我需要将HTML页面的一部分和java中的一部分数据转换为单个PDF进行生产。如何实现？

例如：我有一个包含图像和数据库中的一些数据的页面。从这两个可用数据中，我想创建一个PDF文档。最佳解决方案是什么

您可以尝试从视差生成jsPDF，生成PDF非常简单

您可以尝试使用iText 7，我们可以在其中定义页眉、页脚、图像、css文件等选项

下面是Itext中提供的示例代码

谢谢。但我正在用Java搜索解决方案。我过去使用过com.itextpdf。@Wesleydekeirsmaker谢谢。我在分析它。这实际上是在要求我们推荐使用库，因为该功能不是核心Java类的一部分。这类问题与堆栈溢出无关。
