java.lang.NoSuchMethodError : com. mongodb.connection.DefaultClusterFactory.createCluster 错误

Question

我正在尝试将 MongoDB 与 Java 连接起来。这是我的代码

    MongoCredential mongoCredential;
    mongoCredential = MongoCredential.createCredential(<uname>, <dbname>, <password>);
    List<ServerAddress> list = Arrays.asList(new ServerAddress("localhost", 27017));

    MongoClientSettings.Builder mongoClientSettingsBuilder = MongoClientSettings.builder()
            .credential(mongoCredential)
            .applyToClusterSettings(builder -> builder.hosts(list));

    MongoClientSettings settings = mongoClientSettingsBuilder.build();      

执行这个我得到错误

Exception in thread "main" java.lang.NoSuchMethodError: com.mongodb.connection.DefaultClusterFactory.createCluster(Lcom/mongodb/connection/ClusterSettings;Lcom/mongodb/connection/ServerSettings;Lcom/mongodb/connection/ConnectionPoolSettings;Lcom/mongodb/connection/StreamFactory;Lcom/mongodb/connection/StreamFactory;Ljava/util/List;Lcom/mongodb/event/CommandListener;Ljava/lang/String;Lcom/mongodb/MongoDriverInformation;Ljava/util/List;)Lcom/mongodb/connection/Cluster;

我不知道这是什么原因。有人可以帮我解决这个问题

这可能是系统检测到多个mongodb-driver jar文件引起的冲突和困惑。我只是通过禁用 mongodb-driver-sync 并在 pom.xml 中使用 spring-boot-starter-data-mongodb 来解决类似的问题--NoSuchMethodError，如下所示:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>
<!--        <dependency>-->
<!--            <groupId>org.mongodb</groupId>-->
<!--            <artifactId>mongodb-driver-sync</artifactId>-->
<!--            <version>4.2.3</version>-->
<!--        </dependency>-->
