错误服务Rest Client-Java Rest Client-日食

Question

当前，我在使用JAVA REST JSON服务时遇到错误，它没有启动CoinsalesService服务类，下面的行保留了服务代码，Servlet和Tomcat 8.5日志。

服务客户端

package com.coinsales.sw.rest.services;

    import java.util.List;

    import javax.ws.rs.client.ClientBuilder;
    import javax.ws.rs.client.WebTarget;
    import javax.ws.rs.core.MediaType;

    import com.coinsales.sw.rest.beans.CoinsalesBean;
    import com.coinsales.sw.rest.models.Coinsales;

    public class CoinsalesService {
        private static final String URL_GET_ALL_COINSALE = "http://localhost:8080/CoinSalesWS/apics/ShowAllCoinsales";

        private static WebTarget resource = ClientBuilder.newBuilder().build().target(URL_GET_ALL_COINSALE);

        public static List<Coinsales> fetchCoinsales(int offset, int num) {
            CoinsalesBean res = resource.queryParam("seed", 1)
                    .queryParam("results", num).queryParam("page", 1)
                    .request(MediaType.APPLICATION_JSON).get(CoinsalesBean.class);
            return res.getResults();
        }   


    }

Servlet

private void mostrar(HttpServletRequest request, HttpServletResponse response) throws SQLException, IOException , ServletException{

        response.setContentType("text/html;charset=UTF-8");

        List<Coinsales> coinsales = CoinsalesService.fetchCoinsales(0, 50);

        request.setAttribute("coinsales", coinsales);

        request.getRequestDispatcher("/view/coinsales/index.jsp").forward(request, response);

    }

Tomcat 8.5
