Download file using spring rest web service java

In our application. Now let's create a POJO class called StorageProperties and annotate it with ConfigurationProperties to automatically bind the properties defined in application. It instructs ConfigurationProperties to bind all the properties that start with storage prefix to their corresponding attributes of POJO class when the application is started.

The next step is to enable the ConfigurationProperties feature by adding EnableConfigurationProperties annotation to our main configuration class.

Let's now create a controller class called FileController for handling uploading and downloading files via RESTful web services. It also defines a route to list all the uploaded files. As always, our controller class is annotated with Controller to let the Spring MVC pick it up for routes.

The FileController class uses the StorageService interface for storing and resolving files in the file system. It is the most important class for handling files in our example. We'll define these classes in the next section. In production, it's not advised to store the uploaded files in your application file system.

You might lose all files if your application server is damaged. It also makes very difficult to move the application from one server to another. Therefore, it is a good practice to use external storage like AWS S3 for storing all the uploaded files. I'll write about this topic in the future. Finally, it is time to create a storage service called StorageService for our controller to connect with a storage layer e.

This task involves several classes. We'll define these classes one-by-one. The above interface declares several abstract methods for initializing, storing, removing and retrieving files. Learn more.

I have 3 machines: server where the file is located server where REST service is running Jersey client browser with access to 2nd server but no access to 1st server How can I directly without saving the file on 2nd server download the file from 1st server to client's machine?
