Spring boot集成milvus(spring ai)

news 来源：原创 2025/5/30 7:01:47

服务器部署Milvus

Run Milvus with Docker Compose (Linux)

milvus版本可在docker-compose.yml中进行image修改
在这里插入图片描述
启动后，docker查看启动成功

spring boot集成milvus

参考了这篇文章

Spring AI开发RAG示例，理解RAG执行原理

但集成过程中遇到了一系列问题，所以想着记录一下，省的以后再次集成遇到同样的问题看这一篇文章就行了

问题1 启动时报错，错误信息为 INTERNAL: Failed to frame message和This is supposed to be overridden by subclasses.

问题1解答

实际问题为（spring-ai-milvus-store）中（milvus-sdk-java）中的（protobuf-java）的版本问题
（protobuf-java）版本修改逻辑为图中的版本3.24.0 在这里插入图片描述

修改后的代码为

        <dependency><groupId>org.springframework.ai</groupId><artifactId>spring-ai-milvus-store</artifactId><version>${spring-ai.version}</version><exclusions><exclusion><groupId>com.google.protobuf</groupId><artifactId>protobuf-java</artifactId></exclusion></exclusions></dependency><dependency><groupId>com.google.protobuf</groupId><artifactId>protobuf-java</artifactId><version>3.24.0</version><scope>compile</scope></dependency>
