java – Glassfish：Jersy客户端中的MessageBodyProviderNotFoundException

嗨所有我试图从头开始创建一个休息网络服务.这是我的服务部分

@Path("/Phones")
public class PhonessResource {

 @GET
 @Produces({MediaType.APPLICATION_XML,MediaType.APPLICATION_JSON})
  public Response getAllNumbers(){
      List<PhoneDetail> list = PhoneDirectoryDao.getInstance().getAllNumbers();
      GenericEntity<List<PhoneDetail>> entity = new GenericEntity<List<PhoneDetail>>(list) {};
      Response response =Response.ok(entity).status(200).build();
      return response;//PhoneDirectoryDao.getInstance().getAllNumbers();
    }
 }

我的数据模型：我有我的getter和setter以及另一个带有所有属性的构造函数,我没有将它粘贴到更少的问题长度,我在客户端和服务器中使用相同的数据模型

@XmlRootElement(name="PhoneDetail")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder={"id","firstName","lastName","address","phoneNo","timeStamp"})
public class PhoneDetail {

    private int id;
    private String firstName;
    private String lastName;
    private String address;
    private String phoneNo;
    private Timestamp timeStamp;

    public PhoneDetail() {}
}

然后我创建一个java客户端来测试服务.我正在使用NETBEANS IDE,所以我在IDE中选择默认选项来创建它

因此我创建了一个Jersey客户端

public class PhoneCLient {
    private WebTarget webTarget;
    private Client client;
    private static final String BASE_URI = "http://localhost:8080/Phones/webresources";

    public PhoneCLient() {
        client = javax.ws.rs.client.ClientBuilder.newClient();
        webTarget = client.target(BASE_URI).path("Items");
    }


    public <T> T getAllNumbers_XML(Class<T> responseType) throws ClientErrorException {
        WebTarget resource = webTarget;
        return resource.request(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
    }

    public <T> T getAllNumbers_JSON(Class<T> responseType) throws ClientErrorException {
        WebTarget resource = webTarget;
        return resource.request(javax.ws.rs.core.MediaType.APPLICATION_JSON).get(responseType);
    }
}

但它给了我这个错误

Exception in thread "main" org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException: MessageBodyReader not found for media type=application/xml, type=class org.glassfish.jersey.client.ClientResponse, genericType=class org.glassfish.jersey.client.ClientResponse.

但是当我在浏览器或RestClient Browser插件中测试服务时,它工作正常.
 谁能告诉我出了什么问题？

解决方法:

对于Xml,如果你拥有J​​ersey附带的所有依赖项,它应该可以解决客户端API的问题.您可能没有添加所有这些.我发现你没有使用Maven,我强烈建议你这样做.但我会提供两种方法来处理这个问题.

XML

Maven的：

只有您需要启动并运行客户端的依赖项(支持JAXB xml)

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.13</version>
</dependency>

没有简单得多:-)

非Maven的：

因此,使用Maven项目,我添加了上面的依赖项,这些都是它所引入的传递依赖项.在非Maven项目中,您需要手动添加所有这些jar.

如果你转到Jersey Hompage,请转到下载,并下载“Jersey JAX-RS 2.0 RI软件包.你应该在那里找到所有这些依赖项.你应该将所有需要的东西添加到你的项目中

注意：Netbeans已经附带了Jersey 2.0(JAX-RS RI)库.您只需将该库添加到项目中即可.只需右键单击项目中的[Libraries]节点,然后选择[Add Library].您应该在对话框中看到Jersey.这个解决方案可能是最简单的,但它将导入所有Jersey依赖项,超过客户端API所需的

JSON

JSON需要另一个依赖项：

Maven的：

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-moxy</artifactId>
    <version>2.13</version>
</dependency>

非Maven的

请查看this post的图像和进一步说明.

只是在类路径上有这些依赖项应该可以工作,没有任何特殊配置.
