415: Unsupported media type (while consuming JSON input to JAX-RS service)

[Chandan Sharma, modifié il y a 6 années.]

I am trying to consume JSON as input to JAX-RS service. But I am getting: 415: Unsupported media type.

While searching through Google, got some suggestion for adding below dependency (in build.gradle):

compile group: 'org.glassfish.jersey.media', name: 'jersey-media-json-jackson', version: '2.9'
compile group: 'org.glassfish.jersey.media', name: 'jersey-media-moxy', version: '2.9'

Here is my sample code:

package org.chandan.leave.rest.application;

import java.text.SimpleDateFormat;
import java.util.Collections;
import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.MediaType;

import org.chandan.leave.exception.NoSuchLeaveException;
import org.chandan.leave.model.Leave;
import org.chandan.leave.rest.modal.Employee;
import org.chandan.leave.rest.modal.Status;
import org.chandan.leave.service.LeaveLocalService;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

import com.liferay.portal.kernel.json.JSONFactoryUtil;

@ApplicationPath("/leave")
@Component(immediate = true, service = Application.class)
public class LeaveRestControllerApplication extends Application {

	public Set<object> getSingletons() {
		return Collections.<object>singleton(this);
	}
	private LeaveLocalService leaveLocalService;
	
	@Reference(unbind="-")
	public void setLeaveLocalService(LeaveLocalService leaveLocalService){
		this.leaveLocalService=leaveLocalService;
	}

	
	@POST
	@Path("/add-emp")
	@Consumes(MediaType.APPLICATION_JSON)
	@Produces(MediaType.APPLICATION_JSON)
	public Employee addEmp(Employee emp){
		
		System.out.println(emp.getFirstName() + " " + emp.getLastName());
		
		Employee newEmp = new Employee();
		newEmp.setFirstName("Chandan");
		newEmp.setLastName("Sharma");
		
		return newEmp;
	}

Hello Chandan! I'm not that well-versed with JAX-RS but I had some ideas/questions. May be they can help

First of all, what is your Liferay version?

Chandan Sharma:

While searching through Google, got some suggestion for adding below dependency (in build.gradle):

Well, I never needed these dependencies when working with JAX-RS on portal. OTOH I needed Apache CXF, so I used these dependencies:

provided group: "org.apache.cxf", name: "cxf-core", version: "3.0.3"
provided group: "org.apache.cxf", name: "cxf-rt-frontend-jaxrs", version: "3.0.0"
provided group: "org.apache.cxf", name: "cxf-rt-rs-extension-providers", version: "3.0.3"

Chandan Sharma:

Here is my sample code:

Is your Employee class annotated with @XmlRootElement? Could you post it here?

Hi guys,

just a quick question, what "Accept" and "Content-Type" header do you use in your HTTP request from client? It should be application/json !

[Chandan Sharma, modifié il y a 6 années.]

It worked @Adam Victor Brandizzi after adding @XmlRootElement

It didn't required to add Apache CXF dependencies. Although I tried to add it but got Build failed.

Thanks you for your help

And coming to

Tomas Polesovsky:

Hi guys,

Yes I had used it "Accept" and "Content-Type" header with value application/json, while making request earlier.

Thanks @Thomas for your help
