Alibaba Extensions for Spring AI

This project builds upon Spring AI, providing extended implementations of core concepts such as ChatModel, ImageModel, AudioModel, MCP, DocumentParser, ChatMemory, ToolCallback, VectorStore, etc. It helps developers quickly integrate with Alibaba Cloud Bailian model services, vector database services, chat memory components, tool calling, and other features.

Based on these components, developers can use Spring AI ChatClient, or Spring AI Alibaba Agent Framework to quickly build their own AI agent applications. Please choose according to your specific use case.

Get Started

Prerequsites

1. Requires JDK 17+.
2. If there are any spring-ai dependency issue, please lean how to configure the spring-milestones Maven repository on FAQ page.

Use ChatClient to Develop a Chatbot

Add Dependencies

To quickly get started with Spring AI Alibaba, add 'spring-ai-alibaba-starter-dashscope' dependency to your java project.

<dependencyManagement>

Declare ChatClient

Decare a ChatClient instance that would have DashScopeChatModel automatically injected.

@RestController
@RequestMapping("/helloworld")
public class HelloworldController {
  private static final String DEFAULT_PROMPT = "你是一个博学的智能聊天助手，请根据用户提问回答！";
  private final ChatClient dashScopeChatClient;

  public HelloworldController(ChatClient.Builder chatClientBuilder) {
    this.dashScopeChatClient = chatClientBuilder
        .defaultSystem(DEFAULT_PROMPT)
        .defaultAdvisors(
            new SimpleLoggerAdvisor()
        )
        .defaultOptions(
            DashScopeChatOptions.builder()
                .withTopP(0.7)
                .build()
        )
        .build();
  }

  @GetMapping("/simple/chat")
  public String simpleChat(@RequestParam(value = "query") String query) {
    return dashScopeChatClient.prompt(query).call().content();
  }
}

Use Agent Framework to Develop an Agent

// TBD

Playground and Example

The community has developed a Playground agent that includes a complete front-end UI and back-end implementation. The Playground back-end is developed using Spring AI Alibaba and gives users a quick overview of all core framework capabilities such as chatbot, multi-round conversations, image generation, multi-modality, tool calling, MCP, and RAG.

You can deploy the Playground example locally and access the experience through your browser, or copy the source code and tweak it to your own business needs to build your own set of AI apps more quickly. For more examples, please refer to our official example repository: https://github.com/springaialibaba/spring-ai-alibaba-examples
