The traditional way of uploading a file is to use a form submission. In this tutorial, I will be discussing a different approach of uploading a file. This tutorial will begin with an overview of the sample application's architecture. This allows us to pack the file content into a JSON object to be sent. On the server side, the request handling method will parse the file content and revert the BASE64 string back into a binary file.
For this tutorial, I have created a sample program to demonstrate the functionalities that would be discussed in this tutorial. This application will be a Spring Boot based application.

It hosts a RESTFul web service that can handle only one kind of request - our request for file upload. It will handle the file being uploaded. This method will take a JSON object that has two properties, one is a short file name, and the other is the content of the file.
The application also contains an index page which is actually a single-page web application implemented using AngularJS. The application has a single input that can load a file from disk. Once file is selected, the application will load the file content and get the file name just the file name, not the path. All these will be explained in the next few sections. When I first started working on the sample application, the very first task I had to do is design an HTML element that can get a file from local disk.
Let's see how this is done. There is an input control available in HTML that does this. I know. What I need is not this predefined input control. What I need is a readonly text field, and a button grouped together. The button can be clicked and pops up the File Open dialog so it can be used to select a file. The text field will display the file name.
With Bootstrap, this is very easy to define:. In the code snippet above, there are some attributes specific for AngularJS.
You can ignore these for now.Bootstrap File Input is a field which the user can use to upload one or more files photos, documents or any other file type from local storage.
