AIGC盛行，带你轻松调用开发

前言

本篇文章基于java和阿里云的通义千问大模型手把手带你使用AIGC开发，实现文本对话和图像分析。

一、📖AIGC简介

你知道什么是AIGC吗？不知道？没关系，我来告诉你：

• AIGC就是由AI自动创作生成的内容（AI Generated Content），比如图片、视频、音乐、文字等。AIGC就像一支神奇的画笔，拥有无限的创造力。这支画笔的特别之处在于，它是由AI打造的。AI利用它的理解力、想象力和创作力，根据指定的需求和风格，创作出各种内容：文章、短篇小说、报告、音乐、图像，甚至是视频。AIGC的出现，打开了一个全新的创作世界，为人们提供了无数的可能性。
• AI，就是人工智能。它的目标是让机器能够像人一样有智能，能够看、听、说、想、做。要实现这个目标，AI需要用到重要的技术：深度学习、NLP（自然语言处理）、神经网络和生成式对抗网络（GAN）。

🌤️通过上面的讲诉，无论你曾经不知道还是模棱两可，现在应该大概了解了，下面带你走进AIGC，用程序员的身份打开AIGC。

二、📣开通体验

开通模型获取API-KEY

大家不要害怕开通不会产生收费，本文讲述的完全是免费就可使用的方法。

登录阿里云进入控制台后，鼠标移到下图位置

然后出现如下界面，找到人工智能与机器学习下的模型服务灵积，点击

参照开发文档，开通DashScope并创建API-KEY

总结文档上的开通步骤如下：

在控制台中点击总览，去开通

立开通（大家不要怕，这是不会产生扣费的）

开通后，点击 管理中心 的 API-KEY 菜单项，然后创建新的API-KEY

就会有个Accesskeyid和Secret值（这俩值要记住真正的开发中有用，本文章没用到）的弹窗，然后点击已创建的AIP-KEY查看并复制，这个会用到。

三、📝基于java实现调用

📣打开IDEA，开始操作了

1.设置API-KEY

先了解以下如何设置API-KEY值的：

import com.alibaba.dashscope.utils.Constants;
Constants.apiKey="这就是你的API-KEY的值（上面复制的）";

2.体验大语言模型

多轮对话演示

创建一个测试类：

代码如下：

import com.alibaba.dashscope.aigc.generation.Generation;
import com.alibaba.dashscope.aigc.generation.GenerationResult;
import com.alibaba.dashscope.aigc.generation.models.QwenParam;
import com.alibaba.dashscope.common.Message;
import com.alibaba.dashscope.common.MessageManager;
import com.alibaba.dashscope.common.Role;
import com.alibaba.dashscope.exception.ApiException;
import com.alibaba.dashscope.exception.InputRequiredException;
import com.alibaba.dashscope.exception.NoApiKeyException;
import com.alibaba.dashscope.utils.Constants;
import com.alibaba.dashscope.utils.JsonUtils;
import org.mockito.internal.matchers.Contains;

import java.awt.*;


class test {
    public static void callWithMessage()
            throws NoApiKeyException, ApiException, InputRequiredException {
        // 设置API-KEY值
        Constants.apiKey="你的API-KEY值";
        Generation gen = new Generation();
        MessageManager msgManager = new MessageManager(10);
        Message systemMsg =
                Message.builder().role(Role.SYSTEM.getValue()).content("You are a helpful assistant.").build();//告知模型他是个助手（设置角色）
        Message userMsg = Message.builder().role(Role.USER.getValue()).content("你好，周末去哪里玩？").build();//对话问题
        msgManager.add(systemMsg);
        msgManager.add(userMsg);
        QwenParam param =
                QwenParam.builder().model(Generation.Models.QWEN_PLUS).messages(msgManager.get())
                        .resultFormat(QwenParam.ResultFormat.MESSAGE)
                        .topP(0.8)
                        .enableSearch(true)
                        .build();
        GenerationResult result = gen.call(param);
        System.out.println(result);//输出回复
        msgManager.add(result);
        System.out.println(JsonUtils.toJson(result));//JSON格式输出回复
        param.setPrompt("找个近点的");//继续问题
        param.setMessages(msgManager.get());
        result = gen.call(param);
        System.out.println(result);
        System.out.println(JsonUtils.toJson(result));
    }


    public static void main(String[] args){
        try {
            callWithMessage();
        } catch (ApiException | NoApiKeyException | InputRequiredException e) {
            System.out.println(e.getMessage());
        }
        System.exit(0);
    }
}

上诉代码就是向模型提问周末去哪玩，模型给出回复后，又继续说让他说个近点的地方

总结

上面就是使用java调用通义千问大模型的案例，上诉代码都可以运行，如果想改变问题，就将对话问题修改就行。如果再自己写一个UI界面的话，你就拥有了自己的AIGC了（虽然是调用的API🌤️）。文章来源地址https://www.toymoban.com/news/detail-763963.html
