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.

# A tool that throws (ORD-500 raises IllegalStateException: order database unavailable)
|
|
|
|
Case 1: a well-behaved model. It asks for the tool once, then answers from whatever the tool message says.
|
|
Spring AI : 2 requests, tool body ran 1 time(s). Tool message the model received: "order database unavailable"
|
|
answer: Done: order database unavailable
|
|
LangChain4j : 2 requests, tool body ran 1 time(s). Tool message the model received: "order database unavailable"
|
|
answer: Done: order database unavailable
|
|
|
|
Case 2: an insistent model. It asks for the tool again after every result. The server stops it with an HTTP 500 after 30 requests.
|
|
Spring AI : 31 requests, tool body ran 30 time(s)
|
|
exception InternalServerException: 500: cutoff reached
|
|
LangChain4j : 31 requests, tool body ran 30 time(s)
|
|
exception InternalServerException (root: HttpException): {"error":{"message":"cutoff reached"}}
|
|
|
|
Case 3: the same insistent model, each framework asked to stop after 5 tool rounds.
|
|
Spring AI (ToolCallingAdvisor + our MaxToolRounds(5) checker): 6 requests, tool body ran 5 time(s)
|
|
answer:
|
|
LangChain4j (maxSequentialToolsInvocations(5)) : 6 requests, tool body ran 5 time(s)
|
|
exception RuntimeException: Something is wrong, exceeded 5 tool calling round trips (maxToolCallingRoundTrips)
