# RAG-demo
Java+Milvus,Build an RAG application
## Environment version
milvus 2.5.5+jdk 17+aliyun-bailian text-embedding-v3
## brief introduction
This project uses ten sets of simulated data derived from the vector database of the Chinese Criminal Law as the vector data for the simulation.
This example demonstrates how to build a vector retrieval system for legal provisions using Milvus. Through the vectorization representation of text, it enables fast retrieval of similar legal provisions. The system will return the most relevant criminal law provisions based on the user's input question.
## Application configuration
##### milvus connect
``MilvusServiceClient client = new MilvusServiceClient(
                ConnectParam.newBuilder().withHost("localhost").withPort(19530).build());``
##### Mechanical model configuration
``String qwen_api_key = System.getenv("DASHSCOPE_API_KEY");``  
``private static final String API_URL = "https://dashscope.aliyuncs.com/compatible-mode/v1/embeddings";``  
``private final String API_KEY = qwen_api_key; // ← Replace with your actual API Key``
## Quick start
#### Start the Milvus service
recommend docker 
Please start the [Milvus service](https://milvus.io/docs/zh/prerequisite-docker.md) based on the environment of this machine.
#### run program
``
javac -cp ".:milvus-xxx-xxx-2.x.x.jar" xxx.java
``  
``
java -cp ".:milvus-xxx-xxx-2.x.x.jar" xxx
``
## Example output
