通過html生成pdf捉撮，可使用睿印 工具包栋艳，睿印java工具包是集成openhtmltopdf抓谴，pdfbox的開源工具包钧椰，集成了thymeleaf 動(dòng)態(tài)腳本蛛壳，并可自動(dòng)加載字體杏瞻，默認(rèn)支持中文顯示。
- 首先新建java maven項(xiàng)目衙荐，引入jar包
<dependency>
<groupId>ink.rayin</groupId>
<artifactId>rayin-htmladapter-openhtmltopdf</artifactId>
<version>1.0.8</version>
</dependency>
- 新建html捞挥，保存至test/resources下，命名為element1.html

- 項(xiàng)目test中新建測試類
@Slf4j
public class PDFGeneratorOpenhtmltopdfTest {
static PdfGenerator pdfGenerator;
static {
try {
pdfGenerator = new PdfBoxGenerator();
pdfGenerator.init();
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void markbooksTest() throws Exception {
log.info("markbooksTest start time：" + new Timestamp(System.currentTimeMillis()));
String outputFileClass = ResourceUtil.getResourceAbsolutePathByClassPath("");
// 生成pdf路徑
// generate pdf path
String outputFile = new File(outputFileClass)
.getParentFile().getParent()
+ "/tmp/"
+ "markbooks_"+System.currentTimeMillis() + ".pdf";
//數(shù)據(jù)參數(shù)可以為空
pdfGenerator.generatePdfFileByHtmlAndData(ResourceUtil.getResourceAbsolutePathByClassPath("element1.html"),null,outputFile);
log.info("markbooksTest end time：" + new Timestamp(System.currentTimeMillis()));
}
}

生成PDF如下
帶書簽的pdf
至此大功告成赫模！
pdfbox讀取pdf書簽
生成的pdf標(biāo)簽也可以通過pdfbox來讀取树肃。
@Test
public void bookmarksTest() throws IOException {
PDDocument pdfWithBookmarks = PDDocument.load(ResourceUtil.getResourceAsStream("bookmark.pdf"));
PDDocumentOutline pdo = pdfWithBookmarks.getDocumentCatalog().getDocumentOutline();
printBookmark(pdfWithBookmarks, pdo, "");
pdfWithBookmarks.close();
}
//遞歸獲取書簽
public void printBookmark(PDDocument pd, PDOutlineNode bookmark, String indentation) throws IOException{
PDOutlineItem current = bookmark.getFirstChild();
while (current != null) {
PDPage currentPage = current.findDestinationPage(pd);
// 獲取書簽對(duì)應(yīng)對(duì)的頁碼
Integer pageNumber = pd.getDocumentCatalog().getPages().indexOf(currentPage) + 1;
System.out.println(indentation + current.getTitle() + "----------------" + pageNumber);
printBookmark(pd, current, indentation + " ");
current = current.getNextSibling();
}
}
