application.properties 配置文件

spring.application.name=deepseek-study
spring.ai.ollama.base-url=http://127.0.0.1:11434
spring.ai.ollama.chat.options.model=deepseek-r1:32b

说明：列出最核心的两个配置，更多配置项见 spring-ai-ollama 文档

• spring.ai.ollama.base-url：ollama 服务的基础 url
• spring.ai.ollama.chat.options.model：指定使用的 ollama 服务

controller:

package cn.aileading.deepseek_study.web;

import jakarta.annotation.Resource;
import org.springframework.ai.ollama.OllamaChatModel;
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 java.util.Map;

@RestController
@RequestMapping("/")
public class Controller {
    @Resource
    private OllamaChatModel chatModel;

    @GetMapping("/ai/generate")
    public Map<String,String> generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) {
        return Map.of("generation", this.chatModel.call(message));
    }
}

启动器：

package cn.aileading.deepseek_study;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DeepseekStudyApplication {
	public static void main(String[] args) {
		SpringApplication.run(DeepseekStudyApplication.class, args);
	}
}

启动应用

启动应用，浏览器访问，http://127.0.0.1:8080/ai/generate?message=0.8和0.11谁大 ，查看输出即可
