Java反射xml数据到类中

我们做自动化测试时，会遇到使用xml存储数据，但是这些数据可以封装成一个类，进行数据的传递。以下通过一个实际的例子，展示给大家，请欣赏。

第一步：xml存储将要使用的数据

第二步：读取xml文件的方法

package com.test;

import java.io.File;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class ParserXml {

    @SuppressWarnings({ "rawtypes", "unchecked" })
	public List parser3Xml(String fileName) {
        File inputXml = new File(fileName);    
        List list=new ArrayList();                
        SAXReader saxReader = new SAXReader();
        try {
            Document document = saxReader.read(inputXml);
            Element employees = document.getRootElement();
            for (Iterator i = employees.elementIterator(); i.hasNext();) {
                Element employee = (Element) i.next();
                Map map = new HashMap();
                Map tempMap = new HashMap();
                for (Iterator j = employee.elementIterator(); j.hasNext();) {
                    Element node = (Element) j.next();                    
                    tempMap.put(node.getName(), node.getText());                    
                }
                map.put(employee.getName(), tempMap);
                list.add(map);
            }
        } catch (DocumentException e) {
            System.out.println(e.getMessage());
        }
        return list;
    }    
}

第三步：xml数据文件的类

package com.test;

public class testMethod1 {

	private String input;
	private String button;
	
	public void setInput(String input) {
		this.input = input;
	}
	public String getInput() {
		return input;
	}
	public void setButton(String button) {
		this.button = button;
	}
	public String getButton() {
		return button;
	}
}

第四步：处理方法

package com.test;

import java.io.File;
import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;


public class TestData {        
    
    @SuppressWarnings("rawtypes")
	private static List l;
    
    public TestData() {    
        this.getXmlData();        
    }
    
    public void getXmlData(){
        ParserXml p = new ParserXml();
        l = p.parser3Xml(new File("src/TestData.xml").getAbsolutePath());
    }

	@SuppressWarnings({ "rawtypes", "unchecked" })
    public static List providerMethod(){        
        List oList = new ArrayList();; 
        l = (new ParserXml()).parser3Xml(new File("src/TestData.xml").getAbsolutePath());
        for (int i = 0; i < l.size(); i++) {
            Map m = (Map) l.get(i);  
            String key = (String)m.keySet().iterator().next();
            Class demo = null;
            Object obj = null;
            try{
            	demo = Class.forName("com.test." + key);
            }catch(Exception e){
            	e.printStackTrace();
            }
            try{
            	obj = demo.newInstance();
            }catch(Exception e){
            	e.printStackTrace();
            }
            Map dm = (Map) m.get(key);
            
            for(Entry entry: dm.entrySet()){
            	String key1 = entry.getKey();
            	String value = entry.getValue();
            	setter(obj,key1,value,String.class);
            }
            oList.add(obj);
        }  
        return oList;
    }
    
    
    /**
     * @param obj
     *            操作的对象
     * @param att
     *            操作的属性
     * @param value
     *            设置的值
     * @param type
     *            参数的属性
     * */
    public static void setter(Object obj, String att, Object value,
            Class type) {
        try {
            Method method = obj.getClass().getMethod("set" + att, type);
            method.invoke(obj, value);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    @SuppressWarnings("rawtypes")
	public static void main(String[] args) {
    	List list = TestData.providerMethod();
    	for(int i=0;i
