我正在开发一个使用 Spring MVC 和 Hibernate 的 Web 应用程序，
我的字段类型是 Clob，值是 XML， 之前使用 SAXParser 解析了 clob， 如何使用 SAXParser 中的元素并将其显示到表中，
我真的不知道如何将 SAXParser 中的元素显示到我的表 (JSP)
这是我的代码，
@RequestMapping(value="/admin/Detail-BPJS-TK.html")
public ModelAndView listDetailBPJSTK(ModelMap model, HttpServletRequest request, HttpServletResponse response)throws ParserConfigurationException, SAXException, Exception{
if(!((request.getParameter("MESSAGEID")) == null)){
String MESSAGEID = request.getParameter("MESSAGEID");
System.out.println(MESSAGEID);
//140721438362
//DetailBPJS detailbpjs = detailbpjsService.get(MESSAGEID);
//String tes = detailbpjs.getMESSAGEID();
//System.out.println(tes);
Configuration cfg = new Configuration();
cfg.configure("hibernatesoaappbpjstk.cfg.xml");
SessionFactory factory = cfg.buildSessionFactory();
Session session = factory.openSession();
String pay = "PAYMENT";
String sub = "PROCESSED";
Query query = session.createQuery("from DetailBPJS where TRANSACTION = :tra and SUBTRANSACTION = :sub and MESSAGEID = :mes");
query.setParameter("tra", pay);
query.setParameter("sub", sub);
query.setParameter("mes", MESSAGEID);
@SuppressWarnings("unchecked")
List <DetailBPJS> result = query.list();
if(result.isEmpty()){
System.out.println("Please, check the 'No. Billing' again!!");
System.out.println(MESSAGEID);
model.addAttribute("errorMessageBPJSTK", "true");
}else{
DetailBPJS data = (DetailBPJS)result.get(0);
String nom1 = data.getTRANSACTION();
String nom2 = data.getSUBTRANSACTION();
String nom3 = data.getUUID();
Clob nom4 = data.getRAWDATA();
System.out.println(nom1 + " - " + nom2 + " - " + nom3 + " - " + nom4);
//140721438362
//convert clob to java.io.reader
Reader myclob = nom4.getCharacterStream();
System.out.println(myclob);
//create InputSource from Reader
InputSource myinput = new InputSource(myclob);
System.out.println(myinput);
try {
SAXParserFactory factoryz = SAXParserFactory.newInstance();
SAXParser saxParser = factoryz.newSAXParser();
System.out.println(saxParser);
DefaultHandler handler = new DefaultHandler(){

任何帮助都会很高兴:) ~
最佳答案
您可以直接将String值添加到ModelMap并从jsp访问它们，与“errorMessageBPJSTK”相同。
if(b_num){
model.addAttribute("billingNumber",new String(ch, start, length));
b_num = false;
}
if(b_krb){
model.addAttribute("kodeRefBank",new String(ch, start, length));
b_krb = false;
}
并在jsp中访问它们，例如；
<td>Billing Number : </td>
<td>${billingNumber}</td>
