org.jboss.resteasy.client.ClientResponseFailure：無法找到內容類型為文本/純文本且類型為類java.lang.String的MessageBodyReader

請協助解決問題

提供商應用：

@Path("/payment")
public class PaymetResource {

    Object object=null;
    @Path("{type}/{gateWay}")

    public Object getResource(@PathParam("type") String type){

        if(type.equals("creditCard"))
            object = new CreditCardPaymentResource();


        if(type.equals("debitCard"))
            object = new DebitCardPaymentResource();


        return object;
    }
}

public class CreditCardPaymentResource {

    /*
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String processPayments(){
        return "hi boss";
    }*/

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public Response processPayment(@QueryParam("cardNo") String cardNo,@PathParam("gateWay") String gateWay){
        String result="processed payment with Gateway:"+gateWay+" and cardNo :"+cardNo;
        return Response.status(201).entity(result).build();
        //return "processed payment with Gateway:"+gateWay+" and cardNo :"+cardNo;
    }


}

public class DebitCardPaymentResource {


    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String processPayment(@QueryParam("cardNo") String cardNo,@PathParam("gateWay") String gateWay,@QueryParam("pin") String pin){
        return "processed payment with Gateway:"+gateWay+" and cardNo :"+cardNo+"pin No"+pin;
    }

}

客戶端應用程序：

public class RestFirstClient{


    public static void main(String[] args) {
        try{

            ClientRequest request = new ClientRequest("http://localhost:8081/DynamicDispatch/rest/payment/creditCard/HDFC");
            request.accept("text/plain");
            request.queryParameter("cardNo", "669888554");
            ClientResponse<String> response = request.get(String.class);
            System.out.println(response.getEntity().toString());
        }catch (Exception e) {
            e.printStackTrace();
        }
    }
}

當我們通過url訪問服務時，我的程序運行正常。 請幫我

網址： http：// localhost：8081 / DynamicDispatch / rest / payment / creditCard / HDFC？cardNo = 99809990876

輸出：使用網關：HDFC和卡處理付款：99809990876

內容類型文本/純文本和類型類java.lang.String的組合由在resteasy-core中找到的org.jboss.resteasy.plugins.providers.StringTextStar處理。

客戶端的創建方式如下：

final ResteasyClient client =
    new ResteasyClientBuilderImpl() //
        .connectTimeout(10, SECONDS) //
        .readTimeout(10, SECONDS) //
        .connectionCheckoutTimeout(10, SECONDS) //
        .register(new StringTextStar()) //
        .build();

final ResteasyWebTarget target = client.target(UriBuilder.fromPath("whatever path"));
final CreditCardPaymentResource client = target.proxy(CreditCardPaymentResource.class);
