应用配置

spring:
  application:
    name: jackal-spring-ai
  ai:
    openai:
      api-key: ${DEEPSEEK_KEY}
      base-url: "https://api.deepseek.com"
      chat:
        options:
          model: deepseek-chat

• 这里使用了DeepSeek大模型，去 DeepSeek官网 获取API-KEY。
• 模型名也是从DeepSeek官方文档中获取。

核心代码实现

Service 层

@Service
public class ChatService {

    private final ChatClient chatClient;
    private final ChatModel chatModel;

    public ChatService(ChatClient.Builder chatClientBuilder, ChatModel chatModel) {
        this.chatClient = chatClientBuilder.build();
        this.chatModel = chatModel;
    }

    public String chatByModel(String input) {
        return chatModel.call(new Prompt(input)).getResult().getOutput().getText();
    }

    public String chatByClient(String input) {
        return chatClient.prompt().user(input).call().content();
    }
}

• Spring AI 会自动注入 ChatModel，这里注入的是DeepSeek的实现

Controller 层

@RestController
@RequestMapping("/ai")
@RequiredArgsConstructor
public class SpringAiController {
    public final ChatService chatService;

    @PostMapping("/chat/model")
    public String chatByModel(String input) {
        return chatService.chatByModel(input);
    }

    @PostMapping("/chat/client")
    public String chatByClient(String input) {
        return chatService.chatByClient(input);
    }
}
