本例中我用的是Gson解析json，解析代码如下：

/** * Created by lishuangxiang on 2015/12/18. */public class ParseJson {    public static <T> T convertJson(String json,Class<T> clazz){        Gson gson = new Gson();        T t = gson.fromJson(json,clazz);        return t;    }}

测试代码：

String json="";//json格式字符串CourseForumGson courseForumGson=ParseJson.convertJson(json, CourseForumGson.class);

可见使用GsonFormat插件生成实体，对于复杂的json数据而言省时省力。
