오류 415 지원되지 않는 미디어 유형 : JSON 인 경우 POST가 REST에 도달하지 않지만 XML 인 경우에는 도달합니다.

---

나는 실제로 REST WS를 처음 접했지만 실제로는 이것을 얻지 못했습니다 415 Unsupported Media Type.

나는 파이어 폭스에 포스터 내 REST를 테스트입니다 그리고는 GET또한 나를 위해 잘 작동합니다 POST(그것의 때 application/xml내가하려고 할 때) 그러나 application/json이 모든에 WS 도달하지 않는 서버는 그것을 거부합니다.

이것은 내 URL입니다 : http : // localhost : 8081 / RestDemo / services / customers / add

이것은 JSON내가 보내는 것입니다.{"name": "test1", "address" :"test2"}

이것은 XML내가 보내는 것입니다.

<customer>
    <name>test1</name>
    <address>test2</address>
</customer>

그리고 이것은 내 리소스 클래스입니다.

@Produces("application/xml")
@Path("customers")
@Singleton
@XmlRootElement(name = "customers")
public class CustomerResource {

    private TreeMap<Integer, Customer> customerMap = new TreeMap<Integer, Customer>();

    public  CustomerResource() {
        // hardcode a single customer into the database for demonstration
        // purposes
        Customer customer = new Customer();
        customer.setName("Harold Abernathy");
        customer.setAddress("Sheffield, UK");
        addCustomer(customer);
    }

    @GET
    @XmlElement(name = "customer")
    public List<Customer> getCustomers() {
        List<Customer> customers = new ArrayList<Customer>();
        customers.addAll(customerMap.values());
        return customers;
    }

    @GET
    @Path("/{id}")
    @Produces("application/json")
    public String getCustomer(@PathParam("id") int cId) {
        Customer customer = customerMap.get(cId); 
        return  "{\"name\": \" " + customer.getName() + " \", \"address\": \"" + customer.getAddress() + "\"}";

    }

    @POST
    @Path("/add")
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public String addCustomer(Customer customer) {
         //insert 
         int id = customerMap.size();
         customer.setId(id);
         customerMap.put(id, customer);
         //get inserted
         Customer result = customerMap.get(id);

         return  "{\"id\": \" " + result.getId() + " \", \"name\": \" " + result.getName() + " \", \"address\": \"" + result.getAddress() + "\"}";
    }

}

편집 1 :

이것은 내 고객 클래스입니다.

@XmlRootElement 
public class Customer implements Serializable {

    private int id;
    private String name;
    private String address;

    public Customer() {
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

}

문제는 Bean Customer의 직렬화 해제에 있습니다. 여러분의 프로그램은 Daniel이 작성하는 JAXB를 사용하여 XML로 수행하는 방법을 알고 있지만 JSON으로 수행하는 방법을 모를 가능성이 높습니다.

Here you have an example with Resteasy/Jackson http://www.mkyong.com/webservices/jax-rs/integrate-jackson-with-resteasy/

The same with Jersey: http://www.mkyong.com/webservices/jax-rs/json-example-with-jersey-jackson/

Add Content-Type: application/json and Accept: application/json in REST Client header section

---

Just in case this is helpful to others, here's my anecdote:

I found this thread as a result of a problem I encountered while I was using Postman to send test data to my RESTEasy server, where- after a significant code change- I was getting nothing but 415 Unsupported Media Type errors.

Long story short, I tore everything out, eventually I tried to run the trivial file upload example I knew worked; it didn't. That's when I realized that the problem was with my Postman request. I normally don't send any special headers, but in a previous test I had added a "Content-Type": "application/json" header. OF COURSE, I was trying to upload "multipart/form-data." Removing it solved my issue.

Moral: Check your headers before you blow up your world. ;)

I had this issue and found that the problem was that I had not registered the JacksonFeature class:

// Create JAX-RS application.
final Application application = new ResourceConfig()
    ...
    .register(JacksonFeature.class);

Without doing this your application does not know how to convert the JSON to a java object.

I had the same problem:

curl -v -H "Content-Type: application/json" -X PUT -d '{"name":"json","surname":"gson","married":true,"age":32,"salary":123,"hasCar":true,"childs":["serkan","volkan","aybars"]}' XXXXXX/ponyo/UserModel/json

I resolved it by adding the dependency to pom.xml as follows. Please try it.

    <dependency>
        <groupId>com.owlike</groupId>
        <artifactId>genson</artifactId>
        <version>0.98</version>
    </dependency>

I get the same issue. In fact, the request didn't reach the jersey annoted method. I solved the problem with add the annotation: @Consumes(MediaType.APPLICATION_FORM_URLENCODED) The annotation @Consumes("/") don't work!

    @Path("/"+PropertiesHabilitation.KEY_EstNouvelleGH)
    @POST
    //@Consumes("*/*")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public void  get__EstNouvelleGH( @Context HttpServletResponse response) {
        ...
    }

Don't return Strings in your methods but Customer objects it self and let JAXB take care of the de/serialization.

---

I had the same issue, as it was giving error-415-unsupported-media-type while hitting post call using json while i already had the

@Consumes(MediaType.APPLICATION_JSON) 

and request headers as in my restful web service using Jersey 2.0+

Accept:application/json
Content-Type:application/json

I resolved this issue by adding following dependencies to my project

<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.25</version>
</dependency>

this will add following jars to your library :

1. jersey-media-json-jackson-2.25.jar
2. jersey-entity-filtering-2.25.jar
3. jackson-module-jaxb-annotations-2.8.4.jar
4. jackson-jaxrs-json-provider-2.8.4.jar
5. jackson-jaxrs-base-2.8.4.jar

I hope it will works for others too as it did for me.

just change the content-type to application/json when you use JSON with POST/PUT, etc...

---

In case you are trying to use ARC app from google and post a XML and you are getting this error, then try changing the body content type to application/xml. Example here
