Spring 引导 2.0.5.RELEASE 和 mongo 4.0 连接问题
Spring boot 2.0.5.RELEASE and mongo 4.0 connection issues
我正在关注 Spring web site
上的使用 MongoDB 访问数据教程
我安装了 Mongo 数据库服务器版本 4 作为服务
当我使用客户端连接到它时，它的身份验证工作正常。
我面临以下问题：
MongoCommandException: Command failed with error 18: 'Authentication failed'
我看到代码使用的 mongodb-driver-core-3.6.4.jar 与服务器版本 4
不兼容
如何只升级驱动而不破坏工程？
为什么他们使用 spring-boot-starter-data-mongodb 而不是 mongodb-driver-sync ?

我从我的 M2 文件夹
中删除了所有 mongodb 个罐子
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：

在eclipse之外运行很好，
在命令行中我做了：
mvn package
cd target
java -jar .\demo-0.0.1-SNAPSHOT.jar
它 运行 很好，不确定 Eclipse 中的问题是什么。
我认为 Overriding dependency versions with Spring Boot 上的这篇文章会对您有所帮助。 reactor 替换为 mongodb。 MongoDB 驱动程序本身几乎是向后兼容的，因此强制更新版本应该不会有任何大问题。
查看spring boot提示的方法未找到日志
com.mongodb.connection.DefaultClusterFactory.createCluster(

Ljava/util/List;)Lcom/mongodb/connection/Cluster;
注意第 7 个参数 Lcom/mongodb/client/MongoDriverInformation。 MongoDriverInformation class 从 com/mongodb/client 到 com/mongodb 在 3.7 之后的版本中已经 moved。
看来您的 class 路径上同时有 3.6.4 和 3.8.0 罐子。
因此请尝试清理您的 class 路径，并且 <mongodb.version>3.8.0</mongodb.version> 是覆盖 mongodb 依赖关系的正确方法，直到 spring 启动版本。
顺便说一句，有待定的 2.1.0 启动版本，它将 mongodb 依赖更新到 3.8.2 现在它是一个发布候选阶段。
我也遇到了这个问题。当我第一次添加 pom:
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver</artifactId>
<version>3.4.3</version>

编译项目后，出现：

所以这个问题很简单，网络上有很多方法可以解决，你只需要添加一个注解让spring boot ignore default mongo_properties:
@SpringBootApplication(exclude = MongoAutoConfiguration.class)
完成！
