利用gson实现object转map,谁用谁舒服~

package com.royalnu.common.utils.json;

import java.util.Collections;;
import java.util.HashMap;
import java.util.Map;
import com.google.gson.Gson;

public class GsonUtil {
	
	private GsonUtil(){

	}

	public static final Gson GSON = new Gson ();
	
	public static Map<String, Object> Object2Map(Object obj){
		if(obj == null){
			return Collections.emptyMap();
		}
		
		return GSON.fromJson(GSON.toJson(obj), Map.class);
	}
	
	public static Map<String, String> Object2MapString(Object obj){

			return Collections.emptyMap();
		}
		return GSON.fromJson(GSON.toJson(obj), Map.class);
	}
	
}
