Same order assistant in both frameworks against a local fake OpenAI server: starter bean collision, wire differences, tool failure and loop bounds, observability meters, MCP-first tools, and a compile check of the 2025 article's snippets and Maven coordinates.

# The same order assistant in Spring AI and in LangChain4j, one question: "Where is ORD-1001?"
|
|
|
|
Spring AI : ChatClient.builder(model).defaultSystem(..).defaultTools(new SpringAiTools(orders))
|
|
LangChain4j: AiServices.builder(Support.class).chatModel(model).tools(new Lc4jTools(orders))
|
|
|
|
Spring AI answer : Done: "Order ORD-1001: Status=SHIPPED, ETA=2026-10-14"
|
|
LangChain4j answer : Done: Order ORD-1001: Status=SHIPPED, ETA=2026-10-14
|
|
HTTP requests sent : Spring AI 2, LangChain4j 2. Tool body executed: Spring AI 1, LangChain4j 1.
|
|
|
|
What differs on the wire (computed from the four bodies below):
|
|
top-level fields : Spring AI [messages, model, tools], LangChain4j [messages, model, stream, tools]
|
|
tool schema : Spring AI has $schema=true additionalProperties=true; LangChain4j has $schema=false additionalProperties=false
|
|
tool result message: Spring AI sent "\"Order ORD-1001: Status=SHIPPED, ETA=2026-10-14\"", LangChain4j sent "Order ORD-1001: Status=SHIPPED, ETA=2026-10-14"
