我如何将soap api响应发送到数据库中的某些字段

Question

如何使用java解析数据字段并将其发送到db。 我需要将数据存储到数据库的代码。 它需要任何额外的依赖项。

上面是示例格式如何解析和获取一些字段名称和 isbn，更多的价格如何发送到 db。

Answer 1

您可以使用用于 XML 处理的内置Java API（称为 DOM XML Parser）来提取每个数据。 它将 XML 文件变成 DOM 或 Tree 结构，你必须一个节点一个节点地遍历才能得到你想要的。 这是一个示例，展示了如何做到这一点，

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

try {
     // Creating a constructor of file class and parsing an XML file
     File file = new File("XMLFile.xml");
     // An instance of factory that gives a document builder
     DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
     // An instance of builder to parse the specified XML file
     DocumentBuilder db = dbf.newDocumentBuilder();
     Document doc = db.parse(file);
     doc.getDocumentElement().normalize();
     System.out.println("Root element: " + doc.getDocumentElement().getNodeName());
     NodeList nodeList = doc.getElementsByTagName("product");

     // NodeList is not iterable, so we are using for loop
     for (int i = 0; i < nodeList.getLength(); i++) {
         Node node = nodeList.item(i);
         System.out.println("\nNode Name :" + node.getNodeName());
         if (node.getNodeType() == Node.ELEMENT_NODE) {
             Element eElement = (Element) node;
             System.out.println("PUB ID: " + eElement.getElementsByTagName("PUB_ID").item(0).getTextContent());
             System.out.println("LOG NO: " + eElement.getElementsByTagName("LOG_NO").item(0).getTextContent());
             System.out.println("PIN NO: " + eElement.getElementsByTagName("PIN_NO").item(0).getTextContent());
             System.out.println("SERIES CODE: " + eElement.getElementsByTagName("SERIES_CODE").item(0).getTextContent());
             System.out.println("SERIES DESC: " + eElement.getElementsByTagName("SERIES_DESC").item(0).getTextContent());
         }
     }
 } catch (SAXException | IOException | ParserConfigurationException ex) {
     Logger.getLogger(YourClass.class.getName()).log(Level.SEVERE, null, ex);
 }

然后您可以编写一个插入查询来将数据发送到您的数据库。

希望这对你有帮助！
