DashScope4j：灵积 Java SDK

DashScope4j 是一个开源的灵积非官方 Java SDK，基于 JDK17 构建。它旨在提供一个功能丰富、易于集成和使用灵积API（通义千问模型）的Java库，以便开发者能够通灵积API轻松实现多模态对话、向量嵌入和图像处理等功能。

请注意：在使用 DashScope4j 时，你需要遵守灵积API的使用条款和条件。

重要更新：1.2.0；支持函数调用

灵积在 2024-03-12 放出了 函数调用 功能，当前支持的模型是大语言模型 qwen-turbo、qwen-plus、qwen-max、qwen-max-longcontext，
DashScope4j 从 1.2.0 版本开始作为 Java SDK 首发支持函数调用

函数调用是我实际开发中最喜欢的一个功能，它扩展了大模型的能力边界，让AI具备了操纵现实的能力。而之前要做到这些事情我得通过 LangChain 来实现。

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：

单个函数调用示例：回显

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();

HELLO!

级联函数调用示例：成绩查询

我们有两个函数

• 查询成绩函数：query_score
• 计算平均分函数：compute_avg_score

现在需要查询某个同学的所有成绩，并计算其平均分。LLM需要先调用 query_score 函数查询成绩，然后再调用 compute_avg_score 函数计算平均分。

final var request = ChatRequest.newBuilder()
    .model(ChatModel.QWEN_PLUS)
    .functions(new QueryScoreFunction(), new ComputeAvgScoreFunction())
    .user("张三的所有成绩，并计算平均分")
    .build();
final var response = client.chat(request)
    .async()
    .join();
