為以上 XML 文件構造 Propertys 類:
public class Propertys {public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getFIEld() {
return fIEld;
}
public void setField(String fIEld) {
this.field = fIEld;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
讀取方法(返回包含 Propertys 的列表):
public List getAll() {
List list = new ArrayList();
try {
InputStream is = getClass().getResourceAsStream("/navigation.XML");
SAXReader reader = new SAXReader();
Document document = reader.read(is);
Element root = document.getRootElement();
Iterator lv = root.elementIterator("propertset");
Element el = null;
while (lv.hasNext()) {
Propertys property=new Propertys();
el = (Element) lv.next();
property.setName(el.attributeValue("name"));
property.setDescription(el.attributeValue("description"));
property.setField(el.elementText("fIEld"));
list.add(property);
}
} catch (Exception e) {
e.printStackTrace();
}
return list;
}
添加新節點(成功返回 1 否則 0):
public int saveProperty(Propertys property) {
try {
InputStream is = getClass().getResourceAsStream("/navigation.XML");
SAXReader reader = new SAXReader();
Document document = reader.read(is);
Element root = document.getRootElement();
root.addElement("propertset")
.addAttribute("name",property.getName())
.addAttribute("description",property.getDescription())
.addElement("field").addText(property.getFIEld());
OutputFormat outformat = OutputFormat.createPrettyPrint();
outformat.setEncoding("GBK");
FileWriter out = new FileWriter(
System.getProperty("user.dir")
+"/web/WEB-INF/classes/navigation.XML");
XMLWriter writer=new XMLWriter(out,outformat);
writer.write(document);
writer.close();
return 1;
} catch (Exception e) {
e.printStackTrace();
}
return 0;
}
public int updateProperty(String pro,Propertys property) {
try {
InputStream is = getClass().getResourceAsStream("/navigation.XML");
SAXReader reader = new SAXReader();
Document document = reader.read(is);
Element root = document.getRootElement();
Iterator lv = root.elementIterator("propertset");
Element el = null;
while (lv.hasNext()) {
el = (Element) lv.next();
if (el.attributeValue("name").equals(pro)) {
el.setAttributeValue("name",property.getName());
el.setAttributeValue("description",property.getDescription());
el.element("field").setText(property.getFIEld());
}
}
OutputFormat outformat = OutputFormat.createPrettyPrint();
outformat.setEncoding("GBK");
FileWriter out = new FileWriter(
System.getProperty("user.dir")
+"/web/WEB-INF/classes/navigation.XML");
XMLWriter writer=new XMLWriter(out,outformat);
writer.write(document);
writer.close();
return 1;
} catch (Exception e) {
e.printStackTrace();
}
return 0;
}
刪除節點:
public int delProperty(String pro) {
try {
InputStream is = getClass().getResourceAsStream("/navigation.XML");
SAXReader reader = new SAXReader();
Document document = reader.read(is);
Element root = document.getRootElement();
Iterator lv = root.elementIterator("propertset");
Element el = null;
while (lv.hasNext()) {
el = (Element) lv.next();
if (el.attributeValue("name").equals(pro)) {
el.detach();
}
}
OutputFormat outformat = OutputFormat.createPrettyPrint();
outformat.setEncoding("GBK");
FileWriter out = new FileWriter(
System.getProperty("user.dir")
+"/web/WEB-INF/classes/navigation.XML");
XMLWriter writer=new XMLWriter(out,outformat);
writer.write(document);
writer.close();
return 1;
} catch (Exception e) {
e.printStackTrace();
}
return 0;
}
