java后台处理前端传的json串方法

 var json='{"goodName":"果粒橙","good ":"这是一种好喝的","goodMessage":"这个很好喝，你还想喝 吗。。。。。。。。","goodCost":"2","goodPrice":"2.5","goodPicture":"image/","goodSellcount":"20","goodDtock":"200"}';
$.post("add_good",{"name":json},function(){
alert("添加成功");
}); 

//得到json对象

JSON  json  = JSON .from (name);

Goods g = new Goods();

//将json对象转换为json字符串
g.setGoodName( json .getString("goodName"));

g.setGood ( json .getString("good "));

g.setGoodMessage( json .getString("goodMessage"));

g.setGoodCost( json .getString("goodCost"));

g.setGoodPrice( json .getString("goodPrice"));

g.setGoodPicture( json .getString("goodPicture"));

g.setGoodSellcount( json .getString("goodSellcount"));

g.setGoodDtock( json .getString("goodDtock"));

//调用Dao层借口 添加进数据库

Goods.save(g);

json  = JSON .from (name);
g = (Goods) json .toBean(json ,Goods.class);
Goods.save(g)
