Three bean

package org.crazyit.app.service;
import org.springframework.core.io.Resource;
import org.dom4j.io.*;
import org.dom4j.*;
import java.util.*;
public class TestBean
  private Resource res;
  //Setter method of res
  public void setRes(Resource res)
    this.res = res;
  public void parse()throws Exception
    //Get simple information about the resource
    //Creating DOM 4J parser based on Sax
    SAXReader reader = new SAXReader();
    Document doc = reader.read(res.getFile());
    //Get root element
    Element el = doc.getRootElement();
    List l = el.elements();
    //Traverses all child elements of the root element
    for (Iterator it = l.iterator();it.hasNext() ; )
      //Each node is a Book node
      Element book = (Element)it.next();
      List ll = book.elements();
      //Traverse all the children of the book node
      for (Iterator it2 = ll.iterator();it2.hasNext() ; )
        Element eee = (Element)it2.next();

Four types of testing

package lee;
import org.springframework.context.*;
import org.springframework.context.support.*;
import org.springframework.core.io.*;
import org.crazyit.app.service.*;
public class SpringTest
  public static void main(String[] args) throws Exception
    ApplicationContext ctx = new
    TestBean tb = ctx.getBean("test" , TestBean.class);
