一、先申请key

1.1 登录阿里云官网并搜索模型服务灵积，开通key

1.2 点击上图中的控制台并进入

1.3 创建key

二、导入依赖坐标

2.1 导入以下俩个坐标

<!--阿里巴巴大模型--> <!-- https://mvnrepository.com/artifact/com.alibaba/dashscope-sdk-java --> <dependency> <groupId>com.alibaba</groupId> <artifactId>dashscope-sdk-java</artifactId> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-simple</artifactId> </exclusion> </exclusions> <version>2.8.3</version> </dependency>

<dependency> <groupId>com.squareup.okhttp3</groupId> <artifactId>okhttp</artifactId> <version>4.10.0</version> </dependency>

2.2 编写Controller层 

这里controller层并未将前端的请求数据传入给api中的参数，有需求的可以自己加一下，这里就使用浏览器测试一下看是否返回数据即可

​import com.alibaba.dashscope.aigc.generation.GenerationResult;import com.alibaba.dashscope.exception.InputRequiredException;import com.alibaba.dashscope.exception.NoApiKeyException;import com.ruoyi.aliyunchat.service.ChatService;import com.ruoyi.common.annotation.Anonymous;import com.ruoyi.pojo.Result;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@Slf4j@RestController@Anonymouspublic class ChatController { @Autowired private ChatService chatService; @RequestMapping("/chat") public Result chatAi() throws NoApiKeyException, InputRequiredException { GenerationResult generationResult = chatService.chatAi(); return Result.success(generationResult); }}​

 2.3 Servic层及实现类

接口

import com.alibaba.dashscope.aigc.generation.GenerationResult;import com.alibaba.dashscope.exception.InputRequiredException;import com.alibaba.dashscope.exception.NoApiKeyException;public interface ChatService { GenerationResult chatAi() throws NoApiKeyException, InputRequiredException;}

实现类

import com.alibaba.dashscope.aigc.generation.GenerationResult;import com.alibaba.dashscope.exception.InputRequiredException;import com.alibaba.dashscope.exception.NoApiKeyException;import com.ruoyi.aliyunchat.aliqianwen.QianWenChat;import com.ruoyi.aliyunchat.service.ChatService;import org.springframework.stereotype.Service;@Servicepublic class ChatServiceImpl implements ChatService { @Override public GenerationResult chatAi() throws NoApiKeyException, InputRequiredException { return QianWenChat.callWithMessage(); }}

接着就是官网上的Demo了，我们这里封装一下

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 lombok.extern.slf4j.Slf4j;@Slf4jpublic class QianWenChat { public static GenerationResult callWithMessage() throws NoApiKeyException, ApiException, InputRequiredException { Constants.apiKey="你的key"; Generation gen = new Generation(); MessageManager msgManager = new MessageManager(10); Message systemMsg = Message.builder().role(Role.SYSTEM.getValue()).content("You are a helpful assistant.").build(); Message userMsg = Message.builder().role(Role.USER.getValue()).content("请问杭州阿里巴巴工作环境咋样？").build(); msgManager.add(systemMsg); msgManager.add(userMsg); QwenParam param = QwenParam.builder().model(Generation.Models.QWEN_TURBO).messages(msgManager.get()) .resultFormat(QwenParam.ResultFormat.MESSAGE) .topP(0.8) .enableSearch(true) .build(); GenerationResult result = gen.call(param); log.info("千问api回答的话语为：{}",result); System.out.println(result); return result; }}

三、测试

3.1 在浏览器中输入后端本地，并请求接口，响应如下
