项目笔记：导入功能

　　前台JS：注意：url后的  ?disc=baseLineTemplate  是必须要加的，因为要走先处理一下

var serialNumberUrl = "";
 $(function() {
 $("#buttonSubmit").bind("click", function() {
var serialNumberFileVal = $("#serialNumberFile").val();
 serialNumberFileVal = serialNumberFileVal.substring(serialNumberFileVal.lastIndexOf('.') + 1);
if (serialNumberFileVal != "xml") {
 showAlertDialog("提示", "请选择xml文件上传");
return false;
 } else {
 serialNumberUrl = "${basePath}/genuineSerialNumberManagementAction_importSerialNumber.do?disc=baseLineTemplate";
 document.serialNumber_importSerialNumber.action = serialNumberUrl;
 serialNumber_importSerialNumber.submit();
 }
 });
/** 验证文件是否导入成功 */ 
 $("#serialNumber_importSerialNumber").ajaxForm(function(data){
 setMessage(data);
 });
 });

　　后台解析数据：

//导入模板
public void importSerialNumber(){
this.msg = RESULT_ERROR;
try{
// 记录文件上传的MAP对象
        User currentUser = SessionUtil.getInstance().getUserFromSession(this.getRequest());
 final String name = currentUser.getAccount().trim();// 加入实际项目后，获取文件上传的系统用户名称，即登录用记名称，唯一性
for (Entry<String, String[]> entry : FileUploadConstant.fileOperator_baseTemplate.entrySet()) {
 File file = new File(entry.getValue()[1]);
this.msg = genuineSerialNumberManagementService.importTemplate(file);
 FileUploadConstant.fileOperator_baseTemplate.remove(entry.getKey());
 }
 FileUploadConstant.fileOperator_baseTemplate.clear();
 genuineSerialNumberManagementService.createXML();
 }catch(Exception e){
 log.error("导入规则库失败!", e);
this.msg = RESULT_ERROR;
 }
 print(this.msg);
}

public String importTemplate(File file) {
 String message = "error";
try {
//获取文件
        Document doc = XMLUtil.getDocument(file.getPath());
// 获取根节点
        Element root = doc.getRootElement();
//根据根节点判断type值
        Integer type = null;
if("SoftLicW".equals(root.getQName().getName())){
 type = 1;
 }else if("SoftLicB".equals(root.getQName().getName())){
 type = 0;
 }
// 获取Software节点
        Iterator<?> ruleNode = root.elementIterator("Software");
// 循环Software节点,判断是否存在
while (ruleNode.hasNext()) {
 Element ruleElement = (Element) ruleNode.next();
 Attribute ruleXmlId = ruleElement.attribute("SoftId");
 Attribute ruleXmlName = ruleElement.attribute("DisplayName");
// 获取license节点
            Iterator<?> license = ruleElement.elementIterator("license");
// 循环license节点,判断是否存在
while (license.hasNext()) {
 Element licenseElement = (Element) license.next();
 Attribute licenseVersion = licenseElement.attribute("Version");
 Attribute licenseValue = licenseElement.attribute("value");
 GenuineSerialNumberManagement serialNumber = new GenuineSerialNumberManagement();
 serialNumber.setType(type);
 serialNumber.setSoftId(Integer.valueOf(ruleXmlId.getText()));
 serialNumber.setSoftDisplayName(ruleXmlName.getText());
 serialNumber.setVersion(licenseVersion.getText());
 serialNumber.setSerialNumber(licenseValue.getText());
 genuineSerialNumberManagementDao.save(serialNumber);//保存解析出来的数据到数据库
 }
 }
 message = "success";
 } catch (Exception e) {
 e.printStackTrace();
 message = "error";
 }
return message;
