Resolution
When the MongoDB driver is included in the classpath of a Spring Boot application, Spring Boot will automatically try to connect to a MongoDB server. This assumes that the server is accessible locally at the default host (localhost) and port (27017). If the MongoDB server is not running or not available at the specified location, this attempt results in an error.
To enable auto-configurations for databases in a Spring Boot application, including the relevant database driver dependencies is essential. Specifically, for MongoDB, including the mongo-java-driver is sufficient, and Spring Boot will handle most configurations automatically. For other databases, we must include the corresponding driver dependencies and configure connection properties as well. If we wish to exclude certain auto-configurations, we can use the spring.autoconfigure.exclude property, specifying the fully qualified names of the classes we want to exclude.
For example, to exclude MongoDB auto-configuration, we can set spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration.
To disable MongoDB auto configuration please follow below steps:
1. Stop Registry Service
2. Delete all Registry log files.
3. Add below property in RegistryService.vmoptions
-Dspring.autoconfigure.exclude=org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration
4. Start Registry service.
Will not see the exception messages in the log file.
