Dropwizard несоответствие типа клиент

Question

Сначала немного фона, я пытаюсь создать приложение RESTfull в Eclipse, и я преподаю сам DropWizard на куски с помощью формата PDF книгу доступной здесь: https://github.com/adhulappanavar/Dropwizard/blob/master/RESTful%20Web%20Services%20with%20Dropwizard%20%5BeBook%5D.pdf

книг около двух лет из-за этого было несколько ошибок, из-за которых я столкнулся с этим, но следующая ошибка из моего класса ввода приложения (rappApplication) действительно превзошла меня.

 Exception in thread "main" java.lang.ClassCastException: org.glassfish.jersey.client.JerseyClient cannot be cast to com.sun.jersey.api.client.Client 
at edu.udel.rapp.rapp.rappApplication.run(rappApplication.java:50) 
at edu.udel.rapp.rapp.rappApplication.run(rappApplication.java:1) 
at io.dropwizard.cli.EnvironmentCommand.run(EnvironmentCommand.java:43) 
at io.dropwizard.cli.ConfiguredCommand.run(ConfiguredCommand.java:85) 
at io.dropwizard.cli.Cli.run(Cli.java:75) 
at io.dropwizard.Application.run(Application.java:79) 
at edu.udel.rapp.rapp.rappApplication.main(rappApplication.java:31) 

В этом классе:

import io.dropwizard.Application; 
import io.dropwizard.setup.Bootstrap; 
import io.dropwizard.setup.Environment; 

import org.skife.jdbi.v2.DBI; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 

import io.dropwizard.Application; 
import io.dropwizard.Configuration; 
import io.dropwizard.client.JerseyClientBuilder; 

import io.dropwizard.jdbi.DBIFactory; 
import edu.udel.rapp.resources.ClientResource; 
import edu.udel.rapp.resources.StudentResource; 

import com.sun.jersey.api.client.Client; 



public class rappApplication extends Application<rappConfiguration> { 
private static final Logger LOGGER = 
     LoggerFactory.getLogger(rappApplication.class); 

public static void main(final String[] args) throws Exception { 
    new rappApplication().run(args); 
} 

@Override 
public String getName() { 
    return "rapp"; 
} 

@Override 
public void initialize(final Bootstrap<rappConfiguration> bootstrap) { 
    // TODO: application initialization 
} 




@Override 
public void run(rappConfiguration c, Environment e) throws Exception { 

    final Client client = new JerseyClientBuilder(e).build("REST Client"); 
    e.jersey().register(new ClientResource(client)); 


    LOGGER.info("Method App#run() called"); 
    for (int i=0; i < c.getMessageRepetitions(); i++) { 
    System.out.println(c.getMessage()); 
} 
System.out.println(c.getAdditionalMessage()); 
// Create a DBI factory and build a JDBI instance 
final DBIFactory factory = new DBIFactory(); 
final DBI jdbi = factory.build(e, c.getDataSourceFactory(), "mysql"); 
// Add the resource to the environment 
e.jersey().register(new StudentResource(jdbi, e.getValidator())); 
} 






} 

Теперь в книге инициализации клиента в моем методе выполнения не требуют литья Клиенту, но Eclipse, дает мне ошибку компиляции (» Тип несоответствия: невозможно преобразовать из javax.ws.rs.client.Client в com.sun.jersey.api.client.Client "), если я не отсылаю к клиенту там ... который затем вызывает ошибку во время выполнения.

Кроме того, я смущен, почему у Eclipse возникает проблема с «org.glassfish.jersey.client.JerseyClient», когда то, что я импортировал для моего класса, было io.dropwizard.client.JerseyClientBuilder;

Это почти похоже на то, что Eclipse смущен относительно того, что на самом деле является Клиентом.

Answer 1

В коде here,

new JerseyClientBuilder(e).build("REST Client"); 

возвращение s экземпляр типа javax.ws.rs.client.Client. Но вы импортировали com.sun.jersey.api.client.Client в свой код.

Заменить

импорта com.sun.jersey.api.client.Client;

с

импорта javax.ws.rs.client.Client
