2 创建模型的 ChatClient

创建兼容 OpenAI API 的模型的 ChatClient 配置类，用于模型的调用。参考以下方法，可以为不同的模型创建不同的配置类。以火山引擎某模型为例，代码如下所示。

java 复制代码

@Configuration
public class OpenAIChatClientConfig {

    /**
     * 火山引擎模型baseUrl
     */
    @Value("${volces.baseUrl:test}")
    private String volcesBaseUrl;

    /**
     * 火山引擎模型apiKey
     */
    @Value("${volces.apiKey:test}")
    private String volcesApiKey;

    /**
     * 火山引擎模型-豆包模型v1
     */
    @Value("${volces.model.doubaoV1:test}")
    private String volcesModelDoubaoV1;


    // 获取火山引擎-豆包模型v1
    @Bean("chatClient4VolcesDoubaoV1")
    public ChatClient createChatClient4VolcesDoubaoV1() {
        OpenAiApi baseOpenAiApi = OpenAiApi.builder()
                .baseUrl(volcesBaseUrl)
                .apiKey(volcesApiKey)
                .completionsPath("/chat/completions")
                .build();

        OpenAiChatModel chatModel = OpenAiChatModel.builder()
                .openAiApi(baseOpenAiApi)
                .defaultOptions(OpenAiChatOptions.builder()
                        .model(volcesModelDoubaoV1)
                        .temperature(0.7)
                        .build())
                .build();

        return ChatClient.builder(chatModel)
                .defaultAdvisors()
                .defaultTools()
                .build();
    }


}

3 模型应用

使用上述创建的模型的 ChatClient，就可以进行模型的调用了。示例代码如下所示。

java 复制代码

@Slf4j
@RestController
@RequestMapping("/openai")
public class OpenAIChatClientController {
    private static final String DEFAULT_PROMPT = "你好，介绍下你自己！";

    @Resource
    private ChatClient chatClient4VolcesDoubaoV1;


    @GetMapping("/simple/chat")
    public String simpleChat(String prompt) {
        if (StringUtils.isBlank(prompt)) {
            prompt = DEFAULT_PROMPT;
        }
        String content;
        try {
            content = chatClient4VolcesDoubaoV1.prompt(prompt).call().content();
        } catch (Exception e) {
            log.error("simpleChat error", e);
            throw new RuntimeException(e.getMessage());
        }
        log.info("simpleChat --> \n prompt ={}, \n content = {}", prompt, content);
        return content;
    }


}
