Springboot結(jié)合thymeleaf模板生成pdf文件的代碼示例
更新時間：2026年07月07日 09:40:42 作者：愛碼猿
Thymeleaf作為SpringBoot官方推薦的模板引擎,采用自然模板設(shè)計理念,其三層處理管道實現(xiàn)了HTML5的優(yōu)雅處理,這篇文章主要介紹了Springboot結(jié)合thymeleaf模板生成pdf文件的相關(guān)資料,需要的朋友可以參考下
1. 導(dǎo)入依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>com.github.librepdf</groupId>
<artifactId>openpdf</artifactId>
<version>1.3.30</version>
</dependency>
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf-openpdf</artifactId>
<version>9.4.0</version>
</dependency>
2. 創(chuàng)建Html模板
在resource/template下創(chuàng)建模板文件，需要注意的是樣式必須寫在style標(biāo)簽內(nèi)，不能寫在標(biāo)簽內(nèi)部，否則無效。
