json解析方式

public static void main(String[] args) {
       //json格式的字符串
       String json = "{'source':'95','custelno':'','pasmid':'CBC8D8A800000001',"
               + "'userid':'','items':[{'skuo2oid':'','goodsid':22063,'skuid':34220,"
               + "'goodsname':'多力黄金三益5L/桶*4桶','goodscount':1,'channel':27}],'wholesale':'2B'}";
       //目的：取json格式的字符串的值
       //将其转化为某个具体的bean类，再取里面的属性值。
       //1.fastjson[支持单引号]
       CheckCouponInfo cci = JSON.parseObject(json, CheckCouponInfo.class);
       System.out.println(cci.getSource());
       //2.json-lib[支持单引号]
       JSONObject jsonObject = JSONObject.fromObject(json);
       CheckCouponInfo cci2 = (CheckCouponInfo) JSONObject.toBean(jsonObject, CheckCouponInfo.class);
       System.out.println(cci2.getSource());
       //3.json-mapper[不支持单引号，需要加一层配置]
       ObjectMapper mapper = new ObjectMapper();
       mapper.configure(JsonParser.Feature.ALLOW_SINGLE_QUOTES, true);//允许单引号
       CheckCouponInfo cci3 = new CheckCouponInfo();
       try {
           cci3 = mapper.readValue(json, CheckCouponInfo.class);
       } catch (JsonParseException e) {
           e.printStackTrace();
       } catch (JsonMappingException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       }
       System.out.println(cci3.getSource());
       //4.gson[支持单引号]
       Gson gson = new Gson();
       CheckCouponInfo cci4 = gson.fromJson(json, CheckCouponInfo.class);
       System.out.println(cci4.getSource());
   }

4maven:json-lib的jar包依赖

貌似还有其他的依赖，在我其他博客中有介绍。
