根据现有的API接口将获取JSON数据写入数据库

根据现有的API接口将获取JSON数据写入数据库

利用API将获取数据存入数据库

获取API的URl 的原则

例如网址API的网址为：https://wuliang.art/ncov/doc.html#/default/谣言/getRumorListUsingGET
注意：但是在你获取的URl为：http://wuliang.art/ncov/rumor/getRumorList?page=36
解释：
ncov/rumor/getRumorList：是API的接口名
page：参数

pom.xml文件导入

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.4</version>
        </dependency>
        <dependency>
            <groupId>org.jsoup</groupId>
            <artifactId>jsoup</artifactId>
            <version>1.12.1</version>
        </dependency>

第一步：创建相对应的类

比如谣言的类：

    private Integer id;

    private String dateRumor;

    private String explainRumor;

    private String author;

    private String abstractRumor;

    private String title;

    private String authordesc;

    private String idRumor;

注意：get、set别忘记了

    }

那么就可以用以下的代码块实现

   @RequestMapping("/rumor")
    public JSONObject rumor() throws Exception{

            CloseableHttpClient client = HttpClients.createDefault();
 //           for(int i=13;i<37;i++)
            String url = "http://wuliang.art/ncov/rumor/getRumorList?page=36";
            JSONObject jsonObject = null;
            HttpGet post = new HttpGet(url);
            try {
                post.addHeader("content-type", "text/xml");
                HttpResponse res = client.execute(post);
                if (res.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                    String result = EntityUtils.toString(res.getEntity());
                    jsonObject = JSONObject.parseObject(result);
            //        JSONObject jsonObject1= (JSONObject) jsonObject.get("data");
                List<Map<String,Object>> list = (List<Map<String, Object>>) jsonObject.get("data");
               for(Map<String,Object> map:list) {
                   RumorDo rumorDo = new RumorDo();
                   rumorDo.setDateRumor((String) map.get("date"));
                   rumorDo.setExplainRumor((String) map.get("explain"));
                   rumorDo.setAuthor((String) map.get("author"));
                   rumorDo.setAbstractRumor((String) map.get("abstract"));
                   rumorDo.setTitle((String) map.get("title"));
                   rumorDo.setAuthordesc((String) map.get("authordesc"));
                   rumorDo.setIdRumor((String) map.get("id"));

                   rumorService.insert(rumorDo);
               }

注意：data不是json数据中的
如果接口所返回的数据为：

{
  "code": 200,
  "message": "SUCCESS",
  "data": {
    "docs": [
      {
        "h5url": "https://h5.baike.qq.com/mobile/article.html?docid=tx20406001v3lknw&adtag=txxw.op.fybox",
        "image": "https://baike-med-1256891581.file.myqcloud.com/2020023/dec99f30-5843-11ea-b711-37db0881b500_0.jpg",
        "abs": "截至目前，NMPA共批准新冠病毒检测试剂15个，核酸检测试剂10个，抗体检测试剂5个。",
        "title": "15种新冠病毒检测获批，它们是如何检出病毒的？",
        "author_info": {
          "name": "",
          "icon": "https://baike-med-1256891581.file.myqcloud.com/yidian/production/common/image/source_wicon.png",
          "title": "",
          "department": "",
          "hospital": "腾讯医典医学团队"
        }
      },
      {
        "h5url": "https://h5.baike.qq.com/mobile/article.html?docid=tx204060015beohw&adtag=txxw.op.fybox",
        "image": "",
        "abs": "WHO将病毒传染给十人以上的患者定义为超级传播者。",
        "title": "1个感染10个，“超级传播者”如何防控？",
        "author_info": {
          "name": "",
          "icon": "https://baike-med-1256891581.file.myqcloud.com/yidian/production/common/image/source_wicon.png",
          "title": "",
          "department": "",
          "hospital": "腾讯医典医学团队"
        }
      }
    ],
    "count": 35
  }
}

那么所要获取的数据就要多一个：`

    @RequestMapping("/diagnosis")
    public JSONObject diagnosis() throws Exception{
       CloseableHttpClient client = HttpClients.createDefault();
        String url = "http://wuliang.art/ncov/news/getDiagnoseList?count=999";
        HttpGet post = new HttpGet(url);
        JSONObject jsonObject = null;
        try{
           post.addHeader("content-type","text/xml");
           HttpResponse res = client.execute(post);
           if(res.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
                String result = EntityUtils.toString(res.getEntity());
                jsonObject = JSONObject.parseObject(result);
                JSONObject jsonObject1= (JSONObject) jsonObject.get("data");
                List<Map<String,Object>> list = (List<Map<String, Object>>) jsonObject1.get("docs");
              for(Map<String,Object> map:list){
                 for(Map.Entry<String,Object> entry:map.entrySet()){
                     System.out.println("key:"+entry.getKey()+","+"value:"+entry.getValue());
                     Giagnosis giagnosis = new Giagnosis();
                     giagnosis.setH5url();
                 }
                   DiagnosisDo diagnosisDo =new DiagnosisDo();
                   diagnosisDo.setH5url((String) map.get("h5url"));
                  diagnosisDo.setImage((String) map.get("image"));
                 diagnosisDo.setAbs((String) map.get("abs"));
                   diagnosisDo.setTitle((String) map.get("title"));
                  //diagnosisDo.setAuthorInfo((String) map.get("author_info"));
                   System.err.println(map.get("h5url"));
                  //  diagnosisService.insert(diagnosisDo);

              }
           }

       }catch (Exception e){
           throw  new RuntimeException(e);
       }
        return jsonObject;
   }

注意：两个代码块的

第一个

  jsonObject = JSONObject.parseObject(result);
            //        JSONObject jsonObject1= (JSONObject) jsonObject.get("data");
                List<Map<String,Object>> list = (List<Map<String, Object>>) jsonObject.get("data");

第二个

  JSONObject jsonObject1= (JSONObject) jsonObject.get("data");
                List<Map<String,Object>> list = (List<Map<String, Object>>) jsonObject1.get("docs");
