Java Poi-tl根據(jù)模板導(dǎo)出Word文件
更新時(shí)間：2025年03月13日 10:10:28 作者：桃花面包
這篇文章主要為大家詳細(xì)介紹了Java如何使用Poi-tl根據(jù)模板實(shí)現(xiàn)導(dǎo)出Word文件,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下
Poi-tl官網(wǎng)：Poi-tl Documentation
最近又碰上了導(dǎo)出，真的服了，還是低代碼的導(dǎo)出，其中過(guò)程的曲折真的是一言難盡..........平臺(tái)各種適配，依賴沖突，真的是崩潰.......
簡(jiǎn)單說(shuō)一下為什么使用Poi-tl，最開始想用的是poi實(shí)現(xiàn)，但是結(jié)果就是poi不好控制圖片的位置，因?yàn)閳D片插入之后是“浮于文字上方”，單純的插入圖片會(huì)占行數(shù)，為了方便控制格式后續(xù)就采用了poi-tl但是他同樣也不支持插入圖片之后將圖片設(shè)置為“浮于文字上方”，也是找了一些博客參考，最終實(shí)現(xiàn)了想要的效果
參考博客：poi-tl導(dǎo)出word實(shí)現(xiàn)圖片環(huán)繞方式為浮于在文字上方辦法
老樣子上效果圖：
實(shí)現(xiàn)步驟
1.準(zhǔn)備模板
2.添加依賴
