一、项目准备（最简依赖）

1. 创建 Spring Boot 项目

推荐版本：Spring Boot 3.2.x +JDK 版本：17+

2. pom.xml 核心依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.2.5</version>
        <relativePath/>
    </parent>

    <groupId>com.example</groupId>
    <artifactId>spring-ai-demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <properties>
        <java.version>17</java.version>
        <spring-ai.version>1.0.0-M1</spring-ai.version>
    </properties>

    <dependencies>
        <!-- Spring Web -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- Spring AI OpenAI 核心依赖 -->
        <dependency>
            <groupId>org.springframework.ai</groupId>
            <artifactId>spring-ai-openai-spring-boot-starter</artifactId>
        </dependency>
    </dependencies>

    <!-- Spring AI 仓库 -->
    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.ai</groupId>
                <artifactId>spring-ai-bom</artifactId>
                <version>${spring-ai.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
</project>

二、配置文件（application.yml）

这里以OpenAI为例，国内模型我在下面给你替换方案

spring:
  ai:
    openai:
      # OpenAI API Key
      api-key: sk-xxxxxxxxxxxxxxxxxxxxxxxx
      # 代理地址（国内必须加，否则无法访问）
      base-url: https://api.openai-proxy.com
      chat:
        options:
          # 模型名称
          model: gpt-3.5-turbo
          # 温度（0=严谨 1=创意）
          temperature: 0.7

三、核心代码（直接复制）

1. 启动类

package com.example.springaidemo;

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

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

2. AI 对话接口（Controller）

package com.example.springaidemo.controller;

import org.springframework.ai.chat.client.ChatClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class AiController {

    private final ChatClient chatClient;

    // 构造注入 ChatClient
    public AiController(ChatClient.Builder chatClientBuilder) {
        this.chatClient = chatClientBuilder.build();
    }

    /**
     * 简单AI对话接口
     * @param message 用户提问
     * @return AI回答
     */
    @GetMapping("/ai/chat")
    public String chat(@RequestParam String message) {
        return chatClient.prompt()
                .user(message)
                .call()
                .content();
    }
}

四、运行测试

启动项目后，浏览器访问：

http://localhost:8080/ai/chat?message=你好，介绍一下Spring AI
