Real PostgreSQL 16 and Redis Stack 7.4; 24 tests write output/01-24. Covers the 20-message default window with no property, the 36-character conversation_id, tool messages dropped by JdbcChatMemoryRepository, concurrent add() on one conversation, a 1.x table under the 2.0 repository, the Redis repository silently backing off for a custom ChatMemory, and the removal of PromptChatMemoryAdvisor.

spring-ai
Runnable companion code for the Spring AI articles on ankurm.com. One directory per module; each module is one commit and carries its own README, tests and captured output.
| Module | What it is | Article |
|---|---|---|
getting-started/ |
One ChatClient bean, three endpoints (plain call, templated system prompt, streaming), and a test proving spring.ai.model.chat switches providers with zero code change. Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. |
Spring AI 2.0 in 10 Minutes: ChatClient on Spring Boot 4.1 |
rag/ |
Ingest PDFs, chunk, retrieve from pgvector, rerank, answer, check the answer. Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. | Production-grade RAG with Spring AI and the complete example |
mcp-server/ |
An order-lookup service exposed as MCP tools, a resource, and a prompt with @McpTool/@McpResource/@McpPrompt, served over Streamable HTTP (Spring AI 2.0's default MCP server transport). Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. |
Build an MCP Server with Spring AI 2.0 |
mcp-client/ |
ChatClient calling tools from two real external MCP servers (filesystem, git) over stdio via defaultToolCallbacks(ToolCallbackProvider...), contrasted with a local @Tool method, with every call logged through one Micrometer ObservationHandler. Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. |
Spring AI MCP Client: Calling External MCP Servers from ChatClient |
mcp-secure/ |
The mcp-server article's order-lookup tools behind a real OAuth2 resource server: JWT validation, one scope per tool via @PreAuthorize, unauthenticated tool discovery rejected outright, and every call audit-logged through MDC -- denials included. Spring Boot 4.1.1, Spring AI 2.0.1, Spring Security 7.1.1, Java 25. |
Securing an MCP Server with Spring Security 7 |
tool-calling/ |
@Tool methods, ToolCallingAdvisor (the advisor-layer replacement for Spring AI 1.x's per-model tool loop), returnDirect, ToolContext, and ToolSearchToolCallingAdvisor for progressive disclosure across a 230-tool synthetic library -- every test driven by a hand-written ScriptedChatModel, no live model anywhere. Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. |
Tool Calling in Spring AI 2.0 |
structured-output/ |
ChatClient.entity() mapping LLM responses to Java records, lists and maps; StructuredOutputValidationAdvisor retrying non-conforming JSON with a real enum-constrained schema, including a captured run that exhausts every retry without throwing. Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. |
Structured Output in Spring AI 2.0 |
ollama-local/ |
Chat and embeddings against a real local qwen2.5:0.5b/all-minilm, no API key, driven by a Testcontainers-managed Ollama container started from a baked image; a confirmed model unload via keep_alive: 0 and /api/ps, not a scripted model anywhere. Spring Boot 4.1.1, Spring AI 2.0.1, Testcontainers 2.0.5, Java 25. |
Run LLMs Locally with Spring AI and Ollama |
chat-memory/ |
MessageChatMemoryAdvisor, MessageWindowChatMemory, the JDBC and Redis ChatMemoryRepository, per-user conversation IDs and a token-budget memory of our own, with the traps reproduced against a real PostgreSQL 16 and Redis Stack: a 36-character conversation_id, tool messages dropped on save, concurrent writers, a 1.x table under the 2.0 repository, and a Redis repository that silently steps aside for a custom ChatMemory. Spring Boot 4.1.1, Spring AI 2.0.1, Java 25. |
