import java.io.IOException;import java.net.URL;import org.apache.commons.digester.Digester;import org.apache.commons.digester.xmlrules.DigesterLoader;import org.xml.sax.SAXException;public class XmlParser{    private Object object;    public Object parseXml2Bean(String xmlPath)    {        return this.parseXml2Bean(xmlPath, null);    }    // 将配置文件映射为javaBean    public Object parseXml2Bean(String xmlPath, String rulePath)    {        String ruleXmlPath = "";        if (rulePath == null)        {            ruleXmlPath = "conf/rulefile/xmlrules.xml";// default数据装载逻辑配置文件        }        else        {            ruleXmlPath = rulePath;        }        String datafileName = "";        URL rulesURL = null;        String basePath = XmlParser.class.getResource("/").getPath();        datafileName = basePath + xmlPath;        rulesURL = XmlParser.class.getClassLoader().getResource(basePath + ruleXmlPath);        Digester d = DigesterLoader.createDigester(rulesURL); // url形式        d.setClassLoader(XmlParser.class.getClassLoader());        try        {            object = d.parse(XmlParser.class.getClassLoader().getResourceAsStream(datafileName)); // InputStream input        }        catch (IOException e)        {            throw new ParseException(104, e);        }        catch (SAXException e)        {            throw new ParseException(105, e);        }        return object;    }}

依赖apache的四个包：

commons-digester-2.1.jar

commons-logging-1.1.1.jar

commons-beanutils-1.8.3.jar

commons-collections-3.2.1.jar

用到类Digester、DigesterLoader等，引入commons-digester-2.1.jar

用到类Log、LogFactory等，引入commons-logging-1.1.1.jar

用到类DynaProperty等，引入commons-beanutils-1.8.3.jar

至于commons-collections-3.2.1.jar，在以下所示实例中，不引入也可以，还没有涉及到这个包，在以后的应用的，根据具体情况确定是否引入。
