1、效果截图：

 2、代码部分：

application.properties

server.port=8080deepseek.api.token=sk-d34e929e887b4881813395241df2f745
deepseek.api.url=https://api.deepseek.com/chat/completions

 controller部分 请求参数可以缩短，写成实体类形式

3、依赖

<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.83</version></dependency>

controller可以简化这样的

@PostMapping("/deepSeek")public String callDeepSeek(@RequestBody String question) {// 创建消息列表List<Map<String, Object>> messages = new ArrayList<>();// 添加系统消息Map<String, Object> systemMessage = new HashMap<>();systemMessage.put("role", "system");systemMessage.put("content", "You are a helpful assistant");messages.add(systemMessage);// 添加用户消息Map<String, Object> userMessage = new HashMap<>();userMessage.put("role", "user");userMessage.put("content", question);messages.add(userMessage);// 创建请求 MapMap<String, Object> requestMap = new HashMap<>();requestMap.put("model", "deepseek-chat");requestMap.put("messages", messages);requestMap.put("stream", false);// 将 requestMap 转换为 JSON 字符串ObjectMapper objectMapper = new ObjectMapper();String requestBody = null;try {requestBody = objectMapper.writeValueAsString(requestMap);} catch (JsonProcessingException e) {throw new RuntimeException(e);}HttpHeaders headers = new HttpHeaders();headers.set("Authorization", "Bearer " + apiToken);headers.set("Content-Type", "application/json");HttpEntity<String> entity = new HttpEntity<>(requestBody, headers);ResponseEntity<String> response = restTemplate.exchange(apiUrl, HttpMethod.POST, entity, String.class);// 解析响应 JSONJSONObject jsonResponse = JSONObject.parseObject(response.getBody());String generatedText = jsonResponse.getJSONArray("choices").getJSONObject(0).getJSONObject("message").getString("content");return generatedText;}
