Feature Request: Default Value Support in Lombok

Describe the feature
A clear and concise description of the feature request is to add support for setting default values in Lombok-generated getters. The goal of this feature request is to allow developers to specify default values for fields, ensuring that getters return these default values when the field is null.

Java Snippets:

import lombok.Getter;

public class MyClass {
    @Getter(defaultValue = BigDecimal.ZERO)
    private BigDecimal value; // Desired feature: Ability to specify default value, e.g., default = BigDecimal.ZERO
}

public class MyClass {
    private BigDecimal value;

    public BigDecimal getValue() {
        return value== null ? BigDecimal.ZERO : value;
    }
}

Describe the target audience
This feature proposal would benefit developers who use Lombok to reduce boilerplate code in their Java projects. It would particularly help those who need to ensure that getters return default values when the field is null.

Additional context
Adding support for default values in Lombok-generated getters would enhance the flexibility and convenience of using Lombok annotations, making it easier for developers to handle default values without manually writing getter methods. This feature would streamline the development process and improve code readability in projects utilizing Lombok.

Can I Implement This Feature Myself?
Certainly, you can implement this feature yourself by creating custom getter methods in your classes to handle default values. This approach provides flexibility in setting default values based on your specific needs and allows you to tailor the implementation to suit your requirements.

Why not use a field initializer?

Why not use a field initializer?

Because you can set it to null, and if you query the database, it will return null
