二、yaml配置

java 复制代码

spring:
  application:
    name: spring_ollama_ai
  ai:
    ollama:
      base-url: http://localhost:11434
      timeout: 120s
      chat:
        options:
          model: iot-deepseek:latest
          keep_alive: 30m
          temperature: 0.7
          top-p: 0.9
          num-ctx: 4096

三、测试Controller

java 复制代码

package org.panda.controller;

import org.springframework.ai.ollama.OllamaChatModel;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;

@RestController
@RequestMapping("/chat")
public class ChatController {

    @Autowired
    private OllamaChatModel chatModel;


    @GetMapping("/stream")
    public Flux<String> chatStream(@RequestParam String message) {
        return chatModel.stream(message);
    }
}
