如何在 Webflux 应用程序上使用反应式和非反应式 MongoDB 模板

目前，我正在为我的项目开发一个 springboot webflux 应用程序，在那里我使用reactive-mongo-template 和其他reactive 实现。现在我有一个由 WebMvc 实现的传统 spring boot 应用程序（这里我不使用真正的 springboot 应用程序。只使用使用 mongoDB 配置实现的核心服务）并且它使用（正常）mongo-template 来实现其实现的服务。在我的 webflux 应用程序中，我尝试使用旧应用程序中定义的旧服务。

为此，我尝试使用组件扫描 ( com.a.b.cservice.core.configuration)导入旧版应用程序，但出现了一些错误。问题是它不会正确检测应用程序和非反应式 mongo 模板。

弹簧是否仅支持 1 个 mongo 连接？这些是我得到的错误日志；

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    com.mongodb.connection.DefaultClusterFactory.createCluster(DefaultClusterFactory.java:182)

The following method did not exist:

    com.mongodb.connection.ClusterSettings.getDescription()Ljava/lang/String;

The method's class, com.mongodb.connection.ClusterSettings, is available from the following locations:

    jar:file:/C:/Users/abc/.m2/repository/org/mongodb/mongodb-driver-core/4.0.5/mongodb-driver-core-4.0.5.jar!/com/mongodb/connection/ClusterSettings.class
    jar:file:/C:/Users/abc/.m2/repository/org/mongodb/mongo-java-driver/3.12.7/mongo-java-driver-3.12.7.jar!/com/mongodb/connection/ClusterSettings.class

The class hierarchy was loaded from the following locations:

    com.mongodb.connection.ClusterSettings: file:/C:/Users/abc/.m2/repository/org/mongodb/mongodb-driver-core/4.0.5/mongodb-driver-core-4.0.5.jar


Action:

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

是否有任何解决方法可以使用带有 mongoDb 的 webflux 应用程序处理旧应用程序？或者我是否需要将其保留为单独的微服务并调用相关端点？
