String 转对象的几个中方式，之前没空。现在列出来mark一下

String ingredientsLista = request.getParameter("list");

       // 这是jar包 fastjson-1.1.24.jar
       //方式1 直接将数据转成单个对象 方便存储
		JSONArray array = JSONArray.parseArray(ingredientsLista);
		for(int i = 0 ; i
 
   jsonmap = (Map
  
   ) array.get(i); ri.setIngredientsId(jsonmap.get("ingredientsid")); ri.setIngredientsName(jsonmap.get("ingredientsname")); ri.setRecipeId(recipeid); ingredientDAO.saveIngredients(ri); } //这是jar包 json-lib-2.4-jdk15.jar //方法2 将数据转换成list net.sf.json.JSONArray data = net.sf.json.JSONArray.fromObject(ingredientsLista); List
   
     plist1 = data.toList(data, RecipeForSearchInfo.class); for(int i =0;i
    
      plist2= FJsonUtil.toList(ingredientsLista,RecipeForSearchInfo.class); for(int i =0;i
