open fun setPreTemplateLoaders(vararg preTemplateLoaders: TemplateLoader): Unit
Set a List of TemplateLoaders that will be used to search for templates. For example, one or more custom loaders such as database loaders could be configured and injected here.
The TemplateLoader specified here will be registered before the default template loaders that this factory registers (such as loaders for specified "templateLoaderPaths" or any loaders registered in #postProcessTemplateLoaders).
