java - 将 json 嵌套对象从 mongodb 映射到 java

Question

我使用virustotal API在我的mongodb上获取json对象 这是存储在 mongodb 对象中的 json 对象的样子:

如您所见，json 对象太复杂，无法从中获取给定值， 这是我到目前为止所尝试过的:

MongoClient mongo = new MongoClient("localhost", 27017);
        MongoDatabase database1 = mongo.getDatabase(db);
        MongoCollection<Document> collection1 = database1.getCollection(col);
        try (MongoCursor<Document> cursor = collection1.find().iterator()){

            while (cursor.hasNext()){
                Document doc = cursor.next();
                List list = new ArrayList(doc.values());
                System.out.println(list.get(1));
            }

        }

我在想也许有一种方法可以将所有这些 json 映射到 java 类，主要问题是 "scans" 因为有许多不同的扫描器，并且它没有针对为每个人创建一个java类模型， 我的问题是如何将 json 对象直接存储到 java 对象中，以便对返回的结果进行操作。

Answer 1

我将您的主要模型称为 Scan。您可以创建具有以下属性的 POJO(我们称之为扫描仪):
扫描仪名称、检测到的、版本、结果、更新；

扫描仪.java

private String scannerName;
private String detected;
private String version;
private String result;
private String update;

扫描.java

private String scan_id;
private List<Scanner> = new ArrayList<Scanner>();
private String sha1;
private String resource;
......
........

所以您的扫描模型现在有一个扫描仪列表。

使用吗啡就像这样:

@Embedded
private List<Scanner> scanner;

如果您没有在 java 驱动程序周围使用任何包装器，请尝试

private List<BasicDBObject>
