Parse Response Entity with CXF Rest client
提问by cristian370
I'm working with CXF 2.3.2, I made this REST Service:
我正在使用 CXF 2.3.2，我制作了这个 REST 服务：
Interface:
界面：
@WebMethod
@GET
@Path("/object/{id}")
@Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML, MediaType.TEXT_XML})
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML, MediaType.TEXT_XML})
public Response object(@PathParam("id") Long id);
Impl:
实施：
@Override
public Response object(Long id) {
CompanyVO company = new CompanyVO();
company.setAddress("address");
company.setFantasyName("fantasy name");
company.setFiscalId("fiscalid");
company.setGroups("groups");
return Response.ok().type(MediaType.APPLICATION_XML).entity(company).build();
}
I need to consume that service using a CXF REST Client and obtain the object Entity inside de Response as a Java Object, not as a InputStream.
我需要使用 CXF REST 客户端来使用该服务，并将 de Response 中的对象实体作为 Java 对象而不是 InputStream 获取。
I made a first implementation as follows, using a ResponseReader class to wrap my Java Class:
我做了如下的第一个实现，使用 ResponseReader 类来包装我的 Java 类：
String operation = "/object/{id}";
ResponseReader reader = new ResponseReader();
reader.setEntityClass(CompanyVO.class);
WebClient client = WebClient.create(PATH, Collections.singletonList(reader));
client.path(operation, 12L);
client.accept(MediaType.APPLICATION_XML);
client.type(MediaType.APPLICATION_XML);
//the response's entity object should be this Class.
CompanyVO company = new CompanyVO();
Response response = client.get();
//i get the entity object as a InputStream, but i need a CompanyVO.
//i made this once, but i can't see the difference.
Object entity = response.getEntity();
Maybe i made the service wrong or the client has a bad conf. i need your help, please!
也许我做错了服务或者客户有一个糟糕的 conf。我需要你的帮助，拜托！
The service is was configurated using Spring 3.0.5:
该服务是使用 Spring 3.0.5 配置的：
<jaxrs:server id="serviceAdvisorRestServer" address="/rest">
<jaxrs:serviceBeans>
<ref bean="fileService"/>
</jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="json" value="application/json"/>
<entry key="xml" value="application/xml"/>
<entry key="html" value="text/html"/>
<entry key="pdf" value="application/pdf"></entry>
</jaxrs:extensionMappings>
Thanks!
谢谢！

Instead of getting the Response object by invoking the get method on client try this:
不要通过调用客户端上的 get 方法来获取 Response 对象，试试这个：
CompanyVO company = client.get(CompanyVO.class);
I think this might be able to solve your problem.
我认为这可能可以解决您的问题。
Have a look at webclient api
看看 webclient api
Also i dont think you would need @Consumes annotation on your webservice method for application/json etc... as you are using a Path parameter in the method.
此外，我认为您不需要在应用程序/json 等的 webservice 方法上使用 @Consumes 注释......因为您在方法中使用了 Path 参数。

No clean solution here for CXF 2.3.X except switching to the usage of proxies with JAXRSClientFactory or use the double calls (get() - get(someclass.class). The webclient does' t support the reader provider.
对于 CXF 2.3.X，这里没有干净的解决方案，除了切换到使用 JAXRSClientFactory 的代理或使用双重调用 (get() - get(someclass.class)）。Web 客户端不支持读取器提供程序。
CXF 2.7.X implements JAX-RS 2.0 (almost) and from this version on you can call client.readEntity().
CXF 2.7.X 实现了 JAX-RS 2.0（几乎），从这个版本开始你可以调用 client.readEntity()。

For the Proxy APIit should work like this:
对于代理 API，它应该像这样工作：
Try:
尝试：
ResponseReader reader = new ResponseReader();
reader.setEntityClass(CompanyVO.class);
InterfaceClass proxy = JAXRSClientFactory.create(PATH, InterfaceClass.class, Collections.singletonList(reader));
Then:
然后：
Response res = proxy.get();
CompanyVO company = (CompanyVO) res.getEntity();
For the WebClientit should work quite the same:
对于WebClient，它的工作方式应该完全相同：
Try:
尝试：
ResponseReader reader = new ResponseReader();
reader.setEntityClass(CompanyVO.class);
WebClient client = WebClient.create(PATH, Collections.singletonList(reader));
Then:
然后：
Response res = client.get();
CompanyVO company = (CompanyVO) res.getEntity();
