Json数据转换list对象实现思路及代码

json代码：

[{"cid":2,"cname":"\u767d\u841d\u535c","amount":26,"price":"17"},{"cid":3,"cname":"\u80e1\u841d\u535c","amount":21,"price":"21"},{"cid":4,"cname":"\u7389\u7c73","amount":7,"price":"23"},{"cid":14,"cname":"\u897f\u74dc","amount":7,"price":"29"},{"cid":5,"cname":"\u571f\u8c46","amount":3,"price":"24"},{"cid":1,"cname":"\u8349\u8393","amount":427,"price":"27"},{"cid":10,"cname":"\u5357\u74dc","amount":303,"price":"30"},{"cid":11,"cname":"\u82f9\u679c","amount":1,"price":"24"},{"cid":23,"cname":"\u77f3\u69b4","amount":4,"price":"54"},{"cid":18,"cname":"\u6843\u5b50","amount":3,"price":"40"},{"cid":15,"cname":"\u9999\u8549","amount":9,"price":"32"},{"cid":13,"cname":"\u8461\u8404","amount":7,"price":"47"},{"cid":26,"cname":"\u67da\u5b50","amount":1,"price":"58"},{"cid":27,"cname":"\u83e0\u841d","amount":5,"price":"62"},{"cid":19,"cname":"\u6a59\u5b50","amount":27,"price":"41"}]
