我是 Mongo DB 数据库的新手，需要帮助建立 JDBC 连接，我已按照在线提供的说明进行操作，但出现了一些错误。
import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import com.mongodb.ServerAddress;
import com.mongodb.MongoCredential;
import com.mongodb.MongoClientOptions;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import java.util.Arrays;
import org.bson.Document;
public class myMongoDbCollection {
public static void main( String args[] ) {
MongoClient mongoClient = new MongoClient ( new MongoClientURI("mongodb://Sudhanva:<password>@cluster0-shard-00-00-angnd.mongodb.net:27017,cluster0-shard-00-01-angnd.mongodb.net:27017,cluster0-shard-00-02-angnd.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true&w=majority"));
// Creating a Mongo client
// Creating Credentials
String user="Sudhanva"; // the user name
String database="SACCIDANANDA_DB"; // the name of the database in which the user is defined
String passwordtemp = "sudhanva123";
char[] password =passwordtemp.toCharArray();
MongoCredential credential = MongoCredential.createCredential(user, database, password);
mongoClient = new MongoClient (new ServerAddress(),Arrays.asList(credential));
MongoClientOptions options = MongoClientOptions.builder().sslEnabled(true).build();
MongoDatabase database1 = mongoClient.getDatabase("SACCIDANANDA_DB");
MongoCollection<Document> coll = database1.getCollection("DEVICE_REGISTRY");
for (String name : database1.listCollectionNames()) {
System.out.println(name);
}
}
}
我收到此错误 -
