xml：

<?xml version="1.0" encoding="UTF-8"?>
<CONFIG>
    <VALUE>
        <!-- 正负样本比参数名称 -->
        <sampleMonitorField>is_click</sampleMonitorField>
        <!-- 正负样本比参数索引位置 -->
        <arrPosition>6</arrPosition>
    </VALUE>
</CONFIG>

demo class：

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import java.io.File;
import java.util.Iterator;
public class demo { 
    public static void main(String[] args) { 
        try { 
            File f = new File("src/main/resource/test.xml");
            if (!f.exists()) { 
                System.out.println(" Error : Config file doesn't exist!");
                System.exit(1);
            }
            SAXReader reader = new SAXReader();
            Document doc;
            doc = reader.read(f);
            Element root = doc.getRootElement();
            Element data;
            Iterator<?> itr = root.elementIterator("VALUE");
            data = (Element) itr.next();
            String sampleMonitorField = data.elementText("sampleMonitorField").trim();
            Integer arrPos = Integer.parseInt(data.elementText("arrPosition").trim());
            System.out.println(sampleMonitorField);
            System.out.println(arrPos);
        } catch (Exception ex) { 
            System.out.println("Error : " + ex.toString());
        }
    }
}
