Itextpdf添加页眉页脚页码

Love The Way You Lie 2023-02-17 02:51 138阅读 0赞

项目需要样式比较复杂，刚开始因为时间比较紧所以采用了Itextpdf插件代码生成pdf ,实话说过程十分繁琐，因为pdf文件样式比较多，表格也比较多，各种的表格，还有就是页眉页脚页码都要自己找页面位置坐标但是又不能像html那样方便更改查看样式，只能改一点导出来看看合适不，然后再改再导出来看。
私下调研了很多，现在罗列一下我所用到的一些样式处理，希望可以帮助需要做这个功能的朋友少踩坑，少尝试，直接出完美pdf报告。

  2. 首页在这里插入图片描述
    封面右上角那个图片可以换成logo，我做的大概是这样的一个样子，上代码

接下来是页眉页脚事件的代码PDFBUilder
因为页眉页脚都是带格式的，所以需要一点一点拼接起来，页眉中需要添加logo图片，位置是通过代码中的x，y坐标指定的
