Spring Boot调用thymeleaf模板失败

Question

我得到了这个错误，我在堆栈上搜索了我的相同问题，我发现我不应该在调用它时放. html，但我得到了相同的错误：

`Caused by: org.thymeleaf.exceptions.TemplateInputException: Error resolving template "orderConfirmationEmailTemplate", template might not exist or might not be accessible by any of the configured Template Resolver`s

我的邮件构造函数：

@Component
public class MailConstructor {

    @Autowired
    private Environment env;

    @Autowired
    private TemplateEngine templateEngine;

    public SimpleMailMessage constructNewUserEmail(User user, String password) {
        String message="\nPlease use the following credentials to log in and edit your personal information including your own password."
                + "\nUsername:"+user.getUsername()+"\nPassword:"+password;

        SimpleMailMessage email = new SimpleMailMessage();
        email.setTo(user.getEmail());
        email.setSubject("Le's Bookstore - New User");
        email.setText(message);
        email.setFrom(env.getProperty("support.email"));
        return email;
    }

    public MimeMessagePreparator constructOrderConfirmationEmail (User user, Order order, Locale locale) {
        Context context = new Context();
        context.setVariable("order", order);
        context.setVariable("user", user);
        context.setVariable("cartItemList", order.getCartItemList());
        String text = templateEngine.process("orderConfirmationEmailTemplate.html", context);

        MimeMessagePreparator messagePreparator = new MimeMessagePreparator() {
            @Override
            public void prepare(MimeMessage mimeMessage) throws Exception {
                MimeMessageHelper email = new MimeMessageHelper(mimeMessage);
                email.setTo(user.getEmail());
                email.setSubject("Order Confirmation - "+order.getId());
                email.setText(text,true);
                email.setFrom(new InternetAddress("[e-mail]"));
            }
        };

        return messagePreparator;
    }

我从Rest服务中心打电话给它：

mailSender.send(mailConstructor.constructOrderConfirmationEmail(user, order, Locale.ENGLISH));

    shoppingCartService.clearShoppingCart(shoppingCart);

我正在放文件。项目中包下的html

Answer 1

实际上，当我的配置被放入我的问题中时，我只是把。html文件下的文件称为模板下的资源和它的工作邮件被发送，Spring开机显然是自动配置与此路径没有配置templateResolver

Answer 2

在你的问题中，TemplateEngine是自动连接的，因此我看不到它是如何配置的，但它是为了从位置com发现你的模板。书店领域安全模板配置应如下所示：

@Bean
public TemplateEngine templateEngine() {
    final SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(templateResolver());
    return templateEngine;
}

private ITemplateResolver templateResolver() {
    final ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setPrefix(“/com/bookstore/domain/security/templates“);
    templateResolver.setSuffix(".html");
    …
    return templateResolver;
}

在这段代码中，我正在代码中配置模板引擎，可能您正在使用XML。无论您如何配置模板引擎，很明显您是在使用Spring来实现这一点（因为您将其注入到您的邮件构造函数中），这里的关键点是，无论您如何配置它，您都需要告诉它在哪里找到您的模板，并且方法是调用ITemplateResolver的setPrefix（）方法。

在Thymeleaf docs中，有一篇题为“在Spring用Thymeleaf发送电子邮件”的文章提供了更多详细信息。
