这篇文章主要为大家介绍了Java调用Deepseek-R1.1.5b大模型的超详细教程并附上了代码,文中的教程讲解详细,有需要的小伙伴可以参考一下

一、部署本地 DeepSeek 模型（核心步骤）

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

3.1 Controller类

public JsonResult getQuestion(String question) {
        return JsonResult.ok(questionService.getAnswer(question));
    }

3.2 Service接口

String getAnswer(String question);

3.3 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");
    }
