import org.springframework.web.bind.annotation.RequestMapping;

 **/
@RestController
@RequestMapping("/hello")
public class HelloController {

    @Resource(name = "qwenChatClient")
    private ChatClient qwenChatClient;

    @Resource(name = "deepSeekChatClient")
    private ChatClient deepSeekChatClient;

    /**
     * 调用 qwen 模型
     * @param message
     * @return
     */
    @GetMapping("/qwen")
    public String qwen(@RequestParam(name = "message", defaultValue = "你是谁？") String message) {
        return qwenChatClient.prompt()
                .user(message)
                .call()
                .content();
    }

    /**
     * 调用 deepseek 模型
     * @param message
     * @return
     */
    @GetMapping("/deepSeek")
    public String deepSeek(@RequestParam(name = "message", defaultValue = "你是谁？") String message) {
        return deepSeekChatClient.prompt()

}

启动类

package com.junjiu.spring.ai.alibaba.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.event.ApplicationReadyEvent;
import org.springframework.context.ApplicationListener;

    }

    public ApplicationListener<ApplicationReadyEvent> readyEventApplicationListener(Environment env) {
        return event -> {
            System.out.println("\n🎉========================================🎉");
            System.out.println("✅ Application is ready!");
