如果不想从零开始，可直接克隆我已经完成的源码：

gitclonehttps://github.com/amuguelove/eric-spring-ai-rag-demo

使用Spring Cli

#MacOS按照spring-cli工具
brewtapspring-cli-projects/spring-cli
brewinstallspring-cli

springbootnew--fromai--nameeric-spring-ai-rag-demo

使用Spring Initializr

这里使用IDEA创建，也可使用网页版：https://start.spring.io/，具体步骤查看下图：

OpenAI 凭证配置

需要替换成自己的OpenAI API key和代理URL，以下只是样例数据。

exportOPENAI_API_KEY=sk-1234567890abcdef1234567890abcdef
exportOPENAI_BASE_URL=https://api.openai.com/

Spring AI 项目配置

spring:
application:
name:spring-ai-rag-demo

datasource:
url:jdbc:postgresql://localhost:5432/postgres
username:postgres
password:postgres

ai:
openai:
api-key{OPENAI_API_KEY}
#Note：OpenAiApiwillsplice："/v1/chat/completions"
base-url{OPENAI_BASE_URL}

项目启动

./gradlwbootRun

验证OpenAI是否联通

GEThttp://localhost:8080/ai/generate
{
"question":"Tellmeajoke",
