yaml配置文件：

spring:
    ai:
        openai:
            base-url: https://api.deepseek.com  # DeepSeek的OpenAI式端点
            api-key: sk-a26bd8370bf349f3a47313685917fe4d
            chat.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
    @Bean
    public 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);
    }
}
