解析方法

go 复制代码

public static List<PlatJuMinBaoXian> parse(String xmlString) {
        List<PlatJuMinBaoXian> result = new ArrayList<>();
        try {
            // 创建 DocumentBuilder
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();

            // 将字符串转换为输入流
            ByteArrayInputStream input = new ByteArrayInputStream(xmlString.getBytes("UTF-8"));

            // 解析 XML
            Document document = builder.parse(input);
            document.getDocumentElement().normalize();

            // 获取所有 <r> 标签
            NodeList nodeList = document.getElementsByTagName("r");

            // 遍历每个 <r> 标签
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node node = nodeList.item(i);
                if (node.getNodeType() == Node.ELEMENT_NODE) {
                    Element element = (Element) node;

                    // 创建 PlatJuMinBaoXian 对象
                    PlatJuMinBaoXian platJuMinBaoXian = new PlatJuMinBaoXian();
                    platJuMinBaoXian.setJfxmbh(element.getAttribute("jfxmbh"));
                    platJuMinBaoXian.setZznf(element.getAttribute("zznf"));
                    platJuMinBaoXian.setQsnf(element.getAttribute("qsnf"));
                    platJuMinBaoXian.setJfxmmc(element.getAttribute("jfxmmc"));
                    platJuMinBaoXian.setJfxmje(element.getAttribute("jfxmje"));
                    platJuMinBaoXian.setJfrq(element.getAttribute("jfrq"));

                    // 添加到结果列表
                    result.add(platJuMinBaoXian);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

实体类

go 复制代码

@Data
public class PlatJuMinBaoXian {
    //起始年月
    private String qsnf;
    //终止年月
    private String zznf;
    //缴费项目编号
    private String jfxmbh;
    //缴费项目名称
    private String jfxmmc ;
    //缴费金额
    private String jfxmje;
    //缴费日期
    private String jfrq;

}

测试

go 复制代码

public static void main(String[] args) {
      
        String xmlString = "<root>" +
                "<r jfxmbh=\"C11\" zznf=\"2023\" qsnf=\"2023\" jfxmmc=\"普通个人缴费\" jfxmje=\"350.00000000\" jfrq=\"20230220\" />" +
                "<r jfxmbh=\"C41\" zznf=\"2023\" qsnf=\"2023\" jfxmmc=\"缴费补贴\" jfxmje=\"30.00000000\" jfrq=\"20230220\" />" +
                "</root>";
        String xmlStringNew = "<r jfxmbh=\"C11\" zznf=\"2023\" qsnf=\"2023\" jfxmmc=\"普通个人缴费\" jfxmje=\"350.00000000\" jfrq=\"20230220\" /><r jfxmbh=\"C41\" zznf=\"2023\" qsnf=\"2023\" jfxmmc=\"缴费补贴\" jfxmje=\"30.00000000\" jfrq=\"20230220\" />";
        String endXml = "<root>" + xmlStringNew + "</root>";

        List<PlatJuMinBaoXian> result = parse(endXml);
        result.forEach(System.out::println);
      
    }
