昨天写的一个使用jdom读写xml文件的一个例子:
/** 生成返回结果XMl*/ public boolean writeXML(String guid, String path) { boolean temp = false; List<SynchronousJournal> listSuccess = synchronousJournalManager .quereySynchronousJournal(guid); List<SynchronousJournal> listError = synchronousJournalManager .quereySynchronousJournalErroe(guid); File file = new File(path);// 创建一个xml文件 try { Element root = new Element("RESULTLIST");// 创建根元素 for (SynchronousJournal synchronousJournal : listSuccess) { Element result = new Element("RESULT");// 创建子元素 root.addContent(result);// 添加子元素到根节点 Element type = new Element("TYPE");// 创建叶子节点 result.addContent(type);// 添加叶子节点到父节点 Element businessType = new Element("BUSINESSTYPE");// 创建叶子节点 businessType.addContent(businessType);// 添加叶子节点到父节点 type.setText(synchronousJournal.getBusinesstype());// 给叶子节点赋值 /** 成功信息 */ Element success = new Element("SUCCESS");// 创建叶子节点 success.setText(synchronousJournal.getCount().toString());// 给叶子节点赋值 type.addContent(success);// 添加叶子节点到父节点 int a = 0; for (SynchronousJournal synchronousJournal2 : listError) { if (synchronousJournal.getBusinesstype().equals( synchronousJournal2.getBusinesstype())) a++; } Element error = new Element("ERROR"); type.addContent(error); Element errorcount = new Element("ERRORCOUNT"); error.setText(String.valueOf(a));// 给叶子节点赋值 error.addContent(errorcount); for (SynchronousJournal synchronousJournal2 : listError) { /** 失败信息 */ if (synchronousJournal.getBusinesstype().equals( synchronousJournal2.getBusinesstype())) { Element errorguid = new Element("ERRORGUID"); error.setText(synchronousJournal2.getInfoGuid());// 给叶子节点赋值 error.addContent(errorguid); } } } Document doc = new Document();// 创建文本对象 doc.addContent(root);// 添加树倒文本中 Format format = Format.getCompactFormat(); format.setIndent(" "); XMLOutputter out = new XMLOutputter(format);// 创建输出流 FileWriter fw = new FileWriter(file);// 写数据 out.output(doc, fw);// 输出到xml文件中 fw.close();// 关闭写入流 temp = true; } catch (Exception e) { e.printStackTrace(); } finally { } return temp; } /** 读取返回结果xml*/ public static boolean readXml(String path) { boolean temp = false; SAXBuilder sb = new SAXBuilder();// 构建一个JDOM文档输入流 try { Document doc = sb.build(path);// 加载xml Element root = doc.getRootElement();// 获得xml文件的内容 List list = root.getChildren();// 把xml文件内容转化成数组形式 for (int i = 0; i < list.size(); i++) { Element result = (Element) list.get(i);// 获得数组中的一个对象 List typelist = result.getChildren("TYPE"); for (int j = 0; j < typelist.size(); j++) { Element type = (Element) typelist.get(j);// 获得xml文件的内容 System.out.println(type.getChildText("BUSINESSTYPE")); String success=type.getChildText("SUCCESS"); System.out.println("成功 "+success+"条数据"); Element error = type.getChild("ERROR");// 获得xml文件的内容 String errorCount = error.getChildText("ERRORCOUNT");// 获得对象的其中一个元素 System.out.println("失败 "+errorCount+"条数据"); List errorguid = error.getChildren("ERRORGUID");// 把xml文件内容转化成数组形式 String empno1 = "失败数据guid:"; for (int a = 0; a < errorguid.size(); a++) { Element emp1 = (Element) errorguid.get(a);// 获得数组中的一个对象 empno1 = empno1 + " " + emp1.getText(); } System.out.println(empno1); } // } } temp = true; } catch (JDOMException e) { // TODO Auto-generated catch block e.printStackTrace(); temp = false; } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); temp = false; } return temp; }<?xml version="1.0" encoding="UTF-8"?>
