问题描述
我正在尝试将 Thymeleaf 电子邮件模板添加到正在运行的 Spring MVC + Thymeleaf 应用程序中，如here.
当我尝试在我的服务类中自动装配 TemplateEngine 时收到此错误:

您需要将 templateEngine 移动到根应用程序上下文，因为这是您的 MailManager 定义的地方.您当前配置 Spring 的方式，templateEngine 是在 web 应用程序上下文中定义的，这意味着来自根上下文的 bean 不能使用它.
为了做到这一点，只需将 templateEngine bean 及其依赖项移动到 Spring 配置文件中，您已在其中为 controller 以外的包启用了组件扫描.
I'm trying to add Thymeleaf email templates to a working Spring MVC + Thymeleaf application as described here.
I receive this error when I try to autowire the TemplateEngine in my service class:

You need to move the templateEngine to the root application context since that is where your MailManager is defined. The way you have currently configured Spring, templateEngine is defined in the web application context which means that beans from the root context cannot use it.
In order to do that just move the templateEngine bean along with it's dependencies to the Spring configuration file where you have enabled component scanning for the packages other than controller.
