2、pom文件依赖 parent依赖

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

3、deepseek  api配置

deepseek:
  api-key: sk-xxxxxxxxxxx
  model: deepseek-r1
  base-url: https://xxx.xxxx.xxxx.xxxx.com/v1

4、代码

package com.yh.im.controller;

import io.github.pigmesh.ai.deepseek.core.DeepSeekClient;
import io.github.pigmesh.ai.deepseek.core.chat.ChatCompletionRequest;
import io.github.pigmesh.ai.deepseek.core.chat.ChatCompletionResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;

@RestController
public class DeepSeekController {

    @Autowired
    private DeepSeekClient deepSeekClient;

    @GetMapping(value = "/chat", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
    public Flux<ChatCompletionResponse> chat(String prompt) {
        return deepSeekClient.chatFluxCompletion(prompt);
    }

    @GetMapping(value = "/sync/chat")
    public ChatCompletionResponse syncChat(String prompt) {
        ChatCompletionRequest request = ChatCompletionRequest.builder()
                // 根据渠道模型名称动态修改这个参数
//                .model(deepSeekProperties.getModel())
                .addUserMessage(prompt).build();

        return deepSeekClient.chatCompletion(request).execute();
    }
}
