I am new to RESTful services and jersey. I am trying to send a POST request (using postman) for this function.

@Path("/bikes")
public class BikesResource {

    @POST
    @Consumes ({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
    public void createBike(Bike bike) {
        BikeDao.instance.getModel().put(bike.getBikeID(),bike);
    }

This is my Bike Class:

@XmlRootElement
public class Bike {
    private String bikeID;
    private String ownerName;
    private String color;
    private String gender;

    public Bike(){

    }
    public Bike(String bikeID, String ownerName, String color, String gender){
        this.bikeID = bikeID;
        this.ownerName = ownerName;
        this.color = color;
        this.gender = gender;
    }

    public String getBikeDetails(){
        return getBikeID()   ", "   getOwnerName()   ", "   getColour()   ", "   getGender();
    }
    public String getBikeID(){
        return bikeID;
    }
    public String getOwnerName(){
        return ownerName;
    }
    public String getColour(){
        return color;
    }
    public String getGender(){
        return gender;
    }
    public void setBikeID(String bikeID){
        this.bikeID = bikeID;
    }
    public void setOwnerName(String ownerName){
        this.ownerName = ownerName;
    }
    public void setColour(String colour){
        this.color = colour;
    }
    public void setGender(String gender){
        this.gender = gender;
    }
}

The postman request looks like this: [1]: https://i.stack.imgur.com/N5US9.png

However I get 415 Unsupported Media type and I don't know why. I was thinking that maybe there is something wrong with my pom.xml, but I can't figure it out.

This is the pom.xml file

I would really appreciate some help. Thank you!

CodePudding user response：

Did you check if in Postman's 'Headers' section the ContentType is specified in 'application/json'? maybe the solution is there, it usually happens.

CodePudding user response：

It looks like you don't have JSON/XML Jersey modules to support the media you listed in @Consumes.

Check this doc: https://eclipse-ee4j.github.io/jersey.github.io/documentation/latest/media.html#json

and try:

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-moxy</artifactId>
    <version>2.30.1</version>
</dependency>

(or better, use BOM to lock Jersey versions)
