可选择ollama或者openai其一进行大模型配置

server:tomcat:max-swallow-size: -1     # 禁用Tomcat的请求大小限制（或设为足够大的值，如100MB）
spring:application:name: heima-aiservlet:multipart:max-file-size: 50MB    # 单个文件限制max-request-size: 100MB # 单次请求总限制# AI服务配置（多引擎支持）ai:# Ollama配置（本地大模型引擎）ollama:base-url: http://localhost:11434  # Ollama服务地址（默认端口11434）chat:model: deepseek-r1:7b  # 使用的模型名称（7B参数的本地模型）# 阿里云OpenAI兼容模式配置openai:base-url: https://dashscope.aliyuncs.com/compatible-mode  # 阿里云兼容API端点api-key: ${OPENAI_API_KEY}  # 从环境变量读取API密钥（安全建议）chat:options:model: qwen-max-latest  # 通义千问最新版本模型# 日志级别配置
logging:level:org.springframework.ai: debug  # 打印Spring AI框架调试日志com.itheima.ai: debug         # 打印业务代码调试日志

特别注意：在SpringAI的当前版本（1.0.0-m6)中，qwen-omni与SpringAI中的OpenAI模块的兼容性有问题，目前仅支持文本和图片两种模态。音频会有数据格式错误问题，视频完全不支持。音频识别中的数据格式，阿里云百炼的qwen-omni模型要求的参数格式为data:;base64,${media-data}，而OpenAI是直接{media-data}。

目前的解决方案有两种：

  • 一是使用spring-ai-alibaba来替代。

  • 二是重写OpenAIModel的实现。

接下来，我们就用重写OpenAiModel的方式，来实现多模态效果。

自实现 AlibabaOpenAiChatModel (仿照OpenAiModel来写)

主要修改了buildGeneration、fromAudioData方法

ChatController对话类

会话id由前端进行生成并传输过来，当然也可后端自己生成并且存入数据库，不过这里由于是简单的实现，由本地Map实现会话及信息的存储

根据前端是否传过来files来判断是否为多模态调用，有文件则走multiModalChat方法

import lombok.RequiredArgsConstructor;
import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.model.Media;
import org.springframework.util.MimeType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import reactor.core.publisher.Flux;
import java.util.List;
import java.util.Objects;
import static org.springframework.ai.chat.client.advisor.AbstractChatMemoryAdvisor.CHAT_MEMORY_CONVERSATION_ID_KEY;@RequiredArgsConstructor // 构造方式自动注入
@RestController
@RequestMapping("/ai")
public class ChatController {private final ChatClient chatClient;private final ChatHistoryRepository chatHistoryRepository;@RequestMapping(value = "/chat", produces = "text/html;charset=utf-8")public Flux<String> chat(@RequestParam("prompt") String prompt,@RequestParam("chatId") String chatId,@RequestParam(value = "files", required = false) List<MultipartFile> files) {// 1.保存会话idchatHistoryRepository.save("chat", chatId);// 2.请求模型if (files == null || files.isEmpty()) {// 没有附件，纯文本聊天return textChat(prompt, chatId);} else {// 有附件，多模态聊天return multiModalChat(prompt, chatId, files);}}private Flux<String> multiModalChat(String prompt, String chatId, List<MultipartFile> files) {// 1.遍历解析多媒体，转为Media对象List<Media> medias = files.stream().map(file -> new Media(MimeType.valueOf(Objects.requireNonNull(file.getContentType())),file.getResource())).toList();// 2.请求模型return chatClient.prompt().user(p -> p.text(prompt).media(medias.toArray(Media[]::new))).advisors(a -> a.param(CHAT_MEMORY_CONVERSATION_ID_KEY, chatId)).stream().content();}private Flux<String> textChat(String prompt, String chatId) {return chatClient.prompt().user(prompt).advisors(a -> a.param(CHAT_MEMORY_CONVERSATION_ID_KEY, chatId)).stream().content();}
}

ChatHistoryController会话历史类

实现本地Map存储chat类型与所有会话历史的对应关系，找到会话后就可用根据聊天记忆ChatMemory找到聊天历史

import lombok.RequiredArgsConstructor;
import org.springframework.ai.chat.memory.ChatMemory;
import org.springframework.ai.chat.messages.Message;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;@RequiredArgsConstructor
@RestController
@RequestMapping("/ai/history")
public class ChatHistoryController {private final ChatHistoryRepository chatHistoryRepository;private final ChatMemory chatMemory;@GetMapping("/{type}")public List<String> getChatIds(@PathVariable("type") String type) {return chatHistoryRepository.getChatIds(type);}@GetMapping("/{type}/{chatId}")public List<MessageVO> getChatHistory(@PathVariable("type") String type, @PathVariable("chatId") String chatId) {List<Message> messages = chatMemory.get(chatId, Integer.MAX_VALUE);if(messages == null) {return List.of();}// 转换成VOreturn messages.stream().map(MessageVO::new).toList();}
}

ChatHistoryRepository 会话历史业务接口 

import java.util.List;public interface ChatHistoryRepository {/*** 保存会话记录* @param type 业务类型，如：chat、service、pdf* @param chatId 会话ID*/void save(String type, String chatId);/*** 获取会话ID列表* @param type 业务类型，如：chat、service、pdf* @return 会话ID列表*/List<String> getChatIds(String type);
}

InMemoryChatHistoryRepository实现类

@Slf4j
@Component
@RequiredArgsConstructor
public class InMemoryChatHistoryRepository implements ChatHistoryRepository {// 会话chatId存储Mapprivate Map<String, List<String>> chatHistory;private final ChatMemory chatMemory;// 保存会话ID@Overridepublic void save(String type, String chatId) {/*if (!chatHistory.containsKey(type)) {chatHistory.put(type, new ArrayList<>());}List<String> chatIds = chatHistory.get(type);*/List<String> chatIds = chatHistory.computeIfAbsent(type, k -> new ArrayList<>());if (chatIds.contains(chatId)) {return;}chatIds.add(chatId);}// 获取所有会话id@Overridepublic List<String> getChatIds(String type) {/*List<String> chatIds = chatHistory.get(type);return chatIds == null ? List.of() : chatIds;*/return chatHistory.getOrDefault(type, List.of());}}

MessageVO返回实体类 

根据ChatMemory中存储的Message可知有四种类型，则根据Message来示例VO对象

USER("user"),
ASSISTANT("assistant"),
SYSTEM("system"),
TOOL("tool");

import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.ai.chat.messages.Message;@NoArgsConstructor
@Data
public class MessageVO {private String role;private String content;public MessageVO(Message message) {switch (message.getMessageType()) {case USER:role = "user";break;case ASSISTANT:role = "assistant";break;default:role = "";break;}this.content = message.getText();}
}

3.2 前端代码

可以根据这些代码与接口让Cursor生成一个仿deepseek页面即可实现，或者根据下列Vue项目代码修改实现(实现效果中的代码)
