dom4j xml 生成
该项目采用dom4j从数据库表中生成xml数据
项目文档、数据库建表语句均已放置在项目中。
关键代码如下：
public String getXml(Connection conn, int rm_id, String path) {
//声明xml字符串
String fileString = "";
//创建DAO对象
MachineroomDao machineroom_dao = new MachineroomDao();
Cab_equipmentDao cab_equipment_dao = new Cab_equipmentDao();
Equip_configDao equip_config_dao = new Equip_configDao();
EquipmentDao equipment_dao = new EquipmentDao();
//添加room，第一层
Machineroom machineroom_dto = machineroom_dao.findById(conn, rm_id);//设置房间号
//获取个属性的值.如果为null,将属性设为""
String getMr_id = new Integer(machineroom_dto.getMr_id()).toString();
String getMr_name = machineroom_dto.getMr_name();
if(getMr_id == null) getMr_id = "";
if(getMr_name == null) getMr_name = "";
Document document = DocumentHelper.createDocument();
Element rooms_racks = document.addElement("rooms-racks");
Element room = rooms_racks.addElement("room");
room.addAttribute("id", getMr_id);
room.addAttribute("name", getMr_name);
room.addAttribute("isSelected", "true");
//添加rack，第二层
List cab_equipment_list = cab_equipment_dao.findById(conn, path, machineroom_dto.getMr_id());
for (int i = 0; i < cab_equipment_list.size(); i++) {
Cab_equipment cab_equipment_dto = cab_equipment_list.get(i);
//获取个属性的值.如果为null,将属性设为""
String getE_id = cab_equipment_dto.getE_id();
String getEqucab_name = cab_equipment_dto.getEqucab_name();
String getX = cab_equipment_dto.getX() + "";

//将float后的".0"去掉
if(cab_equipment_dto.getX()%1 == 0) getX = (int)cab_equipment_dto.getX()+"";
if(cab_equipment_dto.getY()%1 == 0) getY = (int)cab_equipment_dto.getY()+"";

//添加device，第三层
