- ctx.setVariable("validCode", "88888888");
- String htmlContent = emailTemplateEngine.process("msg.html", ctx);
- helper.setText(htmlContent, true);
- javaMailSenderImpl.send(message);
- }
