Spring boot serving static resource

Question

I work on spring boot application. I'm trying to serve static content with spring. want to serve a resource stored in the /c:/frontend/files/ directory whenever a request comes in for the URL matching the pattern: /file/**:

 @Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry
            .addResourceHandler("/file/**")
            .addResourceLocations("file:///C:/frontend/files/" );

}

but when i try to access to this resource using this url: http://localhost:9999/file/app.min.js

I have this problem

There was an unexpected error (type=Not Acceptable, status=406).
Could not find acceptable representation

Answer 1

I resolved the problem. it's related to "spring-cloud-config-server". I just delete this config: org.springframework.cloud spring-cloud-config-server

It sounds like your project's folder structure is wrong.

Code should go under src/main/java and resources (like your javascript) should go under src/main/resources . You have a few different options where you can actually serve the files from. This post on the spring.io blog has the following to say:

Spring Boot will automatically add static web resources located within any of the following directories:

• /META-INF/resources/
• /resources/
• /static/
• /public/

Another option you also have is using webjars .

Personally, I've found it easiest to put those kind of files under src/main/resources/public . It always works without any issues for me. The interesting thing is you can put a folder named /public anywhere in your project and spring-boot will serve files out of it. You have to be really careful that it's under src/main/resources/public though if you're using a build tool like maven, as when you come to build your .jar the files won't be in the right place otherwise.
