Question

在我的应用程序中，我使用库浏览器和Apache CXF来实现REST调用。特别是，我创建了我的DTO，服务和dao，通过put方法将记录插入数据库。

下面的代码是有效的，但我的问题是当确定传递DTO列表时客户端报告错误：

/* Client Rest */
WebResource service = clientJersey.get().resource(this.baseURI);        
GaraDTO garaDTO = new GaraDTO();
garaDTO.setVersion("0");
..........................
ClientResponse response = service.path("rest").path("gare").accept(this.mediaType).put(ClientResponse.class, garaDTO);

/* DTO */
@XmlRootElement(name = "gara")
public class GaraDTO {

private Integer version;
. . . . . . . . . . . .
public GaraDTO(){
}

@XmlElement
public Integer getVersion() {
return version;
}
public void setVersion(Integer version) {
this.version = version;
}
. . . . . . . . . . . .
}


/* Service */
@Override
@PUT
@Consumes(MediaType.APPLICATION_XML)
public void putInsert(GaraDTO garaDto){
....................
//insert DB
....................
}

如果在创建了DTO的ArrayList之后，将此列表移到客户端，我会收到错误。

List<GaraDTO> listGaraDTO = new ArrayList();
listGaraDTO.add(garaDTO1);
listGaraDTO.add(garaDTO2);
.............................. 
ClientResponse response = service.path("rest").path("gare").accept(this.mediaType).put(ClientResponse.class, listGaraDTO);

如何传递DTO列表？

感谢

Answer 1

如果您希望您的API接受List，您需要让它实际接受List，而不是单个GaraDTO。

//客户端

package com.project.rest.model;

import java.util.HashSet;
import java.util.Set;

public class Client {

    private Long id;
    private String email;
    private String lang;

    public Client() {
    }

    public Client(Long id) {
    this.id = id;
    }

    public Client(Long id, String email, String lang) {
    this.id = id;
    this.email = email;
    this.lang = lang;
    }

    public Long getId() {
    return id;
    }

    public void setId(Long id) {
    this.id = id;
    }

    public String getEmail() {
    return email;
    }

    public void setEmail(String email) {
    this.email = email;
    }

    public String getLang() {
    return lang;
    }

    public void setLang(String lang) {
    this.lang = lang;
    }


    @Override
    public String toString() {
    return "Client [id=" + id + ", email=" + email + ", lang=" + lang + "]";
    }

}

// ClientService

package com.project.rest;

import java.util.List;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import com.project.rest.model.Client;

@Path("/client")
public class ClientService {

    @POST
    @Path("/sendList")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response consumeJSONList(List<Client> clientList) {

        String output = "consumeJSONList Client : " + clientList.toString() + "\n\n";

        return Response.status(200).entity(output).build();
    }

}

// JerseyClient

package com.project.rest;

import java.util.ArrayList;
import java.util.List;

import javax.ws.rs.core.MediaType;

import com.project.rest.model.Client;
import com.project.rest.model.Device;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.config.ClientConfig;
import com.sun.jersey.api.client.config.DefaultClientConfig;
import com.sun.jersey.api.json.JSONConfiguration;

public class JerseyClient {

public static void main(String[] args) {

try {

    List<Client> clientList = new ArrayList<Client>();
    clientList.add(new Client(1L, "pruebas@pruebas.com", "es"));
    clientList.add(new Client(2L, "pruebas@pruebas.com", "es"));
    clientList.add(new Client(3L, "pruebas@pruebas.com", "es"));

    ClientConfig clientConfig = new DefaultClientConfig();

    clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);

    com.sun.jersey.api.client.Client c = com.sun.jersey.api.client.Client.create(clientConfig);

    WebResource webResource = c.resource("http://localhost:8080/project_rest/rest/client/sendList");

    ClientResponse response = webResource.accept("application/json").type("application/json").post(ClientResponse.class, clientList);

    if (response.getStatus() != 200) {
    throw new RuntimeException("Failed sendClientList: HTTP error code : " + response.getStatus());
    }

    String output = response.getEntity(String.class);

    System.out.println("sendClientList... Server response .... \n");
    System.out.println(output);

} catch (Exception e) {

    e.printStackTrace();

}
}
}
