Spring boot pdf download

By default, the copy fails if the target file already exists or is a symbolic link. Once, this process is completed, the response will be the download URL of the file. We will discuss the file download in a moment. Below is the sample request that we can make to test this functionality from Postman. You can also use javascript or any other JS library to test it.

The multiple files upload internally invokes above method to repeat the single file upload. We can also have a functionality to upload a. To add an extra parameter with file upload, we can append that extra parameter in the form data at the client-side and the same can be retrieved as a request param at the server-side.

Below is an example where we appended the key as extraParam in the form data at client-side. For this, we need to have a database configuration first.

Spring boot provides a very convenient way to do so by adding a few properties in application. We will be using spring data JPA for our purpose. To save the uploaded file in the DB, we have a model class and we are using byte[] as a data type to save it in the DB.

Below is the REST implementation for this. The implementation is similar to above logic except it has a DB call to save the file instead of saving it to the local file system.

Here, we will be using ZipOutputStream from java. Below is the example. To test this functionality, we can make a GET request with name as a query parameter which includes all the file names that we want to be included in the final.

We tested the above implementation with Postman. But in my previous tutorial, we have created other tutorials to achieve the same functionality with popular Javascript framework and library. You can follow this article to implement the file uploading client with Angular and this tutorial with React Js.

In this article, we disussed about different ways to upload and download files and images with spring boot REST and tested with Postman. A technology savvy professional with an exceptional capacity to analyze, solve problems and multi-task.
