正如您在这两个文档中看到的，大多数值都是重复的，当我获取和解析这些数据时，我必须跳过向jsonobject添加重复的服务

到目前为止，我已经做了以下事情

           List<JSONObject>  serviceNodeList = new ArrayList<JSONObject>();
            JSONObject jsonObj = new JSONObject("read json data);
            JSONArray array = jsonObj.getJSONObject("hits").getJSONArray("hits");

            for (int i = 0; i < array.length(); i++) {

                JSONObject innerObj = array.getJSONObject(i);
                String host = innerObj.getJSONObject("_source").getString("host");
                JSONArray serviceList = innerObj.getJSONObject("_source").getJSONArray("services");

                for (int j = 0; j < serviceList.length(); j++) {
                    JSONObject serviceObject2 = new JSONObject();
                    JSONObject serviceObj = serviceList.getJSONObject(j);
                    String service = (String) serviceObj.get("service");
                    String port = serviceObj.getString("port");
                    String protocol = serviceObj.getString("protocol");


                        System.out.println(serviceObj.get("service"));
                        System.out.println("-----------");
                        list.add(obj);
                        serviceObject2.put("shape", "image");
                        serviceObject2.put("label", service);
                        File f = new File("images/" + service + ".png");
                        serviceObject2.put("image", "images/Circle-icon.png");
                        serviceObject2.put("widthMin", 15);
                        serviceObject2.put("widthMax", 15);
                        serviceObject2.put("x", 100);
                        serviceObject2.put("y", 100);
                        serviceObject2.put("title", "Server/Host: " + host + "\n" + "Port :" + port);
                        serviceObject2.put("value", 1);
                        serviceObject2.put("port", port);
                        serviceObject2.put("protocol", protocol);
                        serviceNodeList.add(serviceObject2);





                }



            }

List serviceNodeList=new ArrayList（）；
JSONObject jsonObj=新的JSONObject（“读取json数据”）；
JSONArray数组=jsonObj.getJSONObject（“hits”）.getJSONArray（“hits”）；
对于（int i=0；i


在这里，我不想向jsonObject添加重复的服务。
如果我理解正确，您不想添加下面这样的服务，因为这些服务对于每个主机都是重复的
       {
          "port": "80",
          "protocol": "tcp",
          "status": "open",
          "service": "http"
        }

您可以获取java.util.HashSet，并在集合中不断添加密钥（比如“http”）。对于您读取的每个服务，您可以将检查
List<JSONObject>  serviceNodeList = new ArrayList<JSONObject>();
JSONObject jsonObj = new JSONObject("read json data);
JSONArray array = jsonObj.getJSONObject("hits").getJSONArray("hits");

Set<String> keys = new HashSet<String>(); //Create hash set

for (int i = 0; i < array.length(); i++) {
    JSONObject innerObj = array.getJSONObject(i);
    String host = innerObj.getJSONObject("_source").getString("host");

    JSONArray serviceList = innerObj.getJSONObject("_source").getJSONArray("services");

    for (int j = 0; j < serviceList.length(); j++) {

        JSONObject serviceObj = serviceList.getJSONObject(j);
        String service = (String) serviceObj.get("service");
        String port = serviceObj.getString("port");
        String protocol = serviceObj.getString("protocol"); 

        if(!keys.contains(service)){ //Check key for existance in set so that you avoid duplicates service. You should create set key based on how you want to avoid duplicate
            JSONObject serviceObject2 = new JSONObject();

            System.out.println(serviceObj.get("service"));
            System.out.println("-----------");
            list.add(obj);
            serviceObject2.put("shape", "image");
            serviceObject2.put("label", service);
            File f = new File("images/" + service + ".png");
            serviceObject2.put("image", "images/Circle-icon.png");
            serviceObject2.put("widthMin", 15);
            serviceObject2.put("widthMax", 15);
            serviceObject2.put("x", 100);
            serviceObject2.put("y", 100);
            serviceObject2.put("title", "Server/Host: " + host + "\n" + "Port :" + port);
            serviceObject2.put("value", 1);
            serviceObject2.put("port", port);
            serviceObject2.put("protocol", protocol);
            serviceNodeList.add(serviceObject2);

            keys.add(service); //Add key to set
        }
    }
}

List serviceNodeList=new ArrayList（）；
JSONObject jsonObj=新的JSONObject（“读取json数据”）；
JSONArray数组=jsonObj.getJSONObject（“hits”）.getJSONArray（“hits”）；
Set keys=new HashSet（）//创建哈希集
对于（int i=0；i
如果我理解正确，您不想添加下面这样的服务，因为这些服务对于每个主机都是重复的
       {
          "port": "80",
          "protocol": "tcp",
          "status": "open",
          "service": "http"
        }

您可以使用java.util.HashSet，并在集合中不断添加键（比如“http”）。对于您阅读的每一项服务，您可以在
List<JSONObject>  serviceNodeList = new ArrayList<JSONObject>();
JSONObject jsonObj = new JSONObject("read json data);
JSONArray array = jsonObj.getJSONObject("hits").getJSONArray("hits");

Set<String> keys = new HashSet<String>(); //Create hash set

for (int i = 0; i < array.length(); i++) {
    JSONObject innerObj = array.getJSONObject(i);
    String host = innerObj.getJSONObject("_source").getString("host");

    JSONArray serviceList = innerObj.getJSONObject("_source").getJSONArray("services");

    for (int j = 0; j < serviceList.length(); j++) {

        JSONObject serviceObj = serviceList.getJSONObject(j);
        String service = (String) serviceObj.get("service");
        String port = serviceObj.getString("port");
        String protocol = serviceObj.getString("protocol"); 

        if(!keys.contains(service)){ //Check key for existance in set so that you avoid duplicates service. You should create set key based on how you want to avoid duplicate
            JSONObject serviceObject2 = new JSONObject();

            System.out.println(serviceObj.get("service"));
            System.out.println("-----------");
            list.add(obj);
            serviceObject2.put("shape", "image");
            serviceObject2.put("label", service);
            File f = new File("images/" + service + ".png");
            serviceObject2.put("image", "images/Circle-icon.png");
            serviceObject2.put("widthMin", 15);
            serviceObject2.put("widthMax", 15);
            serviceObject2.put("x", 100);
            serviceObject2.put("y", 100);
            serviceObject2.put("title", "Server/Host: " + host + "\n" + "Port :" + port);
            serviceObject2.put("value", 1);
            serviceObject2.put("port", port);
            serviceObject2.put("protocol", protocol);
            serviceNodeList.add(serviceObject2);
