使用iText5.x创建PDF中文处理问题
今天无意中在网上看到iText这个东东，iText 是利用Java 来操作PDF 操作的一种开源API
简单说明下使用该API创建PDF文件的过程
PS：使用的是iText5.x版本
/**
* 创建PDF文件
* @param filePath 文件路径
* @param content 需要写入的内容
* @throws DocumentException
* @throws IOException
*/
public void createPdf(String filePath ,String content) throws DocumentException, IOException{
//1.创建Document对象
Document document = new Document();
FileOutputStream fos = new FileOutputStream(filePath);
//2.创建一个PdfWriter实例
PdfWriter.getInstance(document, fos);
//3.打开文档
document.open();
Paragraph graph = new Paragraph(content);
//4.加入段落
document.add(graph);
//5.关闭文档
document.close();
}
利用上述程序，运行结果。发现，只有英文部分被写入，中文部分无法被写入。百度得到结论：
需要加入itextasian.jar包，itextasian.jar包有实现了对中文字体的支持。因此加载itextasian.jar到classpath下。
在上述代码中加入如下代码：
BaseFont baseFontChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
Font fontChinese = new Font(baseFontChinese , 12 , Font.NORMAL);
Paragraph graph = new Paragraph(content , fontChinese);
运行，得到如下异常：
Font 'STSong-Light' with 'UniGB-UCS2-H' is not recognized
还是不行，继续研究，在网上前辈们说如下原因：
| iText5.x版本以上中的font和encoding文件都是从String RESOURCE_PATH = "com/itextpdf/text/pdf/fonts/"加载的,而老itextasian.jar的包名是com.lowagie.text.pdf.fonts, 包名不一致导致路径错误,。 |
具体解决方法就是修改包的路径了,详细方法如下：
|
1.解压iTextAsian.jar 得到如下目录： iTextAsian --com --lowagie --text --fonts --...(字体属性文件) 2.将解压后的com目录下的包名lowagie更改为itextpdf 3.在命令行转至iTextAsian目录，重新打包为iTextAsian.jar文件 4.打包命令如下： jar cvf iTextAsian.jar com/itextpdf/text/pdf/fonts/* 5.执行后，将新的iTextAsian.jar加入classpath路径 |
运行结果,OK,解决问题。
最终代码如下：
/**
* 创建PDF文件
* @param filePath 文件路径
* @param content 需要写入的内容
* @throws DocumentException
* @throws IOException
*/
public void createPdf(String filePath ,String content) throws DocumentException, IOException{
//1.创建Document对象
Document document = new Document();
FileOutputStream fos = new FileOutputStream(filePath);
//2.创建一个PdfWriter实例
PdfWriter.getInstance(document, fos);
//3.打开文档
document.open();
BaseFont baseFontChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
Font fontChinese = new Font(baseFontChinese , 12 , Font.NORMAL);
Paragraph graph = new Paragraph(content , fontChinese);
document.add(graph);
document.close();
}
继续研究ing~~

请问～ itextAsian只要进行buildpath就ok了么？ 我还是会出现not found的情况
2010年10月18日 06:08
@Hey: 是的，在Build Path中加入itextasian.jar或者把这个包引用进来，你的可能是版本问题。
