求助，JSON解析完成后怎么转成Model
大部分情况使用json的格式来传递参数，但是使用起来就不太方便了，因此需要将json转换成对应的model，然后对model进行操作就很便利了。json转model的方法也有很多，推荐一个就是，jackson，方法是这样的。
public static
ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
T t = mapper.convertValue(fromValue, toValueType);
return t;
}
json数据中有json数组 怎么解析
实例：
import net.sf.json.JSONArray;
public class TestJson
{
public static void main(String []args)
{
String json = "[{\"a\":\"111\",\"b\":\"222\",\"c\":\"333\"},{\"a\":\"1000\",\"b\":\"2000\",\"c\":\"000\"},{\"a\":\"999\",\"b\":\"300\",\"c\":\"700\"}]";
JSONArray jsonArr = JSONArray.fromObject(json);
String a[] = new String[jsonArr.size()];
String b[] = new String[jsonArr.size()];
String c[] = new String[jsonArr.size()];
for (int i = 0; i < jsonArr.size(); i++) {
a[i] = jsonArr.getJSONObject(i).getString("a");
b[i] = jsonArr.getJSONObject(i).getString("b");
c[i] = jsonArr.getJSONObject(i).getString("c");
}
for (int i = 0; i < c.length; i++) {
System.out.print(a[i]+" ");
System.out.print(b[i]+" ");
System.out.print(c[i]);
System.out.println();
}
}
}
