Exception while starting Spring boot with Embedded MongoDb

it fixes the issue Spring Boot will only automatically start an embedded Mongo instance if you're using 1.3.0. It got resolved once I updated the mongoDb starter to 1.3.1.
code :
compile 'org.springframework.boot:spring-boot-starter-data-mongodb:1.3.1.RELEASE'

Model validation exception with Spring Boot 2.0.2.RELEASE

I hope this helps you . So the issue is the following:
the constructor as provided by the reflection API is: com.test.simple.Group(java.lang.String $enum$name, int $enum$ordinal, java.lang.String groupName, java.lang.String groupDescription) so it has four parameters. I suppose the name and the ordinal are passed to the constructor; the parameter names as provided by KotlinReflectionParameterNameDiscoverer are only [groupName, groupDescription] (so not taking into account the additional parameters).

I hope this helps you . The @WebFluxTest test annotation is not importing the JSON auto-configuration in Spring Boot 2.x. There's an existing issue to fix that, see spring-boot#15070.

Upgraded spring boot from 2.1.9 to 2.2.0 , now getting exception while starting

hop of those help? In short, issue is due to spring cloud and spring boot version incompatibility, spring boot 2.2.X requires Hoxton release train instead of Greenwich. See below for more info.
This issue is due to spring-cloud.version incompatibility. As per spring cloud documentation link(https://spring.io/projects/spring-cloud), below is the spring boot compatibility:
code :
Release Train      Boot Version

  Hoxton             2.2.x

  Greenwich          2.1.x
