Rest api upload file example java

Uploading files to web-apps is a common task nowadays. A lot of services support uploading pictures or documents on their sites. With Java web services this is easy accomplished. What we need aside form the java web container provided by your application server like TomcatGlassFish or JBoss is the jersey framework to make it run.

First I will show you how to implement the web-service and than give you two examples of clients to use the service. This way you can add multiple parameters to the POST request in addition to the file.

Lets start with the requirements. In addition we will use jersey framework to build our service endpoint. Please note, GlassFish 4. I will post the entire POM file here, but what you need to take into account are the jersey dependencies. There are several places in the code below I want to point your attention to. Second you may want to add additional parameters to the method if you like.

For example you may want to pass some description or another text data with your upload. Now you can build and deploy the WAR file. As I already mentioned you can add additional data to your request.

I the example below I will use Apache http libraries, you will need this five:. Servlets are the building…. This tutorial will explain how to create Java JAR file with Maven with step by step guidelines and screen shots. That was from the github version of this. Secondly, I started looking at this tutorial because of the use of multipart, as I want to add parameters as part of the upload. Is there somewhere I could find an example of that usage?

Thank you for your comment Sandstones! Good remark with the -1 in the service URL. The POM file is not part of Glassfish server. It is part of your Java Maven project. Follow the steps in the New Maven Project Wizzard.

This will create a POM file for you. You can edit this file and add the required dependencies. According to your how can I configure it to use the code above or I need to create a new project over the old version instead? Just follow this steps:.

The jQuery document. Add the file to the Shared Documents folder by using the Add method on the folder's file collection. The array buffer is passed in the body of the POST request. Get the list item that corresponds to the uploaded file by using the ListItemAllFields property of the uploaded file. The first example uses SP. AppContextSite to make calls across SharePoint domains, like a SharePoint-hosted add-in would do when uploading files to the host web.

The second example makes same-domain calls, like a SharePoint-hosted add-in would do when uploading files to the add-in web, or a solution that's running on the server would do when uploading files. Provider-hosted add-ins written in JavaScript must use the SP. RequestExecutor cross-domain library to send requests to a SharePoint domain.

For an example, see upload a file by using the cross-domain library. Write permissions to the Documents library for the user running the code. If you're developing a SharePoint Add-in, you can specify Write add-in permissions at the List scope. The context for this example is a SharePoint-hosted add-in that uploads a file to a folder on the host web.

You need to meet the requirements listed in the section Running the code examples to use this example. The context for this example is a solution that's running on the server.

Lets define the spring specific configurations in springexamples-servlet. Here we are using annotation to define the RestController class and its request handler. To process all the annotation we have provided base package com.

The class is marked up with RestController annotationwhich accept HTTP web-service requests and returns the response. Simple upload method is written which helps to upload file at destination location, In which you need to pass a MultipartFile as a method parameter e. RequestParam "file" MultipartFile inputFile. Hi there! I am founder of technicalkeeda.

If you have any idea that you would want me to develop? Lets connect: yashwantchavan[at][gmail. Login Registration. Let's define the spring specific maven dependencies. File; import javax. ServletContext; import org. Autowired; import org. HttpHeaders; import org. HttpStatus; import org. ResponseEntity; import org. RequestMapping; import org. RequestMethod; import org. RequestParam; import org.

RestController; import org. MultipartFile; import com. Once you submit the request, It will start uploading the file to server location and display the file information like file path and file size. Server response with uploaded file details. Yashwant Hi there!Learn to upload multiple multipart binary files e.

Apart from spring webmvcwe will need commons-fileupload and commons-io in classpath. It is Servlet-based MultipartResolver implementation for commons-fileupload.

I am assuming at employee with id '1' exist in database. Feel free to change the resource path and implementation. Above REST controller creates a upload folder with name as employee id if not already present in filesystem.

Still we need to define following property. Also, the controller returns the Callable which means the method returns immediately while the IO operations may run. Once the upload process is finished, API returns the response. To enable async supportconfigure async-supported in DispatcherServlet. For demo purpose, I have created a JSP page with only multiple fields of type file. We will browse few images from computer, and upload them to server. Browser the images and click on Submit button.

The image files will be uploaded to server in configured upload directory.

File-sharing is one of the most elementary ways to perform system integration. But we would like all this information to arrive on the server in the same request.

This guide will demonstrate one strategy, among many, to implement this integration scenario using resources provided by Mule components. Just to contextualize, this strategy was inspired by the architecture of a legacy project that I needed to maintain.

After the conversion, the String is deposited inside an XML tag, which is part of the Body content of the payload that is being transmitted to the remote server [see fig2]. There is an advantage to using this strategy, which is the ability to transmit this tag in the same payload that may contain other information, such as the data needed to process business rules, or better still contain the meta information of the file. This is very desirable because it conforms to one of the great features of the HTTP protocol which was designed to be Stateless and allows the transaction to be completely processed in one request.

I thought that some of the advantages identified in the architecture applied in the legacy solution context, and so I built a way to port this architecture to a REST API, applying also significant improvements.

You are able to do all of this before you make a minimal implementation available to run on some server.

A ForEach traverses the inboundAttachment of the current message a multipart-formData to separate the FileContent [] from the filesData. There is also a component to remove the rootMessage variable generated during the interaction of the ForEach. This is done here to simplify for the consumer the activity of passing binary data within a JSON. This object is partitioned, each part represents a file that will be sent to the outbound VM component where each file is processed separately.

The Collection Aggregator component is responsible for gathering the enriched payloads in the same structure.

As suggested by the MuleSoft documentation, we can use an inbound VM to handle requests that originate from a Message Splitter. Within this Flow, each file is pre-processed and then sent to Amazon S3 by the Create Object operation. This variable satisfies the Create Object component, along with the file and bucket names. We can complete this step with the help of DataWeave—— the data received at the beginning of this flow is enriched with the FileSize and HttpURI data that was received in the response of the S3 Get Object operation.

It offers some exception treatments handled automatically by APIKit. Stress tests can be generated with the help of the JMeter tool.

Tests can also be performed on newer versions of SoapUI. Please note that I opted to perform the tests with the help of the Postman tool an extension for the Google Chrome browser.
