Sto utilizzando la strategia di implementazione del servizio restful basata su Jersey per creare un servizio che verrà utilizzato per caricare i file. Il mio nome classe di servizio è: UploadFileService.java (vedi codice qui sotto)MULTIPART_FORM_DATA: Nessuna fonte di iniezione trovata per un parametro di tipo public javax.ws.rs.core.Response
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();
}
}
}
Questi sono i file JAR che ho dentro il mio 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
sto ottenendo il seguente errore quando provo a caricare il mio server tomcat:
org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

Su internet Ho trovato che ci sono molti esempi che mostrano come caricare file MULTIPART usando l'API RESTFul. Ma con la stessa soluzione. Non sono in grado di eseguire anche questo codice. Penso che stia facendo qualcosa di sbagliato con i file JAR. Qualcuno potrebbe aiutarmi per favore su questo?
Più 1 per web.xml e ResourceConfig. – kyle
Wow questo ha risolto il mio problema. Grazie mille. – orange14
Per utenti dropwizard. Uno deve includere la dipendenza dai moduli dropwizard e registrare il bundle nel metodo initialize(): http://dropwizard.readthedocs.io/en/latest/manual/forms.html – Vyacheslav
