java - Spring boot 2.0.5.RELEASE 和 mongo 4.0 连接问题

问题描述

我正在关注Spring 网站
上的使用 MongoDB 访问数据教程 我将 Mongo DB 服务器版本 4 作为服务安装了
当我使用 aa 客户端连接到它时，它的身份验证工作正常。

我面临以下问题： 

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

我看到代码使用的是与服务器版本 4 不兼容的 mongodb-driver-core-3.6.4.jar

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

更新
maven dependency-plugin show dependency on mongodb:mongodb-driver-core:jar:3.8.0
所以我不确定这个 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 jar
，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:

    file:/C:/Users/winUser/.m2/repository/org/mongodb/mongodb-driver-core/3.8.0/mongodb-driver-core-3.8.0.jar


Action:

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

更新 3

它在 Eclipse 之外运行良好，
在命令行中我做了：

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。

标签： javamongodbspring-bootspring-mongo

解决方案

查看spring boot呈现的method not found log。

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;

注意第 7 个参数 Lcom/mongodb/client/MongoDriverInformation。MongoDriverInformation 类已经moved从 com/mongodb/client 到 com/mongodb 在 3.7 以上版本。

因此，您的类路径中似乎同时具有 3.6.4 和 3.8.0 jar。

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

顺便说一句，有待发布的 2.1.0 启动版本会将 mongodb 依赖项更新到 3.8.2 现在它是一个发布候选阶段。
