Inheriting from entity types causes failure when using entity-defined Regions

[yozaner1324]

Failure: The bean 'Person' could not be registered. A bean with that name has already been defined and overriding is disabled.

Scenario: This occurs when a class extends a data class annotated with @Region, even if the subclass is not used.

Example:

@Region("Person")
class Person{
    @Id
    private String name;
    public Person(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

class Customer extends Person {
    public Customer(String name) {
        super(name);
    }
}

If Customer doesn't extend Person, there is no issue, but if it does, the application context will fail to load.

Work arounds:

• Set spring.main.allow-bean-definition-overriding to true
• Don't use entity defined regions
• Don't inherit from data classes used to define regions.
