Note on Spring AI vs LangChain4j Integration Testing Approach: + * + *

Unlike LangChain4j which favors programmatic model instantiation, Spring AI is designed around + * configuration-driven dependency injection and auto-configuration. The manual instantiation of + * Spring AI models (AnthropicChatModel, OpenAiChatModel, etc.) requires complex constructor + * parameters including: - API client instances with multiple configuration parameters - + * RetryTemplate, ObservationRegistry, ToolCallingManager - WebClient/RestClient builders and error + * handlers + * + *

This complexity demonstrates why Spring AI is typically used with Spring Boot + * auto-configuration via application properties: + * + * 

+ * spring.ai.anthropic.api-key=${ANTHROPIC_API_KEY}
+ * spring.ai.anthropic.chat.options.model=claude-3-5-sonnet-20241022
+ *
+ * + *

For ADK integration, the key value proposition is the configuration-driven + * approach where users can switch between providers (OpenAI, Anthropic, Ollama, etc.) by + * simply changing Spring configuration, without code changes. This is demonstrated in {@link + * SpringAIIntegrationTest} and {@link SpringAIConfigurationTest}. + * + *

Real-world production usage would typically involve Spring Boot applications where ChatModel + * beans are auto-configured and injected, making the SpringAI wrapper seamlessly work with any + * configured provider. + */ +class SpringAIRealIntegrationTest { + + /** + * This test demonstrates that SpringAI can work with any ChatModel implementation, including real + * providers when properly configured via Spring's dependency injection. + * + *

Subject: [PATCH 09/14] refactor: Remove empty doOnSubscribe callback in
 streaming

Removed the empty doOnSubscribe callback as backpressure is already
handled by BackpressureStrategy.BUFFER on the Flowable creation.
