Java 8 Upload File to Directory Tutorial

Uploading and downloading files are very common tasks for which developers need to write code in their applications.

In this article, You'll learn how to upload and download files in a RESTful spring kicking web service.

We'll first build the REST APIs for uploading and downloading files, then test those APIs using Postman. We'll likewise write forepart-end lawmaking in javascript to upload files.

Following is the final version of our application -

Spring Boot File Upload and Download AJAX Rest API Web Service All right! Let's get started.

Creating the Awarding

Let'due south generate our awarding using Spring Boot CLI. Fire up your terminal, and type the post-obit command to generate the app -

            $ spring init --proper noun=file-demo --dependencies=web file-demo Using              service              at https://start.spring.io Project extracted to              '/Users/rajeevkumarsingh/spring-boot/file-demo'                      

You may also generate the application through Spring Initializr spider web tool past post-obit the instructions below -

  1. Open http://first.spring.io
  2. Enter file-demo in the "Antiquity" field.
  3. Enter com.example.filedemo in the "Parcel" field.
  4. Add Web in the "Dependencies" department.
  5. Click Generate to generate and download the project.

That's it! Yous may now unzip the downloaded application archive and import information technology into your favorite IDE.

Configuring Server and File Storage Properties

Commencement affair First! Allow's configure our Bound Boot application to enable Multipart file uploads, and define the maximum file size that can exist uploaded. Nosotros'll also configure the directory into which all the uploaded files will be stored.

Open src/main/resource/application.properties file, and add together the following properties to it -

                          ## MULTIPART (MultipartProperties)              # Enable multipart uploads              spring.servlet.multipart.enabled              =              true              # Threshold after which files are written to disk.              spring.servlet.multipart.file-size-threshold              =              2KB              # Max file size.              jump.servlet.multipart.max-file-size              =              200MB              # Max Asking Size              spring.servlet.multipart.max-request-size              =              215MB              ## File Storage Properties              # All files uploaded through the Residue API will exist stored in this directory              file.upload-dir              =              /Users/callicoder/uploads                      

Note: Please change the file.upload-dir property to the path where y'all want the uploaded files to be stored.

Automatically binding properties to a POJO form

Bound Kicking has an awesome characteristic called @ConfigurationProperties using which you can automatically bind the properties defined in the awarding.properties file to a POJO class.

Let's define a POJO form called FileStorageProperties inside com.example.filedemo.property package to bind all the file storage properties -

                          package              com.instance.filedemo.property              ;              import              org.springframework.boot.context.properties.                            ConfigurationProperties              ;              @ConfigurationProperties              (prefix              =              "file"              )              public              class              FileStorageProperties              {              private              String              uploadDir;              public              Cord              getUploadDir              (              )              {              render              uploadDir;              }              public              void              setUploadDir              (              Cord              uploadDir)              {              this              .uploadDir              =              uploadDir;              }              }                      

The @ConfigurationProperties(prefix = "file") notation does its task on application startup and binds all the properties with prefix file to the corresponding fields of the POJO class.

If you lot ascertain additional file backdrop in time to come, y'all may simply add a respective field in the above class, and spring boot will automatically demark the field with the property value.

Enable Configuration Properties

Now, To enable the ConfigurationProperties feature, you demand to add @EnableConfigurationProperties annotation to any configuration form.

Open the main grade src/master/java/com/instance/filedemo/FileDemoApplication.java, and add the @EnableConfigurationProperties note to it like and so -

                          package              com.example.filedemo              ;              import              com.example.filedemo.property.                            FileStorageProperties              ;              import              org.springframework.boot.                            SpringApplication              ;              import              org.springframework.boot.autoconfigure.                            SpringBootApplication              ;              import              org.springframework.kick.context.properties.                            EnableConfigurationProperties              ;              @SpringBootApplication              @EnableConfigurationProperties              (              {              FileStorageProperties              .              class              }              )              public              course              FileDemoApplication              {              public              static              void              principal              (              Cord              [              ]              args)              {              SpringApplication              .              run              (              FileDemoApplication              .              class              ,              args)              ;              }              }                      

Writing APIs for File Upload and Download

Permit's now write the Rest APIs for uploading and downloading files. Create a new controller class called FileController within com.example.filedemo.controller package.

Here is the complete code for FileController -

                          package              com.example.filedemo.controller              ;              import              com.example.filedemo.payload.                            UploadFileResponse              ;              import              com.instance.filedemo.service.                            FileStorageService              ;              import              org.slf4j.                            Logger              ;              import              org.slf4j.

filename=\""              +              resources.              getFilename              (              )              +              "\""              )              .              torso              (resource)              ;              }              }                      

The FileController form uses FileStorageService for storing files in the file system and retrieving them. It returns a payload of blazon UploadFileResponse later the upload is completed. Let'due south define these classes one past one.

UploadFileResponse

Equally the name suggests, this class is used to return the response from the /uploadFile and /uploadMultipleFiles APIs.

Create UploadFileResponse grade inside com.case.filedemo.payload packet with the post-obit contents -

                          package              com.example.filedemo.payload              ;              public              grade              UploadFileResponse              {              private              Cord              fileName;              individual              String              fileDownloadUri;              individual              Cord              fileType;              private              long              size;              public              UploadFileResponse              (              String              fileName,              String              fileDownloadUri,              String              fileType,              long              size)              {              this              .fileName              =              fileName;              this              .fileDownloadUri              =              fileDownloadUri;              this              .fileType              =              fileType;              this              .size              =              size;              }              // Getters and Setters (Omitted for brevity)              }                      

Service for Storing Files in the FileSystem and retrieving them

Let's now write the service for storing files in the file system and retrieving them. Create a new class called FileStorageService.java inside com.instance.filedemo.service package with the following contents -

                          package              com.example.filedemo.service              ;              import              com.example.filedemo.exception.

Exception Classes

The FileStorageService form throws some exceptions in example of unexpected situations. Following are the definitions of those exception classes (All the exception classes go within the package com.example.filedemo.exception).

one. FileStorageException

It's thrown when an unexpected state of affairs occurs while storing a file in the file organisation -

                          package              com.instance.filedemo.exception              ;              public              form              FileStorageException              extends              RuntimeException              {              public              FileStorageException              (              Cord              bulletin)              {              super              (message)              ;              }              public              FileStorageException              (              Cord              message,              Throwable              cause)              {              super              (bulletin,              cause)              ;              }              }                      

ii. MyFileNotFoundException

Information technology's thrown when a file that the user is trying to download is non found.

                          packet              com.example.filedemo.exception              ;              import              org.springframework.http.                            HttpStatus              ;              import              org.springframework.web.bind.annotation.                            ResponseStatus              ;              @ResponseStatus              (              HttpStatus              .NOT_FOUND)              public              class              MyFileNotFoundException              extends              RuntimeException              {              public              MyFileNotFoundException              (              Cord              bulletin)              {              super              (bulletin)              ;              }              public              MyFileNotFoundException              (              String              bulletin,              Throwable              cause)              {              super              (message,              crusade)              ;              }              }                      

Note that, we've annotated the above exception class with @ResponseStatus(HttpStatus.NOT_FOUND). This ensures that Leap boot responds with a 404 Non Plant status when this exception is thrown.

If you lot employ JQuery

If you adopt using jQuery instead of vanilla javascript, then you can upload files using jQuery.ajax() method similar and then -

                          $              (              '#singleUploadForm'              )              .              submit              (              part              (              event              )              {              var              formElement              =              this              ;              // You can directly create form data from the form element              // (Or you lot could get the files from input chemical element and append them to FormData as nosotros did in vanilla javascript)              var              formData              =              new              FormData              (formElement)              ;              $.              ajax              (              {              type:              "POST"              ,              enctype:              'multipart/form-information'              ,              url:              "/uploadFile"              ,              data:              formData,              processData:              false              ,              contentType:              fake              ,              success              :              function              (              response              )              {              console.              log              (response)              ;              // procedure response              }              ,              fault              :              office              (              mistake              )              {              console.              log              (error)              ;              // process error              }              }              )              ;              event.              preventDefault              (              )              ;              }              )              ;                      

Conclusion

All right folks! In this article, we learned how to upload single as well as multiple files via Remainder APIs written in Jump Boot. Nosotros besides learned how to download files in Jump Kick. Finally, nosotros wrote code to upload files past calling the APIs through javascript.

I hope the post was helpful to you. You lot can download the entire lawmaking for the project that nosotros built in this commodity from the github repository.

If you want to store files in MySQL database instead of the local file system, and so bank check out the following commodity -
