Thymeleaf Spring 메일 컨텍스트 오류

Question

저는 thymeleaf 템플릿 엔진을 사용하여 스프링 메일을 구성하려고하는데, 왜 그런 일이 발생하는지 알 수없는 오류가 있습니다. 나는이 문제에 대해 다양한 주제를 보았지만 문제를 해결하기위한 모든 제안은 내 프로젝트에서 옳은 것처럼 보인다.

문제는 ServletContextTemplateResolver로 해결하려는 Context 문제입니다.

내 구성은 다음과 같습니다

@Transactional(readOnly = true) 
public void sendContactEmail (final String recipientName, final String recipientEmail, final String imageResourceName, final byte[] imageBytes, final String imageContentType, final Locale locale) throws MessagingException 
{ 
    // Prepare the evaluation context 
    final Context ctx = new Context(locale); 
    ctx.setVariable("name", recipientName); 
    ctx.setVariable("subscriptionDate", new Date()); 
    ctx.setVariable("hobbies", Arrays.asList("Cinema", "Sports", "Music")); 
    ctx.setVariable("imageResourceName", imageResourceName); // so that we can reference it from HTML 

    // Prepare message using a Spring helper 
    final MimeMessage mimeMessage = this.mailSender.createMimeMessage(); 
    final MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true, "UTF-8"); // true = multipart 
    message.setSubject("Example HTML email with inline image"); 
    message.setFrom("thymeleaf@example.com"); 
    message.setTo(recipientEmail); 

    // Create the HTML body using Thymeleaf 
    final String htmlContent = this.templateEngine.process("contact.html", ctx); 
    message.setText(htmlContent, true); // true = isHtml 

    // Add the inline image, referenced from the HTML code as "cid:${imageResourceName}" 
    final InputStreamSource imageSource = new ByteArrayResource(imageBytes); 
    message.addInline(imageResourceName, imageSource, imageContentType); 

    // Send mail 
    this.mailSender.send(mimeMessage); 
} 

그리고 마지막으로 오류 :

@Bean 
public TemplateResolver webTemplateResolver() { 
    final TemplateResolver templateResolver = new ServletContextTemplateResolver(); 
    templateResolver.setPrefix("/WEB-INF/views/"); 
    templateResolver.setSuffix(".html"); 
    templateResolver.setTemplateMode("HTML5"); 
    templateResolver.setOrder(2); 
    return templateResolver; 
} 

@Bean 
public TemplateResolver emailTemplateResolver() { 
    TemplateResolver templateResolver = new ClassLoaderTemplateResolver(); 
    templateResolver.setPrefix("mail/"); 
    templateResolver.setSuffix(".html"); 
    templateResolver.setTemplateMode("HTML5"); 
    templateResolver.setOrder(1); 
    return templateResolver; 
} 

@Bean 
public SpringTemplateEngine templateEngine (IMessageResolver messageResolver) { 
    final SpringTemplateEngine templateEngine = new SpringTemplateEngine(); 
    templateEngine.addTemplateResolver(webTemplateResolver()); 
    templateEngine.addTemplateResolver(emailTemplateResolver()); 
    templateEngine.addDialect(new LayoutDialect()); 
    templateEngine.addDialect(new SpringSecurityDialect()); 
    templateEngine.addMessageResolver(messageResolver); 
    return templateEngine; 
}

희망 누군가가 도움이 될 수 있습니다. 미리 감사드립니다.

감사합니다.

Answer 1

좋아, thymeleaf 디버깅 문제를 찾을 수 있습니다. 엔진을 템플릿을 해결하도록 알려주는 방법이 잘못되었습니다. 이 줄 :

// Create the HTML body using Thymeleaf 
final String htmlContent = this.templateEngine.process("contact.html", ctx); 

리졸버로는 키우면 그것이 분명한 이유의 원인이 발견되지 않도록 "contant.html.html"라는 이름의 템플릿을 찾기 위해 노력하고있다

templateResolver.setSuffix(".html"); 

이 방법을 구성 .

처리 드 템플릿이 방법 :

이

// Create the HTML body using Thymeleaf 
final String htmlContent = this.templateEngine.process("contact", ctx); //Note .html not present 

applicaciont가 완벽하게 작동합니다.

이상한 점은 thymeleaf 워드 프로세서의 예제에는 html suffi가 있지만 시도해 보았지만 정상적으로 작동한다는 것입니다.

thymeleaf 버전이 이러한 차이를 일으킬 수 있습니까? 2.1.4.RELEASE

는

2.1.3.RELEASE.
