yaml配置文件：

spring:ai:openai:base-url: https://api.deepseek.com  # DeepSeek的OpenAI式端点api-key: sk-a26bd8370bf349f3a47313685917fe4dchat.options:model: deepseek-chat  # 指定DeepSeek的模型名称

添加配置类：

package com.xp.ai.config;import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.openai.OpenAiChatModel;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class CommonConfiguration {// 注意参数中的model就是使用的模型，这里用了Ollama，也可以选择OpenAIChatModel@Beanpublic ChatClient chatClient(OpenAiChatModel model) {return ChatClient.builder(model) // 创建ChatClient工厂.build(); // 构建ChatClient实例}
}

添加service层：

package com.xp.ai.service;import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.chat.model.ChatResponse;
import org.springframework.stereotype.Service;
import reactor.core.publisher.Flux;@Service
public class AiChatService {private final ChatClient chatClient;public AiChatService(ChatClient chatClient) {this.chatClient = chatClient;}// 流式响应方法public Flux<String> streamChat(String message) {return chatClient.prompt().user(message).stream().content();}}

controller：

package com.xp.ai.controller;import com.xp.ai.service.AiChatService;
import org.springframework.http.MediaType;
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;@RestController
@RequestMapping("/api/chat")
public class ChatController {private final AiChatService aiChatService;public ChatController(AiChatService aiChatService) {this.aiChatService = aiChatService;}@GetMapping(value = "/stream", produces = MediaType.TEXT_EVENT_STREAM_VALUE)public Flux<String> streamChat(@RequestParam String message) {return aiChatService.streamChat(message);}
}
