通义千问java sdk添加function call之后不返回数据

灵积的官方JavaSDK还不支持Tool调用，你可以试试我写的dashscope4j

函数调用示例

灵积在 2024-03-12 放出了函数调用的功能，当前支持的模型是大语言模型：qwen-turbo、qwen-plus、qwen-max、qwen-max-longcontext，下面是一个函数调用的示例：

假设我们有一个回显函数:echo

@ChatFn(name = "echo", description = "当用户输入echo:，回显后边的文字")
public class EchoFunction implements ChatFunction<EchoFunction.Echo, EchoFunction.Echo> {

    @Override
    public CompletableFuture<Echo> call(Echo echo) {
        return CompletableFuture.completedFuture(new Echo(echo.words()));
    }

    public record Echo(
            @JsonPropertyDescription("需要回显的文字")
            String words
    ) {

    }

}

我们可以通过以下代码来调用这个函数：

final var request = ChatRequest.newBuilder()
    .model(ChatModel.QWEN_MAX)
    .functions(new EchoFunction())
    .user("echo: HELLO!")
    .build();
final var response = client.chat(request)
    .async()
    .join();
