在Java中使用Jdom读取xml配置文件

现有一Web项目，在src目录下有配置文件WebConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<services>
	<service name="apnServer" url="http://192.168.1.89:7070/"/>
</services>

手写XML解析类，前提需要在项目中添加jdom-2.0.5.jar、jaxen-1.1.1.jar  两个jar包

import java.io.IOException;
import java.util.List;

import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;
import org.jdom2.xpath.XPath;

public class XMLParse {
	//从文档中解析对应的url
	public static String getContent(String attributeName){
		SAXBuilder sax = new SAXBuilder(); 
		 Document doc;
		try {
			doc = sax.build(XMLParse.class.getResource("/").getPath()+"WebConfig.xml");
			Element rootEle = doc.getRootElement();  
	         
	        List serviceList = XPath.selectNodes(rootEle, "//services/service"); 
	        if(serviceList!=null&&serviceList.size()>0){
	        	for (int i = 0; i < serviceList.size(); i++) {
					Element service=(Element)serviceList.get(i);
					if(attributeName!=null&&attributeName.equals(service.getAttributeValue("name"))){
						return service.getAttributeValue("url");
					}
				}
	        }else{
	        	return null;
	        }
	        
		} catch (JDOMException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}  
		return null;
	}
}

在其他类中可以进行调用

public class GetPostUtil {
	public  static String androidPushNotificationURL = "";
	static{
		androidPushNotificationURL=XMLParse.getContent("apnServer");
	}
}
