1： API json多层数据实体类封装（利用泛型技术）

RootEntity.java
[code]public class RootEntity<T>{ private int showapi_res_code; private String showapi_res_error; private PageBeanBody<T> showapi_res_body; //省略get set方法 }

PageBeanBody.java
[code]public class PageBeanBody<T> { private PageBean<T> pagebean; private int ret_code; //省略get set方法 }

PageBean.java
[code]public class PageBean<T> { private int allNum; private int allPages; private int currentPage; private int maxResult; private List<T> contentlist; //省略get set方法 }

泛型方法
[code] public static <T> RootEntity<T> parseNewsList(Response response,Class<T> mClazz) { JSONObject root=JSON.parseObject(response.getResponseText()); JSONObject body=JSON.parseObject(response.getResponseText()).getJSONObject("showapi_res_body"); JSONObject page=JSON.parseObject(response.getResponseText()).getJSONObject("showapi_res_body").getJSONObject("pagebean"); String contentList=JSON.parseObject(response.getResponseText()).getJSONObject("showapi_res_body").getJSONObject("pagebean").getJSONArray("contentlist").toJSONString(); //实例化分页类 PageBean<T> pageBean=new PageBean<T>(); pageBean.setContentlist(JSON.parseArray(contentList, mClazz));//可能报错 pageBean.setAllNum(page.getIntValue("allNum")); pageBean.setAllPages(page.getIntValue("allPages")); pageBean.setCurrentPage(page.getIntValue("currentPage")); pageBean.setMaxResult(page.getIntValue("maxResult")); //实例化Body类 PageBeanBody<T> pageBeanBody=new PageBeanBody<T>(); pageBeanBody.setPagebean(pageBean); pageBeanBody.setRet_code(body.getIntValue("ret_code")); //实例化Root类 RootEntity<T> rootEntity=new RootEntity<T>(); rootEntity.setShowapi_res_body(pageBeanBody); rootEntity.setShowapi_res_code(root.getIntValue("showapi_res_code")); rootEntity.setShowapi_res_error(root.getString("showapi_res_error")); return rootEntity; }

调用泛型方法
[code]public static void loadNewsList(String url, Map<String, Object> param, LinkedHashMap<String, Object> headers, String bodyJson, String post) { Response response = StaticUtil.commomHttpMethod(url, param, headers, bodyJson, post); //调用泛型方法 RootEntity<NewEntity> data= parseNewsList(response, NewEntity.class); System.out.println("desc:"+data.getShowapi_res_body().getPagebean().getContentlist().get(0).getImageurls().size()); System.out.println("code:"+data.getShowapi_res_code()); System.out.println("error:"+data.getShowapi_res_error()); System.out.println("allnum:"+data.getShowapi_res_body().getPagebean().getAllNum()); System.out.println("allpages:"+data.getShowapi_res_body().getPagebean().getAllPages()); System.out.println("currentpages:"+data.getShowapi_res_body().getPagebean().getCurrentPage()); System.out.println("maxresult:"+data.getShowapi_res_body().getPagebean().getMaxResult()); }
