# JRXML RAG 项目
|
||||
|
||||
基于 RAG（Retrieval-Augmented Generation）的 JasperReports JRXML 模板智能问答系统，构建JRXML自定义agent的前置工作。
|
||||
基于 RAG 的 JasperReports JRXML 模板 + Markdown 文档智能检索系统，作为构建 JRXML 自定义 Agent 的前置工作。
|
||||
|
||||
## 项目简介
|
||||
|
||||
本项目将 JasperReports 的 JRXML 模板文件进行语义分块、向量化，并存入 Chroma 向量数据库，实现通过自然语言查询来检索和理解报表模板的结构、配置和逻辑。
|
||||
支持 JRXML 模板和 Markdown 文档的语义分块、向量化、Chroma 持久化存储，以及自然语言查询。

|
||||
```bash
|
||||
# 1. 收集 JRXML 文件
|
||||
python collect_jrxml.py
|
||||
|
||||
# 2. 语义分块
|
||||
python jrxml_banch_chunker.py ./jrxml_source --output ./jrxml_chunker_output
|
||||
# 2. 统一分块 (JRXML + Markdown)
|
||||

||||
python embed_chunks.py
|
||||
|
||||
# 5. 导入 Chroma 数据库

# 5. 导入 Chroma
|
||||
python import_to_chroma.py
|
||||
|
||||
# 6. 开始查询

### 快速查询
|
||||
### 增量更新
|
||||
|
||||
新增或修改部分文件时，无需重新处理全部数据：
|
||||
|
||||
```bash
|
||||
# 分块新文件
|
||||
python batch_chunker.py ./new_files --output ./jrxml_chunker_output/new_batch
|
||||
|
||||
# 增量向量化 (只处理新 chunks)
|
||||
python embed_chunks.py ./jrxml_chunker_output/new_batch/all_chunks.json --incremental
|
||||
|
||||
# 增量导入 (不删除已有数据)
|
||||
python import_to_chroma.py --incremental
