Tags: /Java/   Date Created:
有如下xml：
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <pdf_report_data>
  3.   <info>AA1334</info>
  4.   <reportData>
  5.    <name>demo</name>
  6.    <address>demo address</address>
  7.    <telno>12345678</telno>
  8.   </reportData>
  9.   <reportData>
  10.    <name>demo</name>
  11.    <address>demo address</address>
  12.    <telno>12345678</telno>
  13.   </reportData>
  14.   <reportData>
  15.    <name>demo</name>
  16.    <address>demo address</address>
  17.    <telno>12345678</telno>
  18.   </reportData>
  19. </pdf_report_data>
如何定义 JAXB 实体类，以便装配的时候输出对应的 xml ？
  1. import jakarta.xml.bind.*;
  2. import java.util.ArrayList;
  3. import java.util.List;
  4. import java.io.StringWriter;
  6. @XmlAccessorType(XmlAccessType.FIELD)
  7. @XmlElement(name = "pdf_report_data")
  8. public class PdfReportData {
  9.     
  10.     @XmlElement(name = "info")
  11.     private String info;
  12.     
  13.     @XmlElement(name = "reportData")
  14.     private List<ReportData> reportDataList;
  15.     
  16.     // Constructors, getters, and setters
  17.     
  18.     public static void main(String[] args) throws JAXBException {
  19.         PdfReportData pdfReportData = new PdfReportData();
  20.         pdfReportData.setInfo("AA1334");
  22.         List<ReportData> reportDataList = new ArrayList<>();
  23.         ReportData reportData1 = new ReportData();
  24.         reportData1.setName("demo");
  25.         reportData1.setAddress("demo address");
  26.         reportData1.setTelno("12345678");
  27.         reportDataList.add(reportData1);
  29.         // 添加更多的 ReportData 对象...
  31.         pdfReportData.setReportDataList(reportDataList);
  33.         JAXBContext jaxbContext = JAXBContext.newInstance(PdfReportData.class);
  34.         Marshaller marshaller = jaxbContext.createMarshaller();
  35.         marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
  37.         StringWriter stringWriter = new StringWriter();
  38.         marshaller.marshal(pdfReportData, stringWriter);
  40.         String xmlString = stringWriter.toString();
  41.         System.out.println(xmlString);
  42.     }
  43.     
  44.     @XmlAccessorType(XmlAccessType.FIELD)
  45.     public static class ReportData {
  47.         @XmlElement(name = "name")
  48.         private String name;
  50.         @XmlElement(name = "address")
  51.         private String address;
  53.         @XmlElement(name = "telno")
  54.         private String telno;
  56.         // Constructors, getters, and setters
  57.     }
  58. }
