JAVAlang.NoSuchMethodError:com。mongodb。联系DefaultClusterFactory。createCluster

Question

我正在尝试将MongoDB与Java连接起来。这是我的密码

    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();      

执行此操作时，我会得到错误

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。有人能帮我吗

这可能是由系统检测到的几个mongodb驱动程序jar文件引起的冲突和混乱。我只是通过禁用mongodb驱动程序同步和在pom中使用spring boot starter数据mongodb解决了类似的问题。类似于以下内容的xml：

        <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> >
