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:

ERROR: org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mailManager': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.thymeleaf.TemplateEngine no.test.lab.manager.MailManager.templateEngine; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.thymeleaf.TemplateEngine] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Do you have any other Spring configuration files? – geoand
Yes, there is a number of configuration files. Spring batch, integration, security, etc. The beans above was actually from mvc-dispatcher-servlet.xml – Jaffa
Is component scanning enabled in mvc-dispatcher-servlet.xml or some other file? – geoand
Yes. I updated the question with the entire mvc-dispatcher-servlet.xml. The application is being migrated from JSP/Tiles to Thymeleaf, so there is a view resolver for JSP/Tiles as well. If I remove the autowired TemplateEngine from the service class, everything else is working (except the mail template part of course). – Jaffa

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.
