Spring AI快速入门-基于DeepSeek&智谱实现聊天应用

上一篇文章分享了IntelliJ IDEA集成主流 AI 编程助手及特性介绍今天这篇文章我们来分享Spring AI快速入门-SpringAI 基于DeepSeek&智谱实现聊天应用。

文章最后可以加入免费的Java技术栈沟通社群，一起探讨Java/你的产品如何与AI结合，请按照要求加入。在群中可以聊开发、系统设计、架构、行业趋势、AI等等话题

完整代码在文章最后，如果觉得本篇文章对你有用，记得点赞、关注、收藏哦。你的支持是我持续更新的动力!

AI专栏软件环境

IntelliJ IDEA2024.3.2.2
Spring AI 1.0.0-SNAPSHOT
Spring Boot 3.4.2
Spring 6.2.2
智谱AI大模型
DeepSeek
JDK 17.0.12

我们先看本篇文章对应的项目结构，请看下图

1 Spring AI

Spring AI是一个用于AI项目的应用框架。它的目标是将Spring生态系统设计原则（如可移植性和模块化设计）应用于AI领域，并促进像开发Spring企业应用一样构建AI领域应用程序。

Spring AI能做什么？

支持目前主流大语言模型平台，例如 OpenAI、Microsoft、Amazon、Google、智普和 Huggingface
支持阻塞与流式的文本对话
支持图像生成(当前仅限OpenAI的dall-e-*模型和SD)
支持嵌入模型
支持LLM生成的内容转为POJO
支持主流的向量数据库或平台：Azure Vector Search, Chroma, Milvus, Neo4j, PostgreSQL/PGVector, PineCone, Qdrant, Redis 和 Weaviate
支持函数调用
支持自动装配和启动器（与Spring Boot完美集成）
提供用于数据处理工程的ETL框架
