File upload using Dropwizard 0.8.0-rc2
Dropwizard 0.7.1 used com.sun.jersey:jersey-server:jar:1.18.1, where version 0.8.0 comes with org.glassfish.jersey.core:jersey-server:jar:2.15.
Before, when uploading files, it was enough to add the com.sun.jersey.contribs:jersey-multipart dependency like so:
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-multipart</artifactId>
<version>1.18.3</version>
</dependency>
This will not work anymore and throws the somewhat cryptic exception: java.lang.IllegalArgumentException: The MultiPartConfig instance we expected is not present. Have you registered the MultiPartConfigProvider class?
The correct dependency should be
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.15</version>
</dependency>
Update your imports and you’re good to go. The same resource will suffice.
@Timed
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public void fileUploaded(@FormDataParam("file") final InputStream inputStream,
@FormDataParam("file") final FormDataContentDisposition contentDispositionHeader) {
storeImage(inputStream);
}
Don’t forget to register the MultiPartFeature in your Application’s run method:
environment.jersey().register(MultiPartFeature.class);
