Web服務響應返回<item xsi：nil =「true」xmlns：xsi =「http://www.w3.org/2001/XMLSchema-instance」/>

我對Web服務非常陌生。我正在創建Apache CXF（apache-cxf-2.5.0）基於SOAP的Web服務。它從Java類創建WSDL（Java第一種方法）。Web服務響應返回<item xsi：nil =「true」xmlns：xsi =「http://www.w3.org/2001/XMLSchema-instance」/>

以下是我的Java類：

package com.abcd.shoppingcart; 

import java.sql.Connection; 
import java.sql.ResultSet; 
import java.sql.Statement; 

import javax.jws.WebService; 

import org.jboss.wsf.spi.annotation.WebContext; 

import com.abcd.db.DBConnection; 

@WebService(endpointInterface = "com.abcd.shoppingcart.GetMerchantsCardsListInterface", serviceName = "GetMerchantsCardsList4") 
@WebContext(contextRoot = "/" , urlPattern="/SrvGetmerchantsCardsList.jsp") 
public class GetMerchantsCardsList4 implements GetMerchantsCardsListInterface { 
    private DBConnection dbConnection; 

    private Connection con = null; 
    private Statement stmt = null; 
    private ResultSet rset = null; 

    private String sqlSelect = null; 

    String[][] cardData = null; 
    int columnNo = 1, rowNo = 1, totalRows = 0, totalColumns = 6; 

    public String[][] returnMerchantsCardsList(int pageNumber, int recordsPerPage) { 
     dbConnection = new DBConnection(); 
     sqlSelect = "SELECT " 
       + " giftcard.MerchantId, giftcard.MerchantName, giftcard.ID AS GiftCardId, giftcardtransactions.CardNumber AS GiftCardNumber, " 
       + " giftcardtransactions.CardValue, giftcardtransactions.ImageName " 
       + " FROM merchant " 
       + " INNER JOIN giftcard ON giftcard.MerchantId = merchant.ID " 
       + " INNER JOIN giftcardtransactions ON giftcardtransactions.id = merchant.ID " 
       + " WHERE merchant.isActive = '1' " 
       + " GROUP BY giftcard.MerchantId"; 

     try { 
      con = dbConnection.getConnection(); 
      stmt = con.createStatement(); 

      rset = stmt.executeQuery(sqlSelect); 

      rset.last(); 
      totalRows = rset.getRow(); 

      totalRows++; 
      totalColumns++; 

      cardData = new String[totalRows][totalColumns]; 

      rset.beforeFirst(); 

      while (rset.next()) { 
       columnNo = 1; 
       while (columnNo < totalColumns) { 
        cardData[rowNo][columnNo] = rset.getString(columnNo); 
        //System.out.print(cardData[rowNo][columnNo] + "\t\t"); 
        columnNo++; 
       } 
       rowNo++; 
       System.out.println(); 
      } 

      rset.close(); 
      stmt.close(); 
      con.close(); 
     } catch (Exception e) { 
      System.out.println(e.getMessage()); 
     } finally { 
     } 

     return cardData; 
    } 
}

這是在指定的URL創建WSDL：

我使用的soapUI進行測試。這是生成的請求時，我使用的soapUI：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:shop="http://shoppingcart.abcd.com/"> 
    <soapenv:Header/> 
    <soapenv:Body><shop:returnMerchantsCardsList> 
     <pageNumber>1</pageNumber> 
     <recordsPerPage>4</recordsPerPage> 
     </shop:returnMerchantsCardsList> 
    </soapenv:Body> 
</soapenv:Envelope>

這是我收到的時候我請求提交到指定端點URL首次迴應：

其實我期待同樣的反應，當我提出第一次請求。但不知怎的，每次我提交請求時，我都會得到上面的回覆，但沒有任何數據。如何擺脫這一點？

謝謝。

我的問題或多或少得到解決。問題出在我的Java類中，其中有類級變量。我改變了它，並使其成爲方法級變量，現在我得到了預期的結果。謝謝。 – waprau

我的問題解決了。問題是變量，對象被聲明的地方。早些時候，我在課堂上宣佈了這些變量，對象。我更改並聲明瞭方法中的變量和對象，並且它工作正常。

謝謝。

如果您願意，您可以將自己的答案標記爲「已回答」並獲得一些積分。 – xpda

@xpda：當然，我會這樣做的。我想我必須等到明天，直到我點擊接受答案時，我纔會收到消息 - 「明天你可以接受你自己的答案」。謝謝。 – waprau

Web服務響應返回<item xsi：nil =「true」xmlns：xsi =「http://www.w3.org/2001/XMLSchema-instance」/>
