再写一个组件实现上面的接口并注入JavaMailSender
@Component public class IMailServiceImpl implements IMailService { @Autowired private JavaMailSender mailSender; @Value("${spring.mail.from}") private String from; //具体实现请继续向下阅读 } 发送文本邮件 /** * 发送文本邮件 * @param to * @param subject * @param content */ @Override public void sendSimpleMail(String to, String subject, String content) { SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(from); message.setTo(to); message.setSubject(subject); message.setText(content); mailSender.send(message); } @Override public void sendSimpleMail(String to, String subject, String content, String... cc) { SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(from); message.setTo(to); message.setCc(cc); message.setSubject(subject); message.setText(content); mailSender.send(message); } 发送html邮件 /** * 发送HTML邮件 * @param to * @param subject * @param content */ @Override public void sendHtmlMail(String to, String subject, String content) throws MessagingException { MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); mailSender.send(message); }省略实现带有抄送方法的实现
发送带附件的邮件 /** * 发送带附件的邮件 * @param to * @param subject * @param content * @param filePath */ public void sendAttachmentsMail(String to, String subject, String content, String filePath) throws MessagingException { MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); FileSystemResource file = new FileSystemResource(new File(filePath)); String fileName = filePath.substring(filePath.lastIndexOf(File.separator)); helper.addAttachment(fileName, file); mailSender.send(message); }省略实现带有抄送方法的实现
发送正文中有静态资源的邮件 /** * 发送正文中有静态资源的邮件 * @param to * @param subject * @param content * @param rscPath * @param rscId */ public void sendResourceMail(String to, String subject, String content, String rscPath, String rscId) throws MessagingException { MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); FileSystemResource res = new FileSystemResource(new File(rscPath)); helper.addInline(rscId, res); mailSender.send(message); }省略实现带有抄送方法的实现
发送模板邮件发送模板邮件使用的方法与发送HTML邮件的方法一致。只是发送邮件时使用到的模板引擎,这里使用的模板引擎为Thymeleaf。
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>模板HTML代码如下:
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>IJPay让支付触手可及</title> <style> body { text-align: center; margin-left: auto; margin-right: auto; } #welcome { text-align: center; position: absolute; } </style> </head> <body> <div> <h3>欢迎使用 <span th:text="${project}"></span> -By <span th:text=" ${author}"></span></h3> <span th:text="${url}"></span> <div> <a href="#" th:href="@{${url}}" target="_bank"> <strong>IJPay让支付触手可及,欢迎Start支持项目发展:)</strong> </a> </div> <div> 如果对你有帮助,请任意打赏 </div> <img src="http://oscimg.oschina.net/oscnet/8e86fed2ee9571eb133096d5dc1b3cb2fc1.jpg"> </div> </body> </html>如何使用请看测试中实现的代码。
