查询失败的错误代码13带有名称＆＃x27;未经授权＆＃x27;在MongoDB中查找查询

Question

我在Java J2EE应用程序中研究MongoDB驱动程序。以前，我们使用此依赖项：

<dependency>
    <groupId>org.mongodb</groupId>
        <artifactId>mongo-java-driver</artifactId>
        <version>3.4.2</version>
    </dependency>
<dependency>
    <groupId>org.mongodb.morphia</groupId>
    <artifactId>morphia</artifactId>
    <version>1.3.2</version>
</dependency>

现在我们使用

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-sync</artifactId>
    <version>4.6.1</version>
</dependency>

了一个admin数据库，其中一个包含文档的集合。 这样的先前的连接方法是这样实现的：

MongoClient mongoClient = new MongoClient(serverList, Arrays.asList(MongoCredential.createCredential(username, "admin", password.toCharArray())), builder.build());
Morphia morphia = new Morphia();
morphia.getMapper().getOptions().setMapSubPackages(true);
morphia.mapPackage(entitiesPackage);
Datastore datastore = morphia.createDatastore(mongoClient, "mycollection");

现在我们有：

CodecProvider pojoCodecProvider = PojoCodecProvider.builder().automatic(true).build();
CodecRegistry pojoCodecRegistry = CodecRegistries.fromRegistries(MongoClientSettings.getDefaultCodecRegistry(), CodecRegistries.fromProviders(pojoCodecProvider));
MongoClient client = MongoClients.create(uri);
MongoCollection collection = client.getDatabase("admin").withCodecRegistry(pojoCodecRegistry).getCollection("mycollection");

使用此连接字符串：

mongodb://<username>:<password>@<mongodb_server_address>:27017

此连接是可以的此语法：

collection.find(MyEntity.class).first(); 

我们有一个错误：

Caused by: java.lang.RuntimeException: com.mongodb.MongoQueryException: Query failed with error code 13 with name 'Unauthorized' and error message 'not authorized on admin to execute command { find: "mycollection", filter: {}, limit: 1, singleBatch: true }' on server mongodb_server_address:27017

    at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:87)
    ... 8 more

它不是凭据

我这样解决了我的问题：

连接字符串：

mongodb://<username>:<password>@<my_server_address>:27017/<dbname>?authSource=admin

CodecProvider pojoCodecProvider = PojoCodecProvider.builder().automatic(true).build();
CodecRegistry pojoCodecRegistry = CodecRegistries.fromRegistries(MongoClientSettings.getDefaultCodecRegistry(), CodecRegistries.fromProviders(pojoCodecProvider));
MongoClient client = MongoClients.create(uri);
MongoDatabse database = client.getDatabase(dbName).withCodecRegistry(pojoCodecRegistry);
