Question

我的代码

/*

package beans;

import clients.NewJerseyClient;



import entities.ReservationItem;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.ws.rs.core.GenericType;

import parameters.ReservationParam;
import  org.glassfish.jersey.client.ClientResponse;

/**
 *
 * @author subhi2
 */
@ManagedBean
@SessionScoped
public class PageController implements Serializable {

    public String moveToPage2() {

        NewJerseyClient client = new NewJerseyClient();

        ClientResponse response = client.findInsertedReservationItem(ClientResponse.class, "22", "2010-07-26T11:15:51", "2014-07-26T11:15:51");


        GenericType<List<ReservationItem>> genericType = new GenericType<List<ReservationItem>>() {
        };
// Returns an ArrayList of Players from the web service
        List<ReservationItem> data = new ArrayList<ReservationItem>();



        data = (response.getEntity(genericType));
        return data.toString();
    }
}

这条线 data =（response.getEntity（genericType））; 导致错误

此代码正在使用旧球衣，但现在我应该怎么做才能解决此错误？

Answer 1

您可以通过response.readEntity（genericType）更改response.getEntity（genericType）

Answer 2

根据你的要求，我已经取代了这个

response.getEntity(String.class);

由此

response.getEntityStream().toString();

但是可能存在与泽西岛2相关的另一个问题，我可以通过替换这些进口来实现它

import jersey.spi.container.servlet.ServletContainer;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.WebResource;

通过这些

import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.client.ClientResponse;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

并且在代码中（因为我使用的是Jetty）我不得不替换这个

servletHolder.setInitParameter("com.sun.jersey.config.property.packages", 
                               "resources");

由此

servletHolder.setInitParameter("jersey.config.server.provider.packages", 
                               "resources");

和这个

WebResource webResource = client.resource("http://url_u_want_to_connect");
ClientResponse response = webResource.accept("application/json")

由此

WebTarget webTarget = client.target("http://url_u_want_to_connect");
ClientResponse response = webTarget.request("application/json")

最后这里是“最新”文档的链接（这是关于Jersey 2.x，2013年）

jersey 2库response.getEntity不存在我应该用什么代替
