问题
I am using Jersey based restful Service implementation strategy to build a service which will be used to upload files. My service class name is : UploadFileService.java (See Code below)
package com.jerser.service;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;
@Path(\"/fileUpload\")
public class UploadFileService {
@POST
@Path(\"/upload\")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam(\"file\") InputStream uploadedInputStream,
@FormDataParam(\"file\") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = \"d://uploaded/\" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = \"File uploaded to : \" + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
These are the JAR files I have inside my lib:
aopalliance-repackaged-2.4.0-b10.jar asm-debug-all-5.0.2.jar hk2-api-2.4.0-b10.jar hk2-locator-2.4.0-b10.jar hk2-utils-2.4.0-b10.jar javassist-3.18.1-GA.jar javax.annotation-api-1.2.jar javax.inject-2.4.0-b10.jar javax.servlet-api-3.0.1.jar javax.ws.rs-api-2.0.1.jar jaxb-api-2.2.7.jar jersey-client.jar jersey-common.jar jersey-container-servlet-core.jar jersey-container-servlet.jar jersey-core-1.11.jar jersey-guava-2.17.jar jersey-media-jaxb.jar jersey-multipart-1.18.jar jersey-server.jar org.osgi.core-4.2.0.jar osgi-resource-locator-1.0.1.jar persistence-api-1.0.jar validation-api-1.1.0.Final.jar
I am getting the following error when I am trying to up my tomcat server :
org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

Over the internet I found there are plenty of example which shows How to upload MULTIPART file using RESTFul API. But with same solution. I am not able to run those code as well. I think I am doing something wrong with the JAR files. Could anyone please help me on this?
回答1:
Get rid of jersey-multipart-1.18.jar. That is for Jersey 1.x. Add these two
- jersey-media-multipart-2.17
- mimepull-1.9.3
For Maven you would use the following dependency (you don't need to explicitly add the mimepull dependency, as this one will pull it in).
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.17</version> <!-- Make sure the Jersey version matches
the one you are currently using -->
</dependency>
Then you need to register the MultiPartFeature. If you are using a ResourceConfig for configuration, you can simply do
register(MultiPartFeature.class);
If you are using web.xml, then you can add the class as an <init-param> to the Jersey servlet
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>
Note that if you have multiple providers that you want to register, then you can delimit each provider class with a comma or semicolon. You cannot use this same param-name twice. See Suarabh's answer
UPDATE
Also, once you get rid of jersey-multipart-1.18.jar you will have compile errors for the missing imported classes. For the most part, the class names are still the same, just the packages have changed, i.e.
- org.glassfish.jersey.media.multipart.FormDataParam
- org.glassfish.jersey.media.multipart.FormDataContentDisposition
Aside
If you are here for a different ModelValidationException, here are some links for information on other causes of the exception.
- 1
- 2
- 3
回答2:
I too got the same exception.I did the following changes in web.xml
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.moxy.json.MoxyFeature;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>
and changed jersey 2.7 to 2.9 .I do not know what change of this 2 has solved the issue.
回答3:
Register MultiPartFeature. In web.xml add to the Jersey servlet:
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>
回答4:
If someone is using @FormDataParam with @ApiOperation swagger annotation, it won't work(as per swagger latest version at this time) as mentioned here:
https://github.com/swagger-api/swagger-ui/issues/169
回答5:
I had this same problem with Scala and this helped me solve it. Just want to add some Scala specific details to help anyone using Dropwizard with Scala. Here is an example of how to "register" the MultiPartFeature in a Scala and Dropwizard project.
package org.research.s3.service
import io.dropwizard.Application
import io.dropwizard.setup.Environment
import org.research.s3.service.resource._
import org.research.service.s3.resource.UploadResource
import org.glassfish.jersey.media.multipart.{FormDataParam,MultiPartFeature}
class CmdaaApp() extends Application[CmdaaAppConfig] {
override def run(t: CmdaaAppConfig, env: Environment): Unit = {
env.jersey().register(new RootResource)
//Need this to make the file upload code work in
env.jersey().register(new MultiPartFeature)
env.jersey().register(new UploadResource(curBucket))
}
}
object CmdaaApp {
def main(args: Array[String]): Unit = new CmdaaApp().run(args: _*)
}
and here is the code for the UploadResource that does the upload:
package org.research.service.s3.resource
import java.io.{FileInputStream, InputStream}
import com.google.gson.{Gson, GsonBuilder}
import javax.ws.rs.core.MediaType.APPLICATION_JSON
import javax.ws.rs._
import javax.ws.rs.core.Response
import javax.ws.rs.core.MediaType
import org.research.util.OptionSerializer
import org.research.s3.service.resource.s3Bucket
import org.glassfish.jersey.media.multipart.{FormDataParam,MultiPartFeature}
@Path("/file")
class UploadResource(currentBucket: s3Bucket) {
val gsonb = new GsonBuilder()
gsonb.registerTypeAdapter(classOf[Option[Any]], new OptionSerializer)
val gson = gsonb.create
@POST
@Path("upload")
@Produces(Array(APPLICATION_JSON))
@Consumes(Array(MediaType.MULTIPART_FORM_DATA))
// def uploadFile(): Response = {
def uploadFile(@FormDataParam("file") uploadedInputStream: InputStream): Response = {
/* Need code here to get a uuid for the file name
Then return the uuid if we have success and of course 200
*/
Response.ok.entity(currentBucket.upload("testName",uploadedInputStream,false)).build()
//Response.ok().build()
}
}
This code refers to an s3 bucket but you don't need that. You can just replace that call with code do download your incoming file data to a regular file. scala
回答6:
Yet another possible cause for this very generic error is that Jersey only searches for factories associated with the last annotation when multiple ones are declared on a param. (See bug report)
Until this is fixed, if you are using any other annotations besides @FormDataParam, it has to come last.
This works:
@NotEmpty @FormDataParam("myParam") String myParam
This does not:
@FormDataParam("myParam") @NotEmpty String myParam
回答7:
I had the same problem when I tried to upload the file. I spent a lot of time until I found a solution to the problem.
1.If you changed version of your JARs files you may have a version conflicts!
Clean up your artifacts/libs and rebuild project.
2.You need to register your UploadFileService class too:
register(MultiPartFeature.class);
register(UploadFileService.class);
Hope it will help someone and save your time.
