JUDO Dependency Injection FAQs

Question 1

What are JUDO Configuration Qualifiers?

Accepted Answer

Qualifiers are custom annotations used for type-safe configuration injection, allowing you to inject specific settings like 'RdbmsDaoChunkSize' or 'DispatcherEnableDefaultValidation' directly into your components.

Question 2

What is the benefit of the Provider pattern in JUDO?

Accepted Answer

The Provider pattern allows for the lazy creation of complex objects and provides a clean way to inject multiple dependencies into a single component without cluttering the main module configuration.

Question 3

Can I use this skill for integration testing?

Accepted Answer

Yes, the skill provides patterns for using the JUDO TestKit, which allows you to inject real or mocked dependencies into your services for robust integration and unit testing.

Question 4

How do I manage multiple implementations of an interface?

Accepted Answer

JUDO uses Guice Multibinders, which allow you to collect multiple implementations (like different security interceptors) into a single Set that can be injected and processed collectively.

Question 5

How do I override a default JUDO binding?

Accepted Answer

You can override bindings by passing a custom instance directly to the JudoDefaultModule builder or by creating a custom module that is installed after the default modules in the Guice injector.
