服务:Spring Boot 3.2 + docx4j 8.3.9,POST /api/v3/server_office_file/file/parse
接受 .docx,返回 HTML(公式 → LaTeX,图片 → RustFS 外链)
公式支持三类来源:
- OMML(Word 2007+ 公式) → Python omml_mathml2latex
- MathType OLE 对象 → Ruby mathtype2mathml → MathML → LaTeX
- Word EQ 域(老教辅主力) → EqToLatexUtil(本次新增)
本次改动:
1. 新增 java-svc/.../core/EqToLatexUtil.java:
移植自 jby backend-services office-core,EQ 语法 → LaTeX
(\f→\dfrac、\r→\sqrt、\i→\int/\sum/\prod、\s→^{}/_{}、\b→\left\right、
\a→array、\x→\boxed/\overline、\o\al 堆叠、圈码、化学符号、极限、连等式)
品牌标记 JBYU* → WPU*,与采集端一致
2. CtoMathFinder:接上 EQ 分支(原为 not-ported 桩),域代码经
EqToLatexUtil.convert 转 LaTeX 写入 eqLatexMap(WPEQNUM 占位符)
3. WordParseUtil.dealPlaceholder:EQ 的 LaTeX 同样加 \( \) 包裹
(原先因 WPEQNUM 例外不加包裹,前端/MathJax 不渲染)
修前症状:教辅 Word 里分式/方程组/上下标整段丢失(如 {−1/3, 1} 变成 {-,1})
修后实测:46 份教辅 2908 处 EQ 域全部还原,公式总数 2954 处、零未包裹残留
安全:application.yml(含 RustFS 密钥)不入库,提供 application.yml.example;
OssService 的 @Value 默认密钥已清空
