Create a REST API to upload Multipart file data in spring boot

Question

I have created a rest API to accept MULTIPART_FORM_DATA as below. But once I hit the service using Postman, I am getting HTTP Status 415 – Unsupported Media Type exception

@POST
@Path("/fileupload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public String uploadfile(@RequestParam(value = "file") MultipartFile file) {

    System.out.println(file.getName());

    return "Success String";
}

What is wrong here? To consume MediaType.MULTIPART_FORM_DATA, do I need to make any modifications? In Postman I have attached a text file in the BODY and hit the endpoint. The content type is set as "multipart/form-data"

please follow this link: https://stackoverflow.com/questions/16015548/tool-for-sending-multipart-form-data-request It says to remove the content-type from postman. — Brooklyn99, Sep 17 '19 at 17:38

Seems like you are confused with Spring rest API with Rest easy implementation.

In Resteasy, Normal way to handle uploaded file is via MultipartFormDataInput or Map uploaded file to a POJO class via @MultipartForm

You have probably imported different annotations. Try it this way

import org.springframework.web.bind.annotation.*;

import static org.springframework.http.MediaType.*;

@PostMapping(value = "/fileupload", consumes = MULTIPART_FORM_DATA_VALUE, produces = APPLICATION_JSON_VALUE)
public String uploadfile(@RequestParam(value = "file") MultipartFile file) {
    System.out.println(file.getName());
    return "Success String";
}
