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测试数据" ); //接收方 helper . setTo ( "xxxxxx@qq测试数据" ); //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://HdhCmsTestthymeleaf.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测试数据" ); helper . setTo ( "xxxxxx@qq测试数据" ); 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 ); }
