Java Html轉PDF

1. 本方案依賴第三方庫支持openhtmltopdf
2. 在pom.xml裏添加maven依賴

	<properties>
		<openhtml.version>0.0.1-RC17</openhtml.version>
	</properties>
	<dependency>
		<groupId>com.openhtmltopdf</groupId>
		<artifactId>openhtmltopdf-pdfbox</artifactId>
		<version>${openhtml.version}</version>
	</dependency>
	
	<dependency>
		<groupId>com.openhtmltopdf</groupId>
		<artifactId>openhtmltopdf-java2d</artifactId>
		<version>${openhtml.version}</version>
	</dependency>
	
	<dependency>
		<groupId>com.openhtmltopdf</groupId>
		<artifactId>openhtmltopdf-rtl-support</artifactId>
		<version>${openhtml.version}</version>
	</dependency>
	
	<dependency>
		<groupId>com.openhtmltopdf</groupId>
		<artifactId>openhtmltopdf-jsoup-dom-converter</artifactId>
		<version>${openhtml.version}</version>
	</dependency>
	
	<dependency>

	<dependency>

		<version>${openhtml.version}</version>
	</dependency>
	
	<dependency>
		<groupId>com.openhtmltopdf</groupId>
		<artifactId>openhtmltopdf-svg-support</artifactId>
		<version>${openhtml.version}</version>
	</dependency>
	
	<dependency>
		<groupId>com.openhtmltopdf</groupId>
		<artifactId>openhtmltopdf-mathml-support</artifactId>
		<version>${openhtml.version}</version>
	</dependency>

3. 處理中文的時候，需要自己加字體，否則中文會亂碼。中文亂碼處理參考
4. 測試代碼

	public static void main(String[] args) throws Exception {
		OutputStream os = new FileOutputStream(
				"F:/logs/template.pdf");
		PdfRendererBuilder builder = new PdfRendererBuilder();
		builder.withHtmlContent(new String("html語句"), null);
		builder.useFont(new FSSupplier<InputStream>() {
		    @Override
		    public InputStream supply() {
		        try {
					return new FileInputStream("F:\\logs\\NotoSansCJKtc-Regular.ttf");//從第3點裏下載的字體
				} catch (FileNotFoundException e) {
					e.printStackTrace();
				}
		        return null;
		    }
		}, "cjk", 400, FontStyle.NORMAL, true);
		builder.useUnicodeBidiSplitter(new ICUBidiSplitter.ICUBidiSplitterFactory());
		builder.useUnicodeBidiReorderer(new ICUBidiReorderer());
		builder.defaultTextDirection(TextDirection.LTR);
		builder.toStream(os);
		builder.run();
	}

5. Html上記得加下font-family

	font-family: 'cjk';
