You can force LLM to give you structured output by passing a Record with your request. Spring AI will prompt LLM in the background to return proper JSON which satisfies a schema.

Start slowly and implement basic communication with the model first - system prompt, user message, AI message. Everything else builds on top of it.

You can leverage existing SpringBoot knowledge. It's configuration and Beans all the way down.

Spring AI is not a magic, it just unifies (as much as it's reasonable) different APIs of different models. Of course all major LLMs are supported.

This sounds even worse than everyone or a few people talking normally. At least in those cases ANC headphones are accepted. People whisper and they think nobody hears them while in reality some of us really do.

Usage of @DirtiesContext is most often a mistake! It will prevent test context caching and slow down your tests significantly.

For integration tests which need the whole app context use @SpringBootTest. Beware that they're much slower than sliced tests.

If you need to mock some dependencies (e.g. services when testing controllers) use @MockitoBean. Simple @Mock can't put the bean into Spring's context!

Spring Boot offers a few flavours of tests which don't start up the whole context but specific slices thereof. Some examples are: @WebMvcTest, @RestClientTest, @DataJpaTest… You'll probably write most tests of these types.

Tools like JUnit, Mockito, AssertJ (or Hamcrest), JsonAssert are the basics and you should be comfortable using them. Spring Boot specific testing is built on top of those.
