You just have to:

• include the Spring AI dependencies
• provide an AI token
• call the Spring AI proxy (e.g. ChatClient, ImageClient)

Supported models are:

Chat Models

• OpenAI
• Azure Open AI
• Amazon Bedrock
• Anthropic’s Claude
• Cohere’s Command
• AI21 Labs’ Jurassic-2
• Meta’s LLama 2
• Amazon’s Titan
• Google Vertex AI Palm - Gemini support coming soon (follow the WIP branch)
• HuggingFace - access thousands of models, including those from Meta such as Llama2
• Ollama - run AI models on your local machine

The main challenge was finding suitable documentation, as many sources describe integration with AWS SDK version 1.x.

In true Scout’s honor, here’s a brief description of how to integrate DynamoDB using AWS SDK 2.x into a Spring Boot project.

In the project, start the following Docker container to have a local DynamoDB for development purposes. Here’s an excerpt from our docker-compose.yml:

This removes the necessity to create test docker-compose.yml files and write README.md code on how to even run a test.

Here is a short example using testcontainers with Spring and Spock on a Postgis / Postgres database.

@SpringBootTest
@AutoConfigureMockMvc
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@ContextConfiguration(initializers = [Initializer.class])
class FieldControllerTest extends IntegrationTest {

  @Shared
  public static JdbcDatabaseContainer postgreSQLContainer = new PostgisContainerProvider()
    .newInstance()
    .withDatabaseName("integration-tests-db")
    .withUsername("sa")
    .withPassword("sa");


  static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {

    void initialize(ConfigurableApplicationContext configurableApplicationContext) {
      postgreSQLContainer.start()
      TestPropertyValues.of(
        "spring.datasource.url=" + postgreSQLContainer.getJdbcUrl(),
        "spring.datasource.username=" + postgreSQLContainer.getUsername(),
        "spring.datasource.password=" + postgreSQLContainer.getPassword()
      ).applyTo(configurableApplicationContext.getEnvironment());
    }
  }

  @Autowired
  MockMvc mockMvc

  @Autowired
  FieldRepository fieldRepository

  void setup() {
    fieldRepository.save(new Field(
      UUID.fromString('ad68f894-c16b-4953-b577-7cddb3e85ae5'), "initSampleField",
      new Polygon(
        PositionSequenceBuilders.variableSized(G2D.class)
          .add(5.8208837124389, 51.0596004663904)
          .add(5.83490292265498, 51.0571257015788)
          .add(5.87078646658134, 51.0451607414904)
          .add(5.79146302423308, 51.0612386272784)
          .add(5.8208837124389, 51.0596004663904)
          .toPositionSequence(),
        CoordinateReferenceSystems.WGS84
      )
    ))
  }

  ...
}

To integrate testcontainers into your project, you’ll need the following dependencies:
