编辑API和Key

application.yml:

spring:
  ai:
    openai:
      api-key: sk-xxxxx
      base-url: https://api.deepseek.com
      chat:
        options:
          model: deepseek-flash

使用

@Service
public class AiService {

    private final ChatClient chatClient;
    private final ObjectMapper objectMapper;

    // 注入 ChatClient.Builder
    public AiService(ChatClient.Builder builder) {
        this.chatClient = builder.build();
        this.objectMapper = new ObjectMapper();
    }

    /**
     * 接收 UserMessage 对象，不再接收原始字符串
     */
    public String simpleChat(UserMessage userMessage) {
        return chatClient.prompt()
                .messages(userMessage)
                .call()
                .content();
    }
}
