特殊字符在將數據轉換爲xml時被替換

在我的應用程序中，我需要從HBase中提取數據並將其轉換爲XML。數據完全取自HBase，但當我們將其轉換爲XML時，所有特殊字符（如「&」）正在轉換爲「& amp」。以下是我寫的代碼：特殊字符在將數據轉換爲xml時被替換

public static String getDataFromHBase(TagReplaceTO tagReplaceTO, int organizationId, int tenantId, String outBoundName, String hbaseServer, String hbasePort) 
     throws Exception 
    { 
     Map<String, List<IntegrationTagTO>> tagMap = tagReplaceTO.getTagMap(); 
     String headTag = tagReplaceTO.getTagName(); 
     String headTagReplace = getSystemHeadTagName(headTag, tagMap); 
     String[] rootSystem = headTagReplace.split(":"); 
     String columnFamily = null; 
     int count = 0; 
     String columnNameTemp = null; 
     String columnValue = null; 
     String colVal[] = null; 
     try { 

//fetch data from Hbase 
      Configuration config = HBaseConfiguration.create(); 
      config.set("hbase.zookeeper.quorum", hbaseServer); 
      config.set("hbase.zookeeper.property.clientPort", hbasePort); 
      HTable table = new HTable(config, rootSystem[0]); 
      SingleColumnValueFilter filter = new SingleColumnValueFilter(Bytes.toBytes(rootSystem[1]), Bytes.toBytes("organizationid"), CompareFilter.CompareOp.EQUAL, 
        new BinaryComparator(Bytes.toBytes(String.valueOf(organizationId)))); 
      Scan scan = new Scan(); 
      scan.setFilter(filter); 
      ResultScanner scanner = table.getScanner(scan); 
      String collon = ":"; 
      String headNameSpace = rootSystem[0] + collon + rootSystem[1]; 
      String rootColumn = getClientFirstColumnForFirstTime(headNameSpace, tagMap); 
      String[] rootColumns = rootColumn.split(":"); 
      headNameSpace = headNameSpace + collon + rootColumns[2]; 
      DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
      DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder(); 
      Document document = documentBuilder.newDocument(); 
      Element root = document.createElement(outBoundName); 
      document.appendChild(root); 
      Element subRoot = document.createElement(rootColumns[0]); 
      root.appendChild(subRoot); 
      for (Result rr = scanner.next(); rr != null; rr = scanner.next()) { 
       Element rowElement = document.createElement(rootColumns[1]); 
       subRoot.appendChild(rowElement); 
       for (KeyValue keyValue : rr.list()) { 
        columnFamily = Bytes.toString(keyValue.getFamily()); 
        columnNameTemp = Bytes.toString(keyValue.getQualifier()); 
        columnValue = Bytes.toString(keyValue.getValue()); 
        columnValue = columnValue.trim(); 

//convert Hbase data into XML 
        String columnNameWithNameSpace = headNameSpace + collon + columnNameTemp.trim(); 
        String columnName = getClientFirstColumnForFirstTime(columnNameWithNameSpace, tagMap); 
        if (columnName != null) { 
         String splitColumn[] = columnName.split(":"); 
         if (!(columnValue.equals("\\n") || columnValue.isEmpty())) { 
          String split[] = columnValue.split("\\$"); 
          if (split.length == 1) { 
           Element leafElement = document.createElement(splitColumn[1]); 
           if (split.length == 1) { 
            leafElement.appendChild(document.createTextNode(split[0])); 
           } else { 
            leafElement.appendChild(document.createTextNode("")); 
           } 
           rowElement.appendChild(leafElement); 
          } else { 
           Element subRowElement = document.createElement(splitColumn[0]); 
           rowElement.appendChild(subRowElement); 
           for (int i = 1; i < split.length; i++) { 
            Element subSubRowElement = document.createElement(splitColumn[1]); 
            String splinIn[] = split[i].split("#"); 
            for (String str : splinIn) { 
             colVal = str.split(":"); 
             String leafColumnWithNameSpace = headNameSpace + collon + columnNameTemp + collon + splitColumn[2] + collon + colVal[0].trim(); 
             String columnLeafVal = getClientLeafColumn(leafColumnWithNameSpace, tagMap); 
             if (columnLeafVal != null) { 
              Element leafElement = document.createElement(columnLeafVal); 
              if (colVal.length == 2) { 
               leafElement.appendChild(document.createTextNode(colVal[1])); 
              } else { 
               leafElement.appendChild(document.createTextNode("")); 
              } 
              subSubRowElement.appendChild(leafElement); 
             } 
            } 
            subRowElement.appendChild(subSubRowElement); 
           } 
          } 
         } else { 
          String[] splitCol = columnName.split(":"); 
          rowElement.appendChild(document.createElement(splitCol[0])); 
         } 
        } 
       } 
      } 
      table.close(); 
      DOMSource domSource = new DOMSource(document); 
      StringWriter writer = new StringWriter(); 
      StreamResult result = new StreamResult(writer); 
      TransformerFactory tf = TransformerFactory.newInstance(); 
      Transformer transformer = tf.newTransformer(); 
      transformer.transform(domSource, result); 
      return writer.toString(); 
     } catch (Exception e) { 
      throw e; 
     } 
    }

我需要做些什麼改變來克服這個問題？

更多信息快速搜索之後，似乎一個'＆'是在XML文件非法，因此被轉換成'＆amp'。 [類似問題的答案]（https://stackoverflow.com/a/17424187/6707985）沒有Java的直接規範。 – geisterfurz007

這不是一個錯誤，它是一個功能。 – Aaron

谷歌「html轉義」 – vikingsteve

這是因爲某些字符在XML中是不允許的，所以它們被替換爲轉義實體。

當您想要XML中沒有轉義實體的原始數據時，您需要將其包裝在CDATA塊中。在w3schools.org
