//这是一个xml文件，是我项目中的一个文件，我对它进行了分析

<beans.....>

<bean id="" class=""> //id就是一个标识，可以被当做另一个节点里的ref，class是一个类，下面的在本类中执行

实现呢

//* 将XML文件输出到指定的路径
public static void outputXml(Document doc,String fileName)
throws Exception {
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
DOMSource source = new DOMSource(doc);
transformer.setOutputProperty(OutputKeys.ENCODING,"UTF-8");
transformer.setOutputProperty(OutputKeys.INDENT,"yes");// 设置文档的换行与缩进
PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
StreamResult result = new StreamResult(pw);
transformer.transform(source,result);
System.out.println("生成XML文件成功!");
}

//////创建生成xml

public static void createXml(String fileName) {
Element root = document.createElement("listProtocolDataItemConfig");
document.appendChild(root); //填充 根

int i =0;//0000FF00
do{
StringBuilder thr = null;
String codede = "";

thr = new StringBuilder();
thr.append("0000");
String hex = Integer.toHexString(i);
if (hex.length() < 2) {
hex = "0" + hex;
}
if(i == 64)
hex = "FF";
thr.append(hex).append("00");
codede = thr.toString().toUpperCase();//数据表示

String namee =String.format("(当前)组合有功费率 "+Integer.toString(i)+"电能");

Element employee = document.createElement("ProtocolDataItemConfig"); //节点

Element DI = document.createElement("code"); //成员1
DI.appendChild(document.createTextNode(codede));
employee.appendChild(DI); //填充节点的成员1

Element Cformat = document.createElement("code_format"); //成员2
if(i == 64)
Cformat.appendChild(document.createTextNode("**"));
else
Cformat.appendChild(document.createTextNode("SG11"));
employee.appendChild(Cformat); //填充节点的成员2

Element name = document.createElement("REMARK");
if(i == 0)
name.appendChild(document.createTextNode("(当前)组合有功总电能")); //成员3
else if(i == 64)
name.appendChild(document.createTextNode("(当前)组合有功电能数据块")); //成员3
else
name.appendChild(document.createTextNode(namee)); //成员3
employee.appendChild(name); //填充节点的成员3

root.appendChild(employee);//填充 节点
i++;
}while(i<65);

TransformerFactory tf = TransformerFactory.newInstance();
try {
Transformer transformer = tf.newTransformer();
DOMSource source = new DOMSource(document);
transformer.setOutputProperty(OutputKeys.ENCODING,"UTF-8");
transformer.setOutputProperty(OutputKeys.INDENT,"yes");
PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
StreamResult result = new StreamResult(pw);
transformer.transform(source,result);
System.out.println("生成XML文件成功!");
} catch (TransformerConfigurationException e) {
System.out.println(e.getMessage());
} catch (IllegalArgumentException e) {
System.out.println(e.getMessage());
} catch (FileNotFoundException e) {
System.out.println(e.getMessage());
} catch (TransformerException e) {
System.out.println(e.getMessage());
}
}

public static void main(String args[]){
A0xml dd=new A0xml();
String str="./SG645.xml";
dd.init();
A0xml.createXml(str); //创建xml
}

这就是我的实现了，具体实现可以自行查看Spring的注入方法

下面的我转的，觉得很好
