Question

我正在尝试使用百日咳模板发送电子邮件。但我收到一条错误消息

org.thymeleaf.exceptions.TemplateProcessingException: Resource resolution by ServletContext with org.thymeleaf.resourceresolver.ServletContextResourceResolver can only be performed when context implements org.thymeleaf.context.IWebContext [current context: org.thymeleaf.context.Context]

10936 [taskScheduler-1] ERROR org.thymeleaf.TemplateEngine - [THYMELEAF][taskScheduler-1] Exception processing template "scheduleMail.html": Resource resolution by ServletContext with org.thymeleaf.resourceresolver.ServletContextResourceResolver can only be performed when context implements org.thymeleaf.context.IWebContext [current context: org.thymeleaf.context.Context]

我不能使用WebContext（）而不是Context（）。因为对于webContext我需要HttpServletRequest对象，我无法在这里获取，因为它不在请求范围内。我试图使用context（）发送邮件，但我收到一个错误。请有人对此有解决方案。提前致谢这是我的代码，

final Context ctx = new Context(); 
    ctx.setVariable("eagletId", user.getEagletId());
    ctx.setVariable("name", user.getFirstName());
    ctx.setVariable("setSentDate", new Date());
    ctx.setVariable("department", user.getDepartment());
    ctx.setVariable("batch", user.getBatch());
    // ctx.setVariable("month" Constants.LeapConstants.UserType);

    // Prepare message using a Spring helper 
    final MimeMessage mimeMessage = this.mailSender.createMimeMessage(); 
    final MimeMessageHelper message =  
            new MimeMessageHelper(mimeMessage, true /* multipart */, "UTF-8"); 
    message.setSubject("Create your report for month"); 
    message.setFrom("leap@gmail.com"); 
    message.setTo("vlab@gmail.com"); 

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

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

您的模板引擎配置了ServletContextTemplateResolver，而不是FileTemplateResolver或ClassLoaderTemplateResolver。这将在某个地方的spring配置文件中定义。如果在代码中配置，请参阅Thymeleaf user's guide on configuring the template engine和configuration of the templateResolver。这是个好文档。

通过xml配置，它看起来像这样：

<beans:bean id="templateResolver"
    class="org.thymeleaf.templateresolver.ClassLoaderTemplateResolver">
</beans:bean>

在Spring Scheduler中使用thymeleaf发送邮件
