littlepdf 是一个基于数据+模板->html->pdf的小型框架,html渲染模板用户可自行配置,内置thymeleaf,freemarker,word三种实现,实现 IRender接口即可
使用方式参见:little-pdf-springboot-sample,html渲染成pdf基于itext5+flying-saucer(css1.0,css2.0 支持)
基础模板:
html+css ->pdf
word(docx)->docx->pdf
word ->pdf 依赖jodconverter ->apache openoffice或者libreoffice
适合简单pdf生成,如各种电子合同(租房,网贷,借款等),要求严苛的pdf生成并不适合,渲染pdf过程中,支持多种资源加载方式:
- 网络
- classpath
- 文件系统具体参见:TemplateLoaderUtil
