If you can't use ThymeleafDatabaseResourceResolver the other option would be to fetch your template manually in java code, and then process it:

String databaseTemplate = ...fetch template from db...
Context context = new Context(Locale.ENGLISH);
...set variables for context....
String processedTemplate = templateEngine.process(databaseTemplate, context);

You should also manually create template engine:

SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.addTemplateResolver(new SpringResourceTemplateResolver());
templateEngine.addTemplateResolver(new StringTemplateResolver());
templateEngine.addTemplateResolver(new FileTemplateResolver());

This would work if your database contains either path to the template file or template content itself. However if you are sure that your database always holds a path to file, then you can just autowire standard TemplateEnging configured by spring-boot.

Also you might want to take a look at ITemplateResolver interface and its implementations, in case your templates are located somewhere else.
