获取驱动包

maven 地址：<dependencies>    <dependency>        <groupId>org.mongodb</groupId>        <artifactId>mongodb-driver</artifactId>        <version>3.2.2</version>    </dependency></dependencies>

未启动安全检查模式:

private static void noAuth() {        MongoClientURI uri = new MongoClientURI("mongodb://localhost:27017", MongoClientOptions.builder().cursorFinalizerEnabled(false));        MongoClient client = new MongoClient(uri);        MongoDatabase db = client.getDatabase("test");        MongoCollection<Document> collection = db.getCollection("test.coll");        List<Document> foundDocument = collection.find().into(new ArrayList<Document>());        System.out.println(foundDocument);    }

启动安全检查：

private static void auth() {        MongoCredential credential = MongoCredential.createCredential("mxmx", "test", "mxmx".toCharArray());        MongoClient mongoClient = new MongoClient(new ServerAddress("localhost", 27017), Arrays.asList(credential));        MongoDatabase db=mongoClient.getDatabase("test");        MongoCollection<Document> collection=db.getCollection("test");        List<Document> foundDocument=collection.find().into(new ArrayList<Document>());        System.out.println(foundDocument);    }
