I have the following method in the Spring REST controller
#PostMapping("/uploadFile", consumes=["multipart/form-data"])
fun uploadFile(#RequestParam("fileType") fileType: FileType?,
#RequestParam("fileContentType") fileContentType: FileContentType?,
#RequestParam("projectId", required=false) projectId: UUID?,
#RequestParam("fileId", required = false) fileId:UUID?,
#RequestParam("description", required=false) description: String?,
#RequestParam("file") file: MultipartFile): UUID {
My objective is to test this service. I need to upload a file and in the same time give to service wrong "fileId", then parse ErrorMessage. Please tell me how to perform such request? What should I use JAX-RS? ResteasyClient? I have tried ResteasyClient
val inputStream: InputStream = Thread.currentThread().contextClassLoader.getResourceAsStream("application.properties")
val upload = MultipartFormDataOutput()
upload.addFormData("file", inputStream, MediaType.MULTIPART_FORM_DATA_TYPE, "mytarfile.tar")
var request = ClientRequest("http://localhost:$port/api/v1.0/files/uploadFile")
request.formParameter("fileId","test")
request.header("Authorization", "Bearer $accessToken")
request.body(MediaType.MULTIPART_FORM_DATA_TYPE, upload)
val response = request.post(String::class.java)
but it doesn't work
java.lang.RuntimeException: RESTEASY003100: You cannot send both form parameters and an entity body
Moreover ClientRequest is depricated and it is recommended to move to JAX-RS 2.0, could you tell me how to do that??

I'm developing a Spring Boot application and I'm trying to do some authorization/authentication testing using Spock and groovyx.net.http.RESTClient. I'm trying to pass username and password inside body block like this:
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
class AuthorizationTest extends Specification {
#Shared
def client = new RESTClient("http://localhost:8080")
def "something should happen"() {
when:
def response = client.post(
path: "/login",
body: [ password : "1234", username : "admin"],
requestContentType: ContentType.JSON
)
then:
response.status == 200
}
Sadly, something's not working, and when I'm debugging I don't see the two parameters (username and password) inside the request.
What am I doing wrong?
It turned out I need to use different encoding, requestContentType: ContentType.URLENC, which is of type application/x-www-form-urlencoded.
I'm trying to test a GET to get all the StatusMapping objects created, however, I'm not sure what's the best approach to test this.
The response is returning a map whereas I was expecting a list of StatusMapping objects instead.
Should I convert the requests to a map?
Here's the Service code:
fun getAll(): ResponseEntity<List<StatusMapping>> {
return ResponseEntity<List<StatusMapping>>(statusMappingRepository.findAll(), HttpStatus.OK)
}
Here's the test
#Test
fun `Get all mappings created`() {
val requests = listOf(
StatusMapping("available", "available"),
StatusMapping("unavailable", "unavailable")
)
requests.forEach { statusMappingService.createMapping(it.toStatusMappingRequest()) }
val response = restTemplate.getForEntity(getRootUrl(), List::class.java)
assertEquals(response.body, requests)
}
Here's the error that I'm getting:
Expected :[{source=available, target=available}, {source=unavailable, target=unavailable}]
Actual :[StatusMapping(source=available, target=available), StatusMapping(source=unavailable, target=unavailable)]
Please start with replacing
val response = restTemplate.getForEntity(getRootUrl(), List::class.java)
with
val response = restTemplate.exchange(
getRootUrl(),
HttpMethod.GET,
null,
object : ParameterizedTypeReference<List<StatusMapping>>() {})
Assuming that restTemplate is instance of TestRestTemplate
I have a project set up using Spring Boot with Kotlin to make REST APIs.
I'm trying to use the #RequestHeader to recognize the User-Agent. The said header is required=true -
#PostMapping("details", produces = ["application/json"])
fun addInfo(#RequestHeader(name = "User-Agent", required = true) userAgent: String,
#Valid #RequestBody podEntity: PodEntity): ResponseEntity<String> {
pod.addPod(podcastEntity)
return ResponseEntity<String>("{ \"status\":\"Added\" }", HttpStatus.CREATED)
}
Problems -
However, even if I'm not sending the User-Agent header, the API is working and adding data. But, if I change the header to any other non default names, like, user or request-source, the required=true requirement is enforced to and the API does not work. Does it mean that default headers cannot be made mandatory using the required tag?
The other problem is that in the case of custom header, when the required header is missing for the request, the API fails by giving 400 error code but does not throw any exception. I was expecting HttpClientErrorException for my junit test case but on checking the console, I see no exception. Adding #Throws is also not helping. How do enable my function to throw an exception when the required header is missing?
Unit test -
#Test
fun test_getAll_fail_missingHeaders() {
val url = getRootUrl() + "/details/all"
val headers = HttpHeaders()
val request = HttpEntity(pod, headers)
try {
restTemplate!!.postForEntity(url, request, String::class.java)
fail()
} catch (ex: HttpClientErrorException) {
assertEquals(400, ex.rawStatusCode);
assertEquals(true, ex.responseBodyAsString.contains("Missing request header"))
}
}
I have a simple downstream service for file upload. Sample code
#RestController
#RequestMapping("/file")
public class FileController {
#PostMapping("/upload")
public ResponseEntity<?> uploadFile(#RequestParam("file") MultipartFile file,
#RequestParam(value = "delay", required = false, defaultValue = "0") int delay) throws Exception {
System.out.println(String.join(System.getProperty("line.separator"),
"File Name => " + file.getOriginalFilename(),
"File Size => " + file.getSize() + "bytes",
"File Content Type => " + file.getContentType()));
TimeUnit.MILLISECONDS.sleep(delay);
return ResponseEntity.ok(file.getName() + " uploaded");
}
}
and a CustomExceptionHandler that returns BAD_REQUEST if there is a MultipartException:
#Configuration
#ControllerAdvice
public class CustomExceptionHandler {
#ExceptionHandler(MultipartException.class)
public ResponseEntity<String> handleMultipartException(MultipartException ex) {
return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(ex.getMessage());
}
}
The size limit is 10MB in application.yml:
spring:
servlet:
multipart:
max-file-size: 10MB
max-request-size: 10MB
If I upload a large file, it gives me a a 400 status as expected
When I try to hit the same via spring cloud gateway I get the following result:
and the logs shows following:
2019-11-08 00:36:10.797 ERROR 21904 --- [ctor-http-nio-2] a.w.r.e.AbstractErrorWebExceptionHandler : [86e57f7e] 500 Server Error for HTTP POST "/product-service/file/upload"
reactor.netty.http.client.PrematureCloseException: Connection has been closed BEFORE response, while sending request body
Note that the gateway is configured to take in large file size with RequestSize filter set globally to take way more than 10MB.
How can I get the same response code as given by the downstream service?
Also, I check with traditional Zuul, and i get a 500 error too.
For the gateway, for this particular case I know we can use the RequestSize filter and now the gateway will return the error code, but then we have to identify all the routes that expect this beforehand.
Also, other validation in the API, like authorization, etc will have the same the same issue. The response code produced because of these validations will not propagate up.
Sample code spring-cloud-gateway/product-service/eureka - https://github.com/dhananjay12/spring-cloud/tree/master/spring-routing
can you try to go through a non limitation of the volume of the file directly to without going through the getway? try the value -1 for the properties :
properties file of the MS where you want to upload the file
spring.servlet.multipart.max-file-size =-1
spring.servlet.multipart.max-request-size =-1
if it good, it may give a problem with the zuul proxy's ribbon socket size, there are properties informed for this type of situation, the following:
Properties file of the getway :
ribbon.eager-load.enabled=true
hystrix.command.default.execution.timeout.enabled=false
hystrix.command.default.execution.isolation.strategy=THREAD
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=3999996
ribbon.ConnectTimeout=999999
ribbon.ReadTimeout=999999
ribbon.SocketTimeout=999999
zuul.host.socket-timeout-millis=999999
zuul.host.connect-timeout-millis=999999
zuul.sensitiveHeaders=Cookie,Set-Cookie
I'm building a microservice using Spring Boot + Webflux, and I have an endpoint that accepts a multipart file upload. Which is working fine when I test with curl and Postman
#PostMapping("/upload", consumes = [MULTIPART_FORM_DATA_VALUE])
fun uploadVideo(#RequestPart("video") filePart: Mono<FilePart>): Mono<UploadResult> {
log.info("Video upload request received")
return videoFilePart.flatMap { video ->
val fileName = video.filename()
log.info("Saving video to tmp directory: $fileName")
val file = temporaryFilePath(fileName).toFile()
video.transferTo(file)
.thenReturn(UploadResult(true))
.doOnError { error ->
log.error("Failed to save video to temporary directory", error)
}
.onErrorMap {
VideoUploadException("Failed to save video to temporary directory")
}
}
}
I'm now trying to test using WebTestClient:
#Test
fun shouldSuccessfullyUploadVideo() {
client.post()
.uri("/video/upload")
.contentType(MULTIPART_FORM_DATA)
.syncBody(generateBody())
.exchange()
.expectStatus()
.is2xxSuccessful
}
private fun generateBody(): MultiValueMap<String, HttpEntity<*>> {
val builder = MultipartBodyBuilder()
builder.part("video", ClassPathResource("/videos/sunset.mp4"))
return builder.build()
}
The endpoint is returning a 500 because I haven't created the temp directory location to write the files to. However the test is passing even though I'm checking for is2xxSuccessful if I debug into the assertion that is2xxSuccessful performs, I can see it's failing because of the 500, however I'm still getting a green test
Not sure what I am doing wrong here. The VideoUploadException that I map to simply extends ResponseStatusException
class VideoUploadException(reason: String) : ResponseStatusException(HttpStatus.INTERNAL_SERVER_ERROR, reason)
