🔥Java 调用 Deepseek-R1.1.5b 大模型超详细教程来啦！
宝子们，今天给大家分享如何用 Java 调用 Deepseek-R1.1.5b 大模型，真的有被惊艳到🤩，跟着步骤来，有手就会！快来抄作业📝

一、部署本地 DeepSeek 模型（核心步骤）
创建自己专属DeepSeek实现大模型 全过程!!!（超详细教程）-优快云博客
二、Java本地测试代码
public class OllamaDemo {
private static final String API_URL = "http://localhost:11435/api/generate";
public static final String askDeepSeek(String prompt) {
JSONObject param = new JSONObject();
param.set("model", "deepseek-r1:1.5b")
.set("prompt", prompt)
.set("stream", false)
.set("temperature", 0.7);
return HttpRequest.post(API_URL)
.body(param.toString())
.timeout(30000)
.execute()
.body();
}
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入你的问题(输入退出停止运行):");
String question = scanner.nextLine();
System.out.println(askDeepSeek(question));
}
}三、Java实现跨域代码
2.1 Controller类
public JsonResult getQuestion(String question) {
return JsonResult.ok(questionService.getAnswer(question));
}2.2 Service接口
String getAnswer(String question);2.3 Service类
private static final String API_URL = "http://localhost:11435/api/generate";
public String getAnswer(String question) {
JSONObject param = new JSONObject();
param.set("model", "deepseek-r1:1.5b")
.set("prompt", prompt)
.set("stream", false)
.set("temperature", 0.7);
String responseBody = HttpRequest.post(API_URL)
.body(param.toString())
.timeout(30000)
.execute()
.body();
JSONObject responseJson = new JSONObject(responseBody);
return responseJson.getStr("response");
