 Excel转成JSON

package Action.Excel2;

import jxl.Sheet;
import jxl.Workbook;
import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

import java.io.File;

public class Excel2JSON {

    /**
     * 将Excel数据转为JSON格式数组(题对象list)
     *@param name Excel路径
     *@return Json格式数组
     */
    public static String excel2Json(String name) {
        Sheet sheet;
        Workbook book;
        Cell cell1, cell2, cell3, cell4, cell5,cell6,cell7,cell8;
        JSONArray array = new JSONArray();
        try {
            //为要读取的excel文件名  "F://a.xls"
            book = Workbook.getWorkbook(new File("F://a.xls"));

            //获得第一个工作表对象(ecxel中sheet的编号从0开始,0,1,2,3,....)

 JSON转成List

package Action.Excel2;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.junit.Test;

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import com.sun.org.apache.bcel.internal.generic.Type;

import bean.Question;

public class JSON2BeanList {
    
    
    
//    测试JSON转list
    /**
     * 将字符串转为list集合对象
     *@param json json数组字符串
     *@return list集合
     */
    @SuppressWarnings("unchecked")
    public static  List<Question> json2list(String json){
        List<Question> list = new ArrayList<Question>();
        Gson gson = new Gson();
        list = (List<Question>) gson.fromJson(json, new TypeToken<List<Question>>(){}.getType());
        return list;
    }
    
}
