Question

我尝试过的事情：

InetAddress address = InetAddress.getByName("MyPCName");

MongoClientOptions.Builder builder = MongoClientOptions.builder().connectTimeout(3000);
MongoClient mongo = new MongoClient(new ServerAddress(address.getHostAddress(), 3001), builder.build());
        try {
            mongo.getAddress();
        } catch (Exception e) {
            System.out.println("Mongo is down");
            mongo.close();
        }

第二次尝试：

InetAddress address = InetAddress.getByName("MyPCName");
MongoClientURI uri = new MongoClientURI( "mongodb://"+address.getHostAddress()+":27017/"+TEST_SKETCH_APP );

MongoClient instance = MongoDatabaseConnection.getInstance(uri);
try {
            instance .getAddress();
        } catch (Exception e) {
            System.out.println("Mongo is down");
            instance .close();
        }

FireWall配置正确：

netsh advfirewall firewall add rule name="Allowing mongod" dir=in action=allow program=" C:\Program Files\MongoDB\Server\3.2\bin\mongod.exe"

但是当我尝试连接以执行插入操作时，我收到此错误消息：

Timed out after 3000 ms while waiting to connect. Client view of cluster state is {type=Unknown, servers=[{address=192.168.138.1:3001, type=Unknown, state=Connecting}]

我正在AsyncTask中执行保存操作。我的mongo数据库服务器正在＆＃34; MyPCName＆＃34;电脑。我的Mongodb配置也有绑定ip评论。我也试过绑定Ip来保持这个bind_ip = 127.0.0.1,***.***.***.*,0.0.0.0 ＆＃39; *＆＃39; mark是我执行address.getHostAddress()时获得的IP地址。

我现在被困在这里。

试试这段代码：

MongoClientURI mongoUri  = new MongoClientURI("mongodb://Dbuser:dbpass@ds047692.mongolab.com:47692");
MongoClient mongoClient = new MongoClient(mongoUri);
DB db = mongoClient.getDB("testdb");
Set<String> collectionNames = db.getCollectionNames();
