读取xml文件数据导入数据库

粘贴出来仅供大家参考，重点要放在读取xml上。

//找到需要读取的XML文件的位置
Document doc = null;
//主键自增
int i = 1;
try {
    System.out.println(request.getRequestURL()+"+"+request.getRealPath("/"));
    in = new FileInputStream(new File("G:/import.xml"));
    doc = new SAXReader().read(in);

    Map mapNumber = sqlRunner.queryForMap(sqlRunner.sql("import.base.search_base_station"));
    if(mapNumber.get("NUM")!=null){
        i=Integer.parseInt(mapNumber.get("NUM").toString())+1;
    }
} catch (DocumentException e1) {
    e1.printStackTrace();
} catch (FileNotFoundException e1) {
    e1.printStackTrace();
} catch (SQLException e1) {
    e1.printStackTrace();
}

Element root = doc.getRootElement();//获取根元素
List<Element> childElements = root.elements();//获取当前元素下的全部子元素
List<Map> mapList = new ArrayList<Map>();
for (Iterator iter = childElements.iterator();iter.hasNext();) {
    i++;
    Element el = (Element) iter.next();
    List turnosList=el.elements("xmlColum");
    Map<String,Object> map = new HashMap<String,Object>();
    map.put("INSTANCE_ID",i);
    for(Iterator iter1=turnosList.iterator();iter1.hasNext();) {
        Element el2 = (Element) iter1.next();
        String index = el2.elementText("xmlIndex");
        String name = el2.elementText("xmlName");
        String value = el2.elementText("xmlValue");
        map.put(name,value);
    }
    mapList.add(map);
}

读取时要注意xml的节点结构
