html 轉 pdf
第一步 引用需求包Itext和core-renderer
<dependency> <groupId>com.lowagie</groupId> <artifactId>itext</artifactId> <version>2.0.8</version> </dependency> <dependency> <groupId>org.xhtmlrenderer</groupId> <artifactId>core-renderer</artifactId> <version>R8</version> </dependency>
第二步 下載字型檔案 simsun.ttc
第三步 準備html檔案
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title @page {size: 310mm 200mm;}
@page設定列印頁面大小 310毫米寬，200毫米高
body {font-family:SimSun}
設定字型
準備編寫工具類 HtMLToPdf
