JAVA调用ollama部署的离线deepseek

当我们下载好了离线的ollama和deepseek-R1模型的时候，如何对接到java代码中？如何实现关联上下文的会话？废话不多说，直接上代码：

注意：这里我的ollama部署到另一台机子的，ollama默认安装后只允许本机访问，所以我单独运行了个端口11433来转发ollama默认的11434，如果你们是本机部署的ollama就直接用11434端口+本机ip即可

import cn.hutool.json.JSONArray;
import cn.hutool.json.JSONObject;
import okhttp3.*;

import java.io.IOException;
