Java Spring Boot和Thymeleaf:模板解析期间发生错误

我正在开发一个Java Spring Boot Web App,用户可以在其中注册。他们注册时会收到一封确认电子邮件。当我尝试获取电子邮件中的链接以实际确认注册时,此方法不再起作用,因为我收到错误消息:“模板解析期间发生错误(模板:“ mail / verifyEmail.html”)”。我不确定为什么会这样。我已经在verifyEmail.html文件下面附加了文件,然后附加了附带的EmailService.java文件,该文件具有EmailService()和sendVerificationEmail()方法:

<!DOCTYPE html>
<html>

<th:block xmlns:th="http://www.thymeleaf.org">

<span th:text="'Hello ' + ${name}"></span>

<p>Thank you for registering for the bcoreHW site!</p>
<p>Please click <a href="#">here</a> to verify your email address.</p>

</th:block>

import java.util.Date;

import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.mail.javamail.MimeMessagePreparator;
import org.springframework.stereotype.Service;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;
import org.thymeleaf.templateresolver.ClassLoaderTemplateResolver;

@Service
public class EmailService {
    @Autowired
    private JavaMailSender mailSender;

    @Value("${mail.enable}")
    private boolean enable;

    private TemplateEngine templateEngine;

    private void send(MimeMessagePreparator preparator) {
        if(enable) {
            mailSender.send(preparator);
        }
    }

    @Autowired
    public EmailService(TemplateEngine templateEngine) {

        ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
        templateResolver.setPrefix("mail/"); 
        templateResolver.setSuffix(".html");
        templateResolver.setTemplateMode("HTML5");
        templateResolver.setCacheable(false);
        templateEngine.setTemplateResolver(templateResolver);

        this.templateEngine = templateEngine;
    }

    public void sendVerificationEmail(final String emailAddress) {

        Context context = new Context();
        context.setVariable("name", "Bob");

        final String emailContents = templateEngine.process("verifyEmail", context);

        System.out.println(emailContents);

        MimeMessagePreparator preparator = new MimeMessagePreparator() {

            // not working for some reason: @Override
            public void prepare(MimeMessage mimeMessage) throws Exception {

                MimeMessageHelper message = new MimeMessageHelper(mimeMessage);

                message.setTo(emailAddress);
                message.setFrom(new InternetAddress("no-reply@testSite.com"));
                message.setSubject("Please Verify Your Email Address");
                message.setSentDate(new Date());
                message.setText(emailContents, true);
            }
        };

        send(preparator);
    }
}

有人看到这有什么问题吗?谢谢。另外,这是我收到的错误消息:

答案 0 :(得分:0)

我发现了问题。我的前缀“ mail /”不正确,因为它实际上在名为“ mailTemplates”的目录中。愚蠢的我。
