AI - 人工智能;Java之SpringAI(二)

AI - 人工智能;Java之SpringAI(一)

一、开发SpringAI准备

1、访问OpenAI权限和API Key

(1)本机电脑要可以访问OpenAI网站 https://openai.com/;

(2)要有OpenAI的API Key;(注册账号或者购买)

例:API-Key:sk-xxxx1213xxxx23242xxxXXXX

在某宝上搜索 open ai api key,找到API key,购买之前请咨询清楚是直连还是转发地址?以及是否开发要用到的API key

2、开发SpringBoot和IDEA版本要求

‌*Spring AI的发布时间是2024年3月1日*‌‌

Spring AI是一个人工智能工程的应用框架,旨在为Java开发者提供一种更简洁的方式与AI交互,减轻在Java业务中接入LLM模型应用的学习成本。目前,Spring AI已经上架到Spring Initializr,开发者可以在https://start.spring.io/上使用并构建相关应用‌

‌使用SpringAI至少需要SpringBoot 3.2版本‌

SpringAI是Spring框架的一个新项目,旨在简化Java开发人员将AI功能集成到应用程序中的过程

使用SpringAI,需要确保开发环境满足以下2个要求:

1、JDK版本:JDK 17(含)以上‌

2、SpringBoot版本:3.2以上‌

3、IDEA2024版

此外,SpringAI支持接入多种AI服务,如OpenAI、Ollama、Azure OpenAI、Huggingface等,可以实现聊天、embedding、图片生成、语音转文字、向量数据库、function calling、prompt模板、outputparser、RAG等功能‌

1、创建SpringAI项目

选择Spring Boot 至少3.2版本;且勾选AI中的OpenAI选项(2024之前的老版本IDEA应该没有这个选项)

2、添加依赖;加入spring-ai-openai-spring-boot-starter依赖

    <repositories>
        <repository>

                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

Maven中心仓库搜不到这个依赖

3、配置yml文件

spring:
  application:
    name: spring-ai
  ai:
    openai:
      api-key: sk-8sfKHJ03KJG3SDFfsdf283JSwsf23lkjkHDND32fmGJHF  # 换成你自己的api-key
      base-url: https://api.openai.com  #如果是购买的转发地址,这边换成转发的OpenAI地址

4、编写测试类测试

(1)注入OpenAiChatModel

@Resource private OpenAiChatModel openAiChatModel;

注:刚开始发布的版本,这里是 OpenAiChatClient

(2)调用call方法 openAiChatModel.call(message);

package com.demo.springai1chat.controller;

import jakarta.annotation.Resource;
import org.springframework.ai.openai.OpenAiChatModel;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

/**
 * @description:
 * @author: zm
 */
@RestController
@RequestMapping("/ai")
public class ChatController {

    /**
     * spring-ai自动装配的,可以直接注入使用
     */
    @Resource
    private OpenAiChatModel chatModel;

    /**
     * OpenAI接口调用
     * @param message   提问信息
     * @return  OpenAI相应信息
     */
    @GetMapping("/chat")
    public String aiChat(@RequestParam("msg")String message) {
        return chatModel.call(message);
    }
}

自动装配(Auto-configuration )

添加了 spring-ai-openai-spring-boot-starter 依赖;Spring AI 为 OpenAI Chat Client 提供了 Spring Boot 自动装配。

OpenAiAutoConfiguration配置类中自动注入了,我们只需要直接注入调用即可

刚开始发布的SpringAI版本中,叫OpenAiChatClient

而该依赖中针对各个大模型提供了一个对应的自动配置类,如OpenAiAutoConfiguration,在该自动配置类中定义了以下几个Bean:

OpenAiChatModel/OpenAiChatClient(老版本):文字聊天客户端
OpenAiEmbeddingModel/OpenAiEmbeddingClient(老版本):文本向量化客户端
OpenAiImageModel/OpenAiImageClient(老版本):文生图客户端
OpenAiAudioTranscriptionModel/OpenAiAudioTranscriptionClient(老版本):语音转文字客户端

这些Bean在创建时就会构造底层连接OpenAi的客户端OpenAiApi对象,其中会用到以下几种配置:

OpenAiConnectionProperties:连接配置
OpenAiChatProperties:聊天配置
OpenAiEmbeddingProperties:向量化配置
OpenAiImageProperties:文生图配置
OpenAiAudioTranscriptionProperties:语音转文字配置

连接OpenAi的地址就apiKey就在OpenAiConnectionProperties中,比如application.properties的配置为:

spring.ai.openai.base-url=http://localhost:3000
spring.ai.openai.api-key=sk-xxxxx

5、启动调用访问 localhost:8080/ci/chat?msg=为我写一首歌http://localhost:8080/ai/chat?msg=为我写一首歌

二、AI聊天(OpenAiChatModel)

官网API文档:OpenAI Chat :: Spring AI Reference

1、application.yml配置文件

spring:
  application:
    name: spring-ai-01-chat
  ai:
    openai:
      api-key: ${OPENAI_API_KEY} # 换成你自己的api-key
      #如果是购买的转发地址,这边换成转发的OpenAI地址
      base-url: ${OPENAI_BASE_URL}  
      # 可选参数在配置文件中配置了,在代码中也配置了,则以代码的配置为准(代码的配置会覆盖掉配置文件中的配置)
      chat:
        options:
          # 当前默认版本 gpt-4o
          model: gpt-4-32k
          temperature: 0.4

在OpenAIChatOptions类中打上断点可以看到当前默认的版本

**2、测试类 **

package com.demo.springai1chat.controller;

import jakarta.annotation.Resource;
import org.springframework.ai.chat.model.ChatResponse;
import org.springframework.ai.chat.prompt.Prompt;
import org.springframework.ai.openai.OpenAiChatModel;
import org.springframework.ai.openai.OpenAiChatOptions;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;

/**
 * @description:
 * @author: zm
 */
@RestController
@RequestMapping("/ai")
public class ChatController {

    /**
     * spring-ai自动装配的,可以直接注入使用
     */
    @Resource
    private OpenAiChatModel chatModel;

    /**
     * OpenAI接口调用
     * @param message   提问信息
     * @return  OpenAI相应信息
     */
    @GetMapping("/chat")
    public String aiChat(@RequestParam("msg")String message) {
        String msgResp = chatModel.call(message);
        return msgResp;
    }

    /**
     * OpenAI接口调用
     * @param message   提问信息
     * @return  OpenAI相应信息
     */
    @GetMapping("/chat/prompt")
    public ChatResponse aiChatPrompt(@RequestParam("msg")String message) {
        ChatResponse chatResp = chatModel.call(new Prompt(message));
        //chatResp.getResult().getOutput().getContent();
        return chatResp;
    }

    /**
     * OpenAI接口调用
     * @param message   提问信息
     * @return  OpenAI相应信息
     */
    @GetMapping("/chat/option")
    public ChatResponse aiChatOptions(@RequestParam("msg")String message) {
        //可选参数在配置文件中配置了,在代码中也配置了,则以代码的配置为准(代码的配置会覆盖掉配置文件中的配置)
        ChatResponse chatResp = chatModel.call(new Prompt(message, OpenAiChatOptions.builder()
                .withModel("gpt-4-32k") //gpt的版本,32k是参数量(参数量越大,回答的问题质量越好,准确率越高)
                .withTemperature(0.4) //温度越高,回答得比较有创新性,但是准确率会下降,温度越低,回答的准确率会更好
                .build()));
        // chatResponse.getResult().getOutput().getContent();
        return chatResp;
    }

    /**
     * OpenAI接口调用
     * @param message   提问信息
     * @return  OpenAI相应信息
     */
    @GetMapping("/chat/stream")
    public Object aiChatStream(@RequestParam("msg")String message) {
        //可选参数在配置文件中配置了,在代码中也配置了,则以代码的配置为准(代码的配置会覆盖掉配置文件中的配置)
        Flux<ChatResponse> chatRespFlux = chatModel.stream(new Prompt(message, OpenAiChatOptions.builder()
                .withModel("gpt-4-32k") //gpt的版本,32k是参数量(参数量越大,回答的问题质量越好,准确率越高)
                .withTemperature(0.4) //温度越高,回答得比较有创新性,但是准确率会下降,温度越低,回答的准确率会更好
                .build()));
        chatRespFlux.toStream().forEach(chatResp ->
                System.out.println(chatResp.getResult().getOutput().getContent())
        );
        return chatRespFlux.collectList();
    }
}

【1】使用call参数‌:

call

方法用于同步获取模型响应

(1)创建Prompt 对象传入message参数

(2)使用 ChatOptionsBuilder#builder() 创建的可移植 ChatOptions 实例

2、使用stream参数‌:

stream

方法用于流式获取模型响应,适用于需要长时间处理或大量数据的场景

三、AI图片(OpenAiImageModel)

官网API文档:OpenAI Image Generation :: Spring AI Reference

**1、application.yml配置文件 **

spring:
  application:
    name: spring-ai-02-image

      #如果是购买的转发地址,这边换成转发的OpenAI地址
      base-url: ${OPENAI_BASE_URL}  
      # 可选参数在配置文件中配置了,在代码中也配置了,则以代码的配置为准(代码的配置会覆盖掉配置文件中的配置)
      image:
        options:
          model: dall-e-3
          quality: hd
          n: 1
          height: 1792

    @Resource
    private OpenAiImageModel openAiImageModel;

    @GetMapping("/image")
    public Object image(@RequestParam("msg") String message) {
        ImageResponse imageResp = openAiImageModel.call(new ImagePrompt(message));
        System.out.println(imageResp);
        // 图片URL
        String imageUrl = imageResp.getResult().getOutput().getUrl();
        return imageResp;
    }

    @GetMapping("/image/option")
    public Object imageOption(@RequestParam("msg") String message) {
        ImageResponse imageResponse = openAiImageModel.call(new ImagePrompt(message, OpenAiImageOptions.builder()
                .withQuality("hd") //高清图像
                .withN(1)  //生成1张图片
                .withHeight(1024) //生成的图片高度
                .withWidth(1024) //生成的图片宽度
                .build()));
        System.out.println(imageResponse);
        // 图片URL
        String imageUrl = imageResponse.getResult().getOutput().getUrl();

        return imageResponse.getResult().getOutput();
    }
}

文件存储工具

package com.demo.springai04texttospeechtts.util;

import java.io.*;

public class FileUtils {

    public static boolean saveFile(String fname, byte[] msg) {
        OutputStream fos = null;
        try{
            File file = new File(fname);
            File parent = file.getParentFile();
            boolean bool;
            if ((!parent.exists()) &&
                    (!parent.mkdirs())) {
                return false;
            }
            fos = new FileOutputStream(file);
            fos.write(msg);
            fos.flush();
            return true;
        }catch (FileNotFoundException e){
            return false;
        }catch (IOException e){
            e.printStackTrace();
            return false;
        }
        finally{
            if (fos != null) {
                try{
                    fos.close();
                }catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

六、多模态API(ChatModel)

官网API文档:Multimodality API :: Spring AI Reference

多模态是指模型同时理解和处理来自各种来源的信息的能力,包括文本、图像、音频和其他数据格式; 多模式大语言模型(LLM)特征使模型能够结合其他模态(如图像、音频或视频)来处理和生成文本; Spring AI 多模态API提供了所有必要的统一抽象和代码封装来支持多模式LLM

1、application.yml配置文件

spring:
  application:
    name: spring-ai-02-image
  ai:
    openai:
      api-key: ${OPENAI_API_KEY} # 换成你自己的api-key
      #如果是购买的转发地址,这边换成转发的OpenAI地址
      base-url: ${OPENAI_BASE_URL}  

2、测试类

package com.demo.springai05multimodel.controller;

import jakarta.annotation.Resource;
import org.springframework.ai.chat.messages.UserMessage;
import org.springframework.ai.chat.model.ChatModel;
import org.springframework.ai.chat.model.ChatResponse;
import org.springframework.ai.chat.prompt.Prompt;
import org.springframework.ai.model.Media;
import org.springframework.core.io.ClassPathResource;
import org.springframework.util.MimeTypeUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @description:
 * @author: zm
 */
@RestController
@RequestMapping("/ai")
public class MultiModelController {
    @Resource
    private ChatModel chatModel;

    @GetMapping("/multimodel")
    public String multimodel(String message, String imgUrl) {
        // 也可换成网络图片
        ClassPathResource classPathResource = new ClassPathResource("/花.jpeg");
        UserMessage userMessage = new UserMessage(message, new Media(MimeTypeUtils.IMAGE_JPEG, classPathResource));
        ChatResponse response = chatModel.call(new Prompt(userMessage));
        System.out.println(response
        );
        return response.getResult().getOutput().getContent();
    }
}
