配置JavaMailSender

@ComponentScan(basePackages = "com.ooyhao.spring", useDefaultFilters = true,
        excludeFilters = {
                @ComponentScan.Filter(type = FilterType.ANNOTATION, classes = Controller.class),
                @ComponentScan.Filter(type = FilterType.ANNOTATION, classes = RestController.class)
        }
)
public class RootConfig {
    @Bean
    public JavaMailSender javaMailSender() {
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
        mailSender.setHost("smtp.163.com");
        mailSender.setUsername("ooyhao1996@163.com");
        mailSender.setPassword("163mailcode");
        mailSender.setDefaultEncoding("utf-8");
        return mailSender;
    }
}

項目結構圖

發送簡單郵件

@Service
public class SendMailService {

    @Autowired
    private JavaMailSender mailSender;

    /**
     * 發送簡單郵件消息
     */
    public void sendSimpleMail(){
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom("ooyhao1996@163.com");
        message.setTo("625194996@qq.com");
        message.setSubject("郵件");
        message.setText("郵件");
        message.setSentDate(new Date());
        mailSender.send(message);
    }
}

發送帶有附件的郵件

@Service
public class SendMailService {

    @Autowired
    private JavaMailSender mailSender;

    public void sendMailWithAttachment() throws MessagingException {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setFrom("ooyhao1996@163.com");
        helper.setTo("625194996@qq.com");
        helper.setSentDate(new Date());
        helper.setSubject("帶有附件的郵件");
        helper.setText("這是一封具備附件的郵件");
        /*能夠攜帶多個附件*/
        ClassPathResource resource1 = new ClassPathResource("images/123.png");
        helper.addAttachment("123.png",resource1);
        ClassPathResource resource2 = new ClassPathResource("images/456.png");
        helper.addAttachment("456.png",resource2);
        mailSender.send(mimeMessage);
    }
}

發送HTML郵件

@Service
public class SendMailService {

    @Autowired
    private JavaMailSender mailSender;

    /*發送一封HTML郵件*/
    public void sendHtmlMail() throws MessagingException {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setFrom("ooyhao1996@163.com");
        helper.setTo("625194996@qq.com");
        helper.setSentDate(new Date());
        helper.setSubject("HTML郵件");
        helper.setText("<!DOCTYPE html>\n" +
                "<html>\n" +
                "<head>\n" +
                "\t<title>HTML郵件</title>\n" +
                "</head>\n" +
                "<body>\n" +
                "\t<h1>這是一份HTML郵件</h1>\n" +
                "\t<img src=\"cid:logo\">\n" +
                "</body>\n" +
                "</html>",true);
        ClassPathResource resource = new ClassPathResource("res/images/logo.png");
        helper.addInline("logo",resource);
        mailSender.send(mimeMessage);
    }
}

發送模板郵件

使用模板郵件發送時，須要配置模板解析器和模板引擎。java

@Bean
public ClassLoaderTemplateResolver emailTemplateResolver(){
  ClassLoaderTemplateResolver resolver = new ClassLoaderTemplateResolver();
  resolver.setPrefix("mail/");
  resolver.setTemplateMode(TemplateMode.HTML);
  resolver.setCharacterEncoding("utf-8");
  return resolver;
}

/*配置*/
@Bean
public SpringResourceTemplateResolver templateResolver(){
  SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
  resolver.setTemplateMode(TemplateMode.HTML);
  resolver.setSuffix("/WEB-INF/templates/");
  resolver.setSuffix(".html");
  resolver.setCharacterEncoding("utf-8");
  return resolver;
}


@Bean
public SpringTemplateEngine templateEngine(Set<ITemplateResolver> templateResolvers){
  SpringTemplateEngine engine = new SpringTemplateEngine();
  engine.setTemplateResolvers(templateResolvers);
  return engine;
}
@Service
public class SendMailService {

    @Autowired
    private JavaMailSender mailSender;

    @Autowired
    private SpringTemplateEngine springTemplateEngine;
  
    /*發送一封使用Thymeleaf模板生成的郵件*/
    public void sendTemplateHTML() throws MessagingException {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setFrom("ooyhao1996@163.com");
        helper.setTo("625194996@qq.com");
        helper.setSentDate(new Date());
        helper.setSubject("HTML郵件");
        Context context = new Context();
        context.setVariable("firstTitle","這是一封模板生成的郵件");
        context.setVariable("secondTitle","模板郵件|ouyanghao");
        context.setVariable("src","https://ooyhao.gitee.io/vuepress-blog/logo.png");
        String emailText = springTemplateEngine.process("emailTemplate.html", context);
        helper.setText(emailText,true);
        mailSender.send(mimeMessage);
    }
}

HTML模板mysql

<!DOCTYPE html>
<html lang="en"
      xmlns="http://www.w3.org/1999/xhtml"
      xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1 th:text="${firstTitle}">一級標題</h1>
    <h2 th:text="${secondTitle}">二級標題</h2>
    <img th:src="${src}"><!--這裏須要填寫公網地址，localhost沒法顯示 -->

</body>
</html>

​ 發送HTML(Thymeleaf)模板郵件時，須要注意一些細節，好比上述代碼中的圖片顯示，則須要用一張外網能夠訪問到的圖片，不然郵件中沒法正常顯示。git

總結：web

​ 本節重要是練習如何使用Spring中的簡單方法來實現郵件發送。而且包含了簡單郵件、附件郵件、HTML郵件以及模板郵件。spring

源碼：sql
