JAVA com.mongodb.MongoQueryException : Query failed with error code 13 and error message 'command find requires authentication'

Question

com.mongodb.MongoQueryException: Query failed with error code 13 and error message 'command find requires authentication'

如何在java中使用密码创建mongo客户端。

我知道有这样的方法:

public MongoClient(final ServerAddress addr, final List<MongoCredential> credentialsList);

但它显示为已弃用，还有另一种方法需要 MongoClientOptions:

public MongoClient(final ServerAddress addr, final MongoCredential credential, final MongoClientOptions options)

但我没有任何发送选项。那么，有什么方法可以使用密码在java中创建mongo客户端吗？

要执行 find 命令，您需要先通过 mongo 进行身份验证。如何进行身份验证的示例:

Mongo mongo = new Mongo("localhost", 27017);
DB db = mongo.getDB("testdb");

boolean auth = db.authenticate("testdb", "password".toCharArray());
if (auth) {

    DBCollection table = db.getCollection("user");

    BasicDBObject document = new BasicDBObject();
    document.put("name", "mkyong");
    table.insert(document);

    System.out.println("Login is successful!");
} else {
    System.out.println("Login is failed!");
}

这应该适合你。

您可以查看本文中的示例代码:https://www.mkyong.com/mongodb/java-authentication-access-to-mongodb/

当使用 mongo-java-driver 时，以下内容是合适的:- 请注意，这不再使用已弃用的方法，而是将 writeconcern 设置为 Journaled(推荐)

String username = "test";
String database = "something";
String password = "secret";

MongoCredential mongoCredential = MongoCredential.createCredential(username, database, password.toCharArray());
MongoClientOptions options = MongoClientOptions.builder()
.writeConcern(WriteConcern.JOURNALED).build();

MongoClient mongoClient = new MongoClient(new ServerAddress("host1", 27017), Arrays.asList(mongoCredential), options);
