By default elements in a PlantUML generated diagram have shadows. To disable shadows we must set the skin parameter shadowing to the value false. PlantUML will then not create shadows on elements.
In the following sample PlantUML definition we use the value false for the skin parameter shadowing:
@startuml
' Remove shadows
skinparam shadowing false
actor User
[Third party application] as ThirdPartyApp
package "Spring Boot Application" {
rectangle Controllers <<Spring REST controllers>>
rectangle DataStoreService <<Spring service>>
rectangle Repository <<Spring repository>>
}
User --> Controllers
ThirdPartyApp --> Controllers
Controllers --> DataStoreService
DataStoreService --> Repository
@enduml
The generated diagram has no shadows:
