Spring actual combat example of using classpathresource to load XML resources

This article describes how spring uses classpathresource to load XML resources. Share with you for your reference, as follows:

One code

package lee;
import org.springframework.core.io.ClassPathResource;
import org.dom4j.*;
import org.dom4j.io.*;
import java.util.*;
import java.util.*;
public class ClassPathResourceTest
{
  public static void main(String[] args)
    throws Exception
  {
    // 创建一个Resource对象，从类加载路径里读取资源
    ClassPathResource cr = new ClassPathResource("book.xml");
    // 获取该资源的简单信息
    System.out.println(cr.getFilename());
    System.out.println(cr.getDescription());
    // 创建基于SAX的dom4j解析器
    SAXReader reader = new SAXReader();
    Document doc = reader.read(cr.getFile());
    // 获取根元素
    Element el = doc.getRootElement();
    List l = el.elements();
    // 遍历根元素的全部子元素
    for (Iterator it = l.iterator();it.hasNext() ; )
    {
      // 每个节点都是<书>节点
      Element book = (Element)it.next();
      List ll = book.elements();
      // 遍历<书>节点的全部子节点
      for (Iterator it2 = ll.iterator();it2.hasNext() ; )
      {
        Element eee = (Element)it2.next();
        System.out.println(eee.getText());
      }
    }
  }
}
