我有一个带有Restfull Jax-rs的Web服务，我用Restfull创建了WSClient但没有使用Jax-rs。我使用的是Spring3.0，Tomcat。 这是我的WSClient：
import javax.inject.Inject;
import javax.inject.Named;
import org.apache.cxf.jaxrs.client.JAXRSClientFactory;
import org.apache.cxf.jaxrs.client.WebClient;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.client.RestTemplate;
@Controller
public class WSClientController {
@Inject
@Named("restTemplate")
protected RestTemplate restTemplate;
private final static String articleServiceUrl = "http://HOST:8080/WS/Service/getAccounts.html";
@RequestMapping(value={"/accountMasterRoot"}, method={org.springframework.web.bind.annotation.RequestMethod.GET}, headers={"Accept=application/xml, application/json"})
public List<AccountMasterWS> getAccountMasterRoot() {
try {
AccountMasterRoot ac = restTemplate.getForObject(articleServiceUrl, AccountMasterRoot.class);
List<AccountMasterWS> listAccounts = ac.getAccountMasterWS();
return listAccounts;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
但是当我尝试使用此代码调用Web服务时，我收到的错误如下：
org.springframework.http.converter.HttpMessageNotReadableException: Could not read [class com.nmmc.fas.ws.model.AccountMasterRoot]; nested exception is org.springframework.oxm.UnmarshallingFailureException: XStream unmarshalling exception; nested exception is com.thoughtworks.xstream.mapper.CannotResolveClassException: accountMasterRoot : accountMasterRoot

您好，我在使用webClient时能够找到解决方案。 我的控制器剪断了：
@RequestMapping(value = { "/accountMasterRoot.etenderingWS" }, method = { org.springframework.web.bind.annotation.RequestMethod.GET })
public List<AccountMasterWS> getAccountMasterRoot() {
try {
WebClient client = WebClient.create(articleServiceUrl);
AccountMasterRoot a = client.accept("application/xml").get(
AccountMasterRoot.class);
List<AccountMasterWS> wsl = a.getAccountMasterWS();
for (int i = 0; i < wsl.size(); i++) {
Long code = wsl.get(i).getCode();
String name = wsl.get(i).getName();
System.out.println("Code " + code + " name " + name);
}
System.out.println("End of WebService");
return wsl;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
