Spring File Upload - 'Required request part is not present'

Question

I am trying to send POST request to my controller but cannot pass any parameter in any type unless I decide to use JSON. My goal is to pass a String and a file to my controller but I keep getting Required request part 'xxx' is not present error.

@RestController
public class ConfigurationController {
    @PostMapping(value = "/config")
    public ResponseEntity<?> saveEnvironmentConfig(@RequestParam("file") MultipartFile uploadfile){
        return ResponseEntity.ok().body(null);
    }
}

I cannot have file here. Similarly if I try:

@RestController
public class ConfigurationController {
    @PostMapping(value = "/config")
    public ResponseEntity<?> saveEnvironmentConfig(@RequestParam("name") String name){
        return ResponseEntity.ok().body(null);
    }
}

same thing I cannot get name here.

I am sending request via Postman as given in following screenshot:

The only header tag is for Authorization. I do not have any Content-Type header, I tried to add multipart/form-data but did not help.

Only way I could pass String parameter is by adding to URL. So following http://localhost:8080/SearchBox/admin/config?name=test works but this is not what I want. I want String and File parameters in Body part.

I also tested via CURL:

curl -X POST -H "Authorization:Bearer myToken" -H "Content-Type:Multipart/form-data" http://localhost:8080/SearchBox/admin/config --data 'pwd=pwd'
curl -X POST -H "Authorization:Bearer myToken"http://localhost:8080/SearchBox/admin/config --data 'pwd=pwd'
curl -H "Authorization:Bearer myToken" -F file=@"/g123.conf" http://localhost:8080/SearchBox/admin/config

For others with a similar problem, this may be the solution you're looking for: #40489085 – Sharpeared

You have to add bean multipartResolver in your addConfig in case you using spring mvc. Like this baeldung.com/spring-file-upload – Rafaelle

Answer 1

I finally solved the issue and sharing my solution in case someone else may face the same problem.

@RestController
@RequestMapping("/")
public class ConfigurationController {

    @Bean
    public MultipartConfigElement multipartConfigElement() {
        return new MultipartConfigElement("");
    }

    @Bean
    public MultipartResolver multipartResolver() {
        org.springframework.web.multipart.commons.CommonsMultipartResolver multipartResolver = new org.springframework.web.multipart.commons.CommonsMultipartResolver();
        multipartResolver.setMaxUploadSize(1000000);
        return multipartResolver;
    }
    @PostMapping(value = "/config", consumes = "multipart/form-data")
    public ResponseEntity<?> saveEnvironmentConfig(@RequestParam("password") String password, @RequestParam("file") MultipartFile submissions)
            throws AdminAuthenticationException, ConfigurationException {
        return ResponseEntity.ok().body(null);
    }
}

This does not work for me in Spring 2.0.0. In fact, adding those beans creates exactly that error. Adding none won't cause an error. – Pernambuco

@Gokhan why do you use multipartResolver() and multipartConfigElement() method. – Gilberte

adding @Bean public MultipartConfigElement multipartConfigElement() { return new MultipartConfigElement(""); } and works in Spring Boot 2.1.6 thanks! – Lukey

please can you share the Junit test case for this controller. I am finding difficulty in sending file as post request – Nickinickie

Answer 2

In my case the issue was that my csv was not named as per the string set within

@PostMapping("/upload")
    public ResponseEntity<ResponseMessage> uploadFile(@RequestParam("file") MultipartFile file) {

Answer 3

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public ResponseEntity<?> upload(@RequestParam(value = "name") String 
name,@RequestParam(value = "file") MultipartFile file){
    // TODO check file is not null and save 
    return new ResponseEntity<>(HttpStatus.valueOf(200));;
}

Volturno

Same :( {"message":"Required String parameter 'title' is not present","status":400,"errors":["Required String parameter 'title' is not present"]} – Tequilater

change the parameter format for "file" from Text to File from drop down menu and select the file you wanted to upload – Volturno

update the first parameter to this @RequestParam(value = "name") String name – Volturno

I already changed the name. It seems I required Bean definition. Please see my answer. It solved my problem. Thank you for helping – Tequilater

or you can add spring.http.multipart.max-file-size=100Mb in applications.properties configuration file – Volturno

I dont know why, but interchanging the params, i.e. putting multipart file first and string next solved the issue for me – Gleich

Answer 4

Add Bean to Config file.

@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    multipartResolver.setMaxUploadSize(-1);
    return multipartResolver;

}

Answer 5

Really not sure what was going on but I removed the code

=======REMOVE BELOW========

@Bean
public MultipartConfigElement multipartConfigElement() {
    return new MultipartConfigElement("");
}

@Bean
public MultipartResolver multipartResolver() {

Added below:

spring.servlet.multipart.max-file-size=-1 
spring.servlet.multipart.max-request-size=-1

And, it starting working magically! Maybe thats how it was with my spring version.

Answer 6

While this was not the original poster's problem, if you found this question and none of the above solutions worked for you, check your Postman headers; if "Content-Type" header is set, this may cause the error above.

Remove the "Content-Type" header and it may resolve the issue above.

See this question for more information:

Postman : Required request part 'file' is not present

Sharpeared

Answer 7

If you still getting error, try to remove all headers from postman and drop type of file

Hyacinth

Thanks, solved my problem of testing with webtestclient. I removed header of Content-Type. I think webtestclient will add it – Belleslettres

Answer 8

I suspect that main reason is @RequestParam("file") there should be @RequestBody instead.

Crankcase

@RequestBody @RequestParam("name") String name did not work. When I try @RequestBody String name name variable get following value: ------WebKitFormBoundary6WJHhVqqZrh8qeAX Content-Disposition: form-data; name="name" test ------WebKitFormBoundary6WJHhVqqZrh8qeAX-- – Tequilater

Upvoting this answer as through it realised the name I was expecting for my file ("file") was not matching what I was setting on Postman. Thank you. – Edme

Answer 9

Consider also the possibility of your request body not reaching your server if it's going through a proxy or any other intermediary that may not support multipart/form-data or even octet-stream content types. Hopefully, this can be solved with extra configuration to work this kind of requests. I can also recommend you to configure a request interceptor so you can log your request before and after your controller, this might help you getting a peek into the request parameters, payload and headers. In my case I realized that the size of my request body was 0, which help me to detect what was causing this error wasn't my spring configuration. Here I leave a useful resource to help you with the logging interceptor which Spring has out of the box. enter link description here

Answer 10

In my case the name attribute of the input type file was not set as "file".

<input type="file" class="file-input" id="fileUpload" name="file">

Spellbinder

Answer 11

In my case solution was missing '@EnableWebMvc' annotation on configuration

@EnableWebMvc
@Configuration
internal class BulkOffersUploadConfig {

    @Bean
    fun multipartResolver(): MultipartResolver {
        val multipartResolver = CommonsMultipartResolver()
        multipartResolver.setMaxUploadSize(1000)
        multipartResolver.setMaxUploadSizePerFile(1000)
        return multipartResolver
    }
}

Example of a multipart/form-data JMeter POST:

HTTP Header Manager:
Accept  */*
Content-Type    multipart/form-data; boundary=------------------------jm888
Expect  100-continue
User-Agent  jmeter/3.3
HTTP Request:
uncheck the following:
Redirect Automatically
Follow Redirects
User KeepAlive
Use multipart/form-data for POST
Browser-compatible headers
Select Body Data tab
sample of Body Data:
------------------------jm888
Content-Disposition: form-data; name="microsvc"
Content-Type: application/json
