通过以下代码恢复的表的列表：
package Stat;
public class Stats {
public static void main(String[] args) throws IOException, JSONException {
private static final Pattern PATTERN = Pattern.compile("id=(\\w*)}");
try {
@SuppressWarnings("resource")
MongoClient client = new MongoClient("localhost", 27017);
MongoDatabase database = client.getDatabase("stats");
MongoCollection<Document> collection = database.getCollection("stats");
// System.out.println("DB Connexion");
List<Document> stats = (List<Document>) collection.find().into(new ArrayList<Document>());
// System.out.println("Collecion Récupéré"+ stats);
for (Document result : stats) {
@SuppressWarnings("unchecked")
List<Document> results = (List<Document>) result.get("results");
Document objDoc = null;
for (Document doc : results) {
if (doc.containsKey("googContentType")) {
objDoc = doc;
String objStr= objDoc.toString();
//System.out.println("" + objStr);
ArrayList<String> myList = new ArrayList<String>(Arrays.asList(objStr.split(",")));
System.out.println(myList);
String getId(String element) {
Matcher matcher = PATTERN.matcher(element);
if (matcher.find()) {
return;
}
return;
Map<String, List<String>> table = myList.stream().collect(Collectors.groupingBy(Stats::getId));
}
}
}
}}catch (UnknownException e) {
e.printStackTrace();
}
**列表已恢复： [Document {{googContentType = realtime，id = ssrc_1920071231_recv}}]
[Document{{googContentType=realtime, id=ssrc_3180255579_send}}]
[Document{{googContentType=realtime, id=ssrc_1920071231_recv}}]
[Document{{googContentType=realtime, id=ssrc_3180255579_send}}]
我正在尝试对同一表上具有相同键ID的表进行如下分类： 表1 =
[
[Document{{googContentType=realtime, id=ssrc_1920071231_recv}}]
[Document{{googContentType=realtime, id=ssrc_1920071231_recv}}]
]
table 2=
[
[Document{{googContentType=realtime, id=ssrc_3180255579_send}}]
[Document{{googContentType=realtime, id=ssrc_3180255579_send}}]
]**
