XStream如何系列化反序列化Map

[kgold]

XStream xs = new XStream();
序列化成功，反序列化失败，返回空，没有Exception，具体如下：
Map storeMap = new HashMap();
String value1 = "value1";
String value2 = "value2";
storeMap.put("V1", value1);
storeMap.put("V2", value2);
FileOutputStream fs = new FileOutputStream(
"c:/temp/employeedata.txt");
xs.toXML(storeMap, fs);
//序列化OK

Map myMap= new HashMap();
FileInputStream fis = new FileInputStream(
"c:/temp/employeedata.txt");
xs.fromXML(String.valueOf(tt1), (HashMap)myMap);
//反序列化失败，返回空，没有Exception

看看这个是不是你要的!

public class Test {

	public static String getBeanToXML(SourceBean sb){
		sb.setUsername("zx");
		sb.setConnecturl("http://www.qq.com");
		sb.setDatabasename("zx_db");
		sb.setMaxactive("21");
		sb.setMaxidle("5");
		
		XStream xs=new XStream();
		xs.alias("datasource",SourceBean.class);
		return xs.toXML(sb);
	}
	
	public static SourceBean getXMLtoString(String str){
		SourceBean sb=new SourceBean();
		try {
			XStream xs=new XStream(new DomDriver());
			xs.alias("datasource",SourceBean.class);
			BufferedReader br=new BufferedReader(new FileReader(str));
			sb=(SourceBean) xs.fromXML(br);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		return sb;
	}
	public static void main(String[] args) {
		//把 SourceBean类型的对象序列化为 XML
		//SourceBean sb=new SourceBean();
		//System.out.println(getBeanToXML(sb));
		
		//逆序列化 XML 并把数据装入 Java 对象
		String str="c:/source.xml";
		SourceBean sb=getXMLtoString(str);
		System.out.println(sb.getConnecturl());
	}
}
