intermediateSpring AI — Core, ChatClient & RAG
How does Spring AI's structured output work? How do you map LLM responses to POJOs?
Call .call().entity(MyClass.class) — Spring AI generates a JSON schema from the class, adds it as instructions in the prompt, and parses the response back into that type (backed by BeanOutputConverter). For lists, use .entity(new ParameterizedTypeReference<List<X>>(){}). Eliminates brittle manual string parsing.
