需要从中获得pagecount的文本以及list中每个股票的NAME和CODE。

Solution：使用jackson完成此任务。

Steps：

1.引入jackson依赖

        <!-- jackson -->

        <dependency>

          <groupId>com.fasterxml.jackson.core</groupId>

          <artifactId>jackson-databind</artifactId>

        </dependency>

        <dependency>

          <groupId>com.fasterxml.jackson.core</groupId>

          <artifactId>jackson-annotations</artifactId>

        </dependency>

        <dependency>

          <groupId>com.fasterxml.jackson.core</groupId>

          <artifactId>jackson-core</artifactId>

        </dependency>

2.解析

            ObjectMapper mapper = new ObjectMapper();

            JsonNode node = mapper.readTree(json);// json就是上面的大段待解析文本

            pageCount = Integer.parseInt(node.get("pagecount").asText());// 取pagecount

            JsonNode listNode=node.path("list");

            Iterator<JsonNode> iterator = listNode.elements(); // 准备遍历list节点

            while (iterator.hasNext()) {

                JsonNode stock = iterator.next();

                String code=stock.get("CODE").asText(); // 取code

                String name=stock.get("NAME").asText(); // 取name

                Stock s=new Stock(idx++,code,name);

                stockList.add(s);

                //System.out.print(code + " "+name);

             }
