Companion code for the ankurm.com guide. Verified on Spring AI 2.0.0, Spring Boot 4.1.0,
JDK 25.0.3. run.txt is unedited mvn test output: 5 tests, 0 failures.
Runs with NO API key, no network and no provider account. A canned ChatModel returns fixed
responses; ChatClient, advisors and chat memory all sit above the model, so everything that
changed is still exercised faithfully. TestChatModel records each Prompt it receives, which
lets the tests assert what Spring AI SENT rather than what a model replied.
docs/01 complete breaking-change reference: platform (Boot 4 mandatory, Jackson 2 to 3),
artifact renames (spring-ai-advisors-vector-store -> spring-ai-vector-store-advisor,
spring-ai-core split, OCI and Minimax removals, MCP transports moved into Spring AI),
options builders replacing setters, the dropped .options property prefix, tool
calling (internalToolExecutionEnabled and toolNames removed outright, not renamed),
chat memory, structured output schema changes, and a migration order that works.
Tested here
- Chat memory becomes stricter: 2.0 removes the remaining default-ID and builder-based
configuration paths (ChatMemory.DEFAULT_CONVERSATION_ID and .conversationId() are both
gone). Explicit per-request conversation ids - introduced during the 1.x line and already
the recommended approach - become the only migration target.
- CONVERSATION_ID survives as the metadata KEY. It and the removed DEFAULT_CONVERSATION_ID
look interchangeable and are opposites; swapping them to clear a compile error restores
exactly the shared-conversation behaviour that removing it was meant to take away.
- PromptChatMemoryAdvisor is gone; MessageChatMemoryAdvisor replaces it, and the difference
is not cosmetic (system-prompt text vs real Message objects, so token counts change).
- A test asserts two conversation ids cannot see each other.

Runs entirely offline. There is no API key, no network call and no model provider: a test
|
|
ChatModel returns canned responses, which is enough to exercise every API that changed.
