HTTP状态415-将数据从ajax作为json传递到restfull服务器时出现不受支持的媒体类型错误

Question

I am trying to send data with ajax as json to restful service. But something is not done right. I get this error

I read that that's maybe because I didn't add some jar files, so this are the files that I have:

My ajax function looks like this:

var url1 = "../web.projekat/rest/korisnici/registracija";

    $('#btnReg').click(function(){

            var memail = document.getElementById('email').value;
            var mkorIme = document.getElementById('korIme').value;
            var mpass = document.getElementById('pass1').value;


            $.ajax({
                type : 'POST',
                url : url1,
                contentType : 'application/json;charset=utf-8',
                dataType : "text",
                data : formToJSON(mkorIme, mpass, "ds", "dsdsd", "Menadzer",  "06315487", memail, "dsds"), 
                success : function(){
                    alert("Success");
                },

                error : function(){
                    alert("Error");
                }
            });
    });
});


function formToJSON(korIme, lozinka, ime, prezime, uloga, telefon, email, slika) {
    return JSON.stringify({
        "korIme" : korIme,
        "lozinka": lozinka,
        "ime": ime,
        "prezime": prezime,
        "uloga": uloga,
        "telefon": telefon,
        "email" : email,
        "slika": slika,
    });
}

My html file with the form looks like this:

<form action="../web.projekat/rest/korisnici/registracija" id="regForm" method="post">
        <div class="form_container">

            <div id="email_div">
                <input type="text" id="email" placeholder="Email adresa">
                <span class="error">Unesite validnu email adresu.</span>
            </div>

            <div id="korIme_div">
                <input id="korIme" type="text" placeholder="Korisnicko ime"> 
                <span class="error">Unesite korisnicko ime.</span>
            </div>

            <div id="pass1_div">
                <input id="pass1" type="password" placeholder="Lozinka">
                <span class="error">Unesite lozinku.</span>
            </div>

            <div id="pass2_div">
                <input id="pass2" type="password" placeholder="Ponovite lozinku">
                <span class="error">Unesite lozinku ponovo.</span>
            </div>

            <input id="btnReg" type="submit" value="Registruj se">

            <p>Vec ste registrovani? <a href="prijava">Prijavite se.</a></p>
        </div>
    </form>

And my web.xml looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
id="WebApp_ID" version="2.5">
  <display-name>web.projekat</display-name>
  <welcome-file-list>
    <welcome-file>html/registration_form.html</welcome-file>
  </welcome-file-list>
  <servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>controller</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
</web-app>

And finally my rest service class looks like this:

@Path("/korisnici")
public class KorisnikServis {

    @Context
    HttpServletRequest request;
    @Context
    ServletContext ctx;

    @POST
    @Path("/registracija")
    @Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
    @Produces(MediaType.TEXT_PLAIN)
    public String registracija(Korisnik data) {
        return "sdasd";
    }
}

Nothing is returned while the argument is Korisnik data , when I change it to String data it returning the data.

My Korisnik class has all the parameters and condtructors and getters and setters.

So why can't my application recognize the data that's sent ass json? It is returning the HTTP Status 415 - Unsupported Media Type error. Thank you for your help.

UPDATE

My Korisnik class code

public class Korisnik {
    public String kor_ime;
    public String lozinka;
    public String ime;
    public String prezime;
    public String uloga;
    public String telefon;
    public String email;
    public String slika;

    public Korisnik(){}

    public Korisnik(String kor_ime, String lozinka, String ime, String prezime, String uloga, String telefon, String email,
            String slika) {
        super();
        this.kor_ime = kor_ime;
        this.lozinka = lozinka;
        this.ime = ime;
        this.prezime = prezime;
        this.uloga = uloga;
        this.telefon = telefon;
        this.email = email;
        this.slika = slika;
    }

    public String getKor_ime() {
        return kor_ime;
    }

    public void setKor_ime(String kor_ime) {
        this.kor_ime = kor_ime;
    }

    public String getLozinka() {
        return lozinka;
    }

    public void setLozinka(String lozinka) {
        this.lozinka = lozinka;
    }

    public String getIme() {
        return ime;
    }

    public void setIme(String ime) {
        this.ime = ime;
    }

    public String getPrezime() {
        return prezime;
    }

    public void setPrezime(String prezime) {
        this.prezime = prezime;
    }

    public String getUloga() {
        return uloga;
    }

    public void setUloga(String uloga) {
        this.uloga = uloga;
    }

    public String getTelefon() {
        return telefon;
    }

    public void setTelefon(String telefon) {
        this.telefon = telefon;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getSlika() {
        return slika;
    }

    public void setSlika(String slika) {
        this.slika = slika;
    }

    @Override
    public String toString() {
        return "Korisnik [kor_ime=" + kor_ime + ", ime=" + ime + ", prezime=" + prezime + "]";
    }
}

Answer 1

In your AJAX request, you are specifying your dataType as text, which is why your web service is only accepting a String. Change your dataType to application/json .

EDIT:

This actually is wrong, you would probably be seeing a different error. You should try setting your contentType in your AJAX request to be just application/json (remove ;charset=utf-8 ).
