Thymeleaf：模板可能不存在，或者任何已配置的模板解析程序都无法访问

Question

我有这样的代码：

private static final String EMAIL_INLINEIMAGE_TEMPLATE_NAME = "templateemail.html";

@Bean
public TemplateEngine emailTemplateEngine() {
    templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(this.htmlTemplateResolver());
       )

    templateEngine.setTemplateEngineMessageSource(this.messageSource);
    return templateEngine;
}

private static ITemplateResolver htmlTemplateResolver() {
    final ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setOrder(Integer.valueOf(0));
    templateResolver.setPrefix("classpath:/templates/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode(TemplateResolver.DEFAULT_TEMPLATE_MODE);
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setCacheable(false);
    return templateResolver;
}


public void sendEmail(String emailAddress, String title, String body, Locale local, String image) {
    if (Boolean.parseBoolean(isEmailServiceActivated)) {
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper mailMsg = new MimeMessageHelper(mimeMessage);
        try {
            mailMsg.setFrom(EMAIL_USERNAME);
            mailMsg.setTo(emailAddress);
            mailMsg.setSubject(title);

            // Prepare the evaluation context
            ctx.setLocale(local);
            ctx.setVariable("imageHeaderResourceName", HEADER_LOGO_IMAGE);
            ctx.setVariable("body", body);

            ctx.setVariable("imageResourceName", image);

            final String htmlContent = this.templateEngine.process(new ClassPathResource(EMAIL_INLINEIMAGE_TEMPLATE_NAME).getPath(), ctx);
            mailMsg.setText(htmlContent, true );

            mailMsg.addInline(HEADER_LOGO_IMAGE, new ClassPathResource(HEADER_LOGO_IMAGE ) , PNG_MIME);
            mailMsg.addInline(image, new ClassPathResource(image) , PNG_MIME);

        } catch (MessagingException e) {
            e.printStackTrace();
        }

        mailSender.send(mimeMessage);
    }
}

我在/templates/目录下有templateemail.html文件。当我启动发送电子邮件方法时，我有以下异常：

org.thymeleaf.exceptions.TemplateInputException: Error resolving template "templateemail.html", template might not exist or might not be accessible by any of the configured Template Resolvers

我不知道是因为templateEngine找不到我的文件（我甚至尝试使用tomcat绝对路径和/bin目录，但没有找到），还是因为我没有配置正确的模板解析器。非常感谢你的帮助。我

它现在通过删除模板名称中的“.html”来工作（该文件具有html扩展名）

private static final String EMAIL_INLINEIMAGE_TEMPLATE_NAME = "templateemail"
