我正在使用带有Jersey和Tomcat的JAX-RS Web应用程序。发布请求很好但是当我尝试使用JSON数据时，我得到一个HTTP状态415 - 不支持的媒体类型。

这是我的代码：

package com.sms.presentationT;
import java.io.Serializable;
import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;

import org.json.simple.parser.ParseException;

@Path("/user-servicesLogincheck1")
public class Check implements Serializable{

    /**

    private static final long serialVersionUID = 1L;
    @POST
    @Path("/LoginPagecheck1")
    //@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    @Consumes(MediaType.APPLICATION_JSON)
    //@Produces("application/json")
    @Produces(MediaType.APPLICATION_JSON)
    public Regitration loginUserInfo(@FormParam("logusertype") String logUserType, @FormParam("userNAME") String UserNAME,*emphasized text* @FormParam("PassWORD") String PAssWORD) throws ParseException
    {

        System.out.println(logUserType+UserNAME+PAssWORD);

        LoginUserServiceCheck LUS = new LoginUserServiceCheck();
        JSONObject jobj2 = new JSONObject();
        jobj2 = LUS.LoginInputDatacheck(logUserType,UserNAME, PAssWORD);

        System.out.println("ssssssssssssssssssssssssssss");

        System.out.println("Presentation jobj"+jobj2);


        String jsonText = jobj2.toJSONString();
        System.out.println(jsonText);

        JSONParser parser = new JSONParser();

        JSONObject newJObject = null;

        try {
            newJObject = (JSONObject) parser.parse(jsonText);
        } catch (ParseException e) {
            e.printStackTrace();
        }

        //System.out.println(LUS.loginresponse);
        //System.out.println(LUS.resultStatus);
        /*
        if(LUS.resultStatus)
        { 
            System.out.println(LUS.loginresponse);


            return LUS.loginresponse;
            //return "UserName is valid";
        }
        else
        {
            return LUS.loginresponse;
        }

        */

        System.out.println(newJObject.get("Name"));
        System.out.println(newJObject.get("Email"));

        Regitration rg = new Regitration();

        rg.setUserType(logUserType);
        rg.setName((String)newJObject.get("Name"));
        rg.setEmail((String)newJObject.get("Email"));
        rg.setUserName((String)newJObject.get("userName"));
        rg.setPassword((String)newJObject.get("password"));
        rg.setConfirmPasssword((String)newJObject.get("password"));
        rg.setBirthDay((String)newJObject.get("birthday"));
        rg.setGender((String)newJObject.get("Gender"));
        rg.setMobileNo((String)newJObject.get("mobileNo"));
        rg.setCurrentAddress((String)newJObject.get("currentAddress"));

        rg.setPermenantAddress((String)newJObject.get("PermenantAddress"));
        rg.setCountry((String)newJObject.get("Country"));
        rg.setState((String)newJObject.get("state"));
        rg.setCity((String)newJObject.get("City"));

        rg.setLandmark((String)newJObject.get("Landmark"));
        rg.setZipCode((String)newJObject.get("ZipCode"));
        return rg;
    }

}

我想指出你不使用java命名约定。

您的REST端点需要表单数据，但您已指出它使用JSON。 您应该让REST端点使用表单数据，即 @Consumes（MediaType.APPLICATION_FORM_URLENCODED） 或者，您可以将 FormParam 方法参数更改为与您的JSON对象或String参数匹配的POJO，然后将您的JSON字符串反序列化为POJO。
