在不使用JAX-RS的情況下調用Web服務

我有一個Restfull Jax-rs的Web服務，我創建了帶Restfull的WSClient，但未使用Jax-rs。我正在使用Spring3.0，Tomcat。這裏是我的WSClient：在不使用JAX-RS的情況下調用Web服務

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; 
    } 
}

但是當我嘗試調用Web服務使用此代碼我收到錯誤，如：

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

我完全被困在這兒了，請幫我，我應該怎麼在我的代碼中進行更改...

它看起來像你正在努力反序列化XML到一個類。你得到的xml是什麼樣的？ –

@ nicholas.hauschild感謝您的重播，這裏我在答題部分添加了我的xml ...請檢查它。 – Balasaheb

嗨，這裏我能夠找出解決方案現在它的工作，當我使用webClient。我的控制器斬件如：

@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; 
    }
