How to refresh a folder using java program in intellij / Eclipse? (Solved)

I am currently working on a Spring Boot project while uploading images the image get created in resources\static\images but when I'm trying to display the image it is not showing. After I refresh the folder it get reflected.
Here is my code:

// Method for uploading image.
	public void uploadImage(MultipartFile file) {
		byte[] bytes = new byte[0];
		try {
			bytes = file.getBytes();
		} catch (IOException e) {
			e.printStackTrace();
		}
		BufferedOutputStream stream = null;
		try {
			stream = new BufferedOutputStream(new FileOutputStream(new File(
					"D:\\New Language\\Spring Boot Demo\\employee_details\\src\\main\\resources\\static\\images"
							+ File.separator + file.getOriginalFilename())));
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		try {
			stream.write(bytes);
			stream.flush();
			stream.close();

		} catch (IOException e) {
			e.printStackTrace();
		}
		
	}


// JSP Code For displaying image.   
    <div class="card-header border-0">
        <img src="/images/${emp.path}" alt="My Image">
    </div>                                                   

You shouldn't change it in the source folder. I'm not 100% sure, but I think IntelliJ will use .../target/classes/ as classpath, and will copy files there during compile. Spring Boot will load any /static folder it finds on the classpath.
So you could overwrite files there instead of under .../src/main/resources. That will work until IntelliJ decides to overwrite them during a compile or doing a mvn clean install.

Also, if you run the spring boot app standalone, the resources will be inside a jar file, so that's not a good idea to use as dynamic storage.

Better to create a separate folder for dynamic storage, and configure it as follows:

spring.resources.static-locations=classpath:/static/,file:/D:/...

Off course, if you update that folder at runtime, it's not really static anymore. Check also https://www.baeldung.com/spring-mvc-static-resources

So finally after 3 days I found the solution to this problem.
Since resources\static\images\ place is about static content and since it is in general a bad idea to save uploaded (dynamic) content inside your application. So I created a folder outside of resources folder and put all the uploaded (dynamic) images files.

Here is how I solved this problem.
Create a new class and try this.

@Configuration
public class ResourceWebConfiguration implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(final ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/images/**").addResourceLocations("file:images/");
    }
}
