How I can set my Views files(.html) resource from "webapp" to "resources" folder in SpringMVC project

Today I faced the same problem. I need to transfer templates, css files and images from the webapp folder to the resources folder. In search of an answer, I went through the code of stores that are publicly available on github. I found a project in which all these resources are stored in the resources folder. As I understand it, another class is used there to configure the application. Here is the code. So far, I have not been able to make it work in my project, but I will dig in this direction. Perhaps this will help you too.

package com.geekbrains.geekspring.config;

import org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;

@Configuration
public class AppConfig extends WebMvcAutoConfiguration {
//    public void addResourceHandlers(ResourceHandlerRegistry registry) {
//        if (!registry.hasMappingForPattern("/webjars/**")) {
//            registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
//        }
//    }
}

Ok, I seem to have solved the problem. I think you should be able to too. You only need to change one line of code. My mistake was that when I specified the path in this line: templateResolver.setPrefix("/WEB-INF/views/");

I thought I was specifying it in MyProjectName/src/main/webapp/WEB-INF/views/ This is where my templates used to be. But in fact, I specified the path in the server folder that is generated during compilation based on the folders we created in src. Now this folder is called "target". So, in fact, I pointed the way to MyProjectName/target/shop/WEB-INF/views/

Now I have moved all my templates to MyProjectName/src/main/resources/templates folder Since a new folder has appeared here, then on its basis in the "target" directory at startup project generated a new folder along the path MyProjectName/target/shop/WEB-INF/classes/templates

Accordingly, I indicated a new path following this logic templateResolver.setPrefix("/WEB-INF/classes/templates/");

And everything worked! It remains to transfer css and images.
