Question

我正在遵循Spring web site上的《使用MongoDB访问数据》教程
我已将Mongo DB Server版本4安装为服务当我使用客户端连接到它时，它的身份验证工作正常。

我正面临以下问题：

MongoCommandException: Command failed with error 18: 'Authentication failed'

我看到代码正在使用与服务器版本4不兼容的mongodb-driver-core-3.6.4.jar

如何仅在不弄乱项目的情况下升级驱动程序？
为什么他们使用spring-boot-starter-data-mongodb而不是mongodb-driver-sync？

更新
Maven依赖插件显示对mongodb的依赖：mongodb-driver-core：jar：3.8.0
所以我不确定此mongodb-driver-core-3.6.4.jar来自哪里？

更新2
我从M2文件夹中删除了所有mongodb jars
并将mongodb属性添加到pom部分：

    <mongodb.version>3.8.0</mongodb.version>

现在我看到一个新错误：

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method 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/client/MongoDriverInformation;Ljava/util/List;)Lcom/mongodb/connection/Cluster; but it does not exist. Its class, com.mongodb.connection.DefaultClusterFactory, is available from the following locations:

    jar:file:/C:/Users/winUser/.m2/repository/org/mongodb/mongodb-driver-core/3.8.0/mongodb-driver-core-3.8.0.jar!/com/mongodb/connection/DefaultClusterFactory.class

It was loaded from the following location:

Action:

Correct the classpath of your application so that it contains a single, compatible version of com.mongodb.connection.DefaultClusterFactory

更新3

在日食之外运行良好，
在命令行中，我这样做了：

mvn package  
cd target
java -jar .\demo-0.0.1-SNAPSHOT.jar

它运行良好，不确定Eclipse中的问题是什么。

Answer 1

我也遇到了这个问题。当我第一次添加pom时：

    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongodb-driver</artifactId>
        <version>3.4.3</version>
    </dependency>

编译项目后，它发生了：

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method 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/client/MongoDriverInformation;Ljava/util/List;)Lcom/mongodb/connection/Cluster; but it does not exist. Its class, com.mongodb.connection.DefaultClusterFactory, is available from the following locations:

Action:
Correct the classpath of your application so that it contains a single, compatible version of com.mongodb.connection.DefaultClusterFactory

然后我纠正了pom，我解决了这个错误，但是我看到了另一个错误：这是新的pom，我认为这是由于mongo_version所致。

    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongodb-driver</artifactId>
        <version>3.8.0</version>
    </dependency>

这是新的警告：

所以这个问题很容易，网络有很多方法可以解决，您只需添加一个注释，让spring boot忽略默认的mongo_properties：

@SpringBootApplication(exclude = MongoAutoConfiguration.class)

然后完成！

Answer 2

看看spring boot提供的方法未找到日志。

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/client/MongoDriverInformation; Ljava/util/List;)Lcom/mongodb/connection/Cluster;

请注意第七个参数Lcom / mongodb / client / MongoDriverInformation。 MongoDriverInformation类已经从com / mongodb / client moved到3.7以后的com / mongodb版本。

因此看来您的类路径上同时有3.6.4和3.8.0 jar。

因此，请尝试清理您的类路径，并且<mongodb.version>3.8.0</mongodb.version>是在春季启动发行版之前覆盖mongodb依赖项的正确方法。

顺便说一句，还有一个即将发布的2.1.0引导版本，它将把mongodb依赖关系更新为3.8.2，现在是候选发布阶段。

Answer 3

我认为Overriding dependency versions with Spring Boot上的这篇文章会对您有所帮助。对于reactor，请替换为mongodb。 MongoDB驱动程序本身非常向后兼容，因此在强制使用新版本时应该不会有大问题。

Spring Boot 2.0.5.RELEASE和Mongo 4.0连接问题
