1： API json多层数据实体类封装（利用泛型技术）
RootEntity.java
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
public class PageBeanBody<T> {
private PageBean<T> pagebean;
private int ret_code;
//省略get set方法
}
PageBean.java
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
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
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());
}
