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")@Configurationpublic class SpringConfig {@AutowiredEnvironment environment;/** * Spring邮件配置 */@Beanpublic 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 {@Autowiredprivate JavaMailSenderImpl javaMailSenderImpl;@Testpublic 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trueMimeMessageHelper 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
@Autowiredprivate TemplateEngine emailTemplateEngine;@Testpublic 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StringContext 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);}
