1.增加依賴
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf</artifactId>
<version>9.1.5</version>
</dependency>
2.java實現
/**
* html轉pdf
*
* @throws Exception
*/
public static void testHtml2Pdf(String htmlfilePath) {
String str = "";
try {
String tempStr = "";
FileInputStream is = new FileInputStream(htmlfilePath);//讀取模塊文件
BufferedReader br = new BufferedReader(new InputStreamReader(is));
while ((tempStr = br.readLine()) != null)
str = str + tempStr;
is.close();
} catch (IOException e) {
e.printStackTrace();
}
try {
//指定PDF的存放路徑
OutputStream os = new FileOutputStream("C:\\Users\\Administrator\\Desktop\\in.pdf");
//OutputStream os = response.getOutputStream();
ITextRenderer renderer = new ITextRenderer();
ITextFontResolver fontResolver = renderer.getFontResolver();
//指定字體。爲了支持中文字體
if ("linux".equals(getCurrentOperatingSystem())) {
fontResolver.addFont("/usr/share/fonts/chiness/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
} else {
fontResolver.addFont("C:/WINDOWS/Fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
}
renderer.setDocumentFromString(str);
// 解決圖片的相對路徑問題
//renderer.getSharedContext().setBaseURL("src/main/resources/file");
renderer.layout();
renderer.createPDF(os);
renderer.finishPDF();
os.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public static String getCurrentOperatingSystem() {
String os = System.getProperty("os.name").toLowerCase();
System.out.println("---------當前操作系統是-----------" + os);
return os;
}
