JAva出力PDFドキュメント

PDF出力はiTextパッケージに使用されます.PDFドキュメントの特殊性のため、ローカルのフォントサポートが必要になる場合があります.Webアプリケーションでは、サーバ側にフォントパッケージを配置する必要がある場合があります.
一般的な出力PDFには2つの方法があります
1つ目は、adobe lifecycle処理を経て、固定されたテンプレートを構築する必要があります.テキストを入力する場所にテキストボックスを追加します.(固定サイズのみ)、テキストボックスの枠線を外し、属性をreadonlyに変更します.pageの名前とテキストボックスのnameを設定することに注意してください.文字があまり多くないことを保証しなければなりません.そうしないと、テキストボックスが完全に表示されません.中国語が表示されない場合は、lifecycleでテキストボックスフォントを中国語フォントに設定してみてください.例コードは以下の通りです.

File file = new File("d:\\aaa.pdf");//      
		OutputStream os = new FileOutputStream(file);//       ,   jsp  ,     response      
		PdfReader reader = new PdfReader("d:/Untitled3.pdf", null); //  pdf  
		PdfStamper ps = new PdfStamper(reader, os); //    PdfStamper  
		AcroFields af = ps.getAcroFields();//   pdf     
		//    
		BaseFont bfchinese = BaseFont.createFont("SIMFANG.TTF",BaseFont.IDENTITY_H, BaseFont.EMBEDDED);//      
		af.setFieldProperty("Page1.t1", "textfont",bfchinese, null);//    
		af.setFieldProperty("Page1.t1","textsize",11,null); //      
		af.setField("Page1.t1","   "); //       
		
		af.setFieldProperty("Page1.t2", "textfont",bfchinese, null);//    
		af.setFieldProperty("Page1.t2","textsize",11,null); //      
		af.setField("Page1.t2","   "); //       
		
		af.setFieldProperty("Page1.t3", "textfont",bfchinese, null);//    
		af.setFieldProperty("Page1.t3","textsize",11,null); //      
		af.setField("Page1.t3","24"); //       
		//    
		ps.close();
		os.flush();
		os.close();
		//done
		System.out.println("done..");

 
2つ目の方法は、コードから直接PDFファイルを生成することです.操作は少し煩雑で、テンプレートのサポートは必要ありません.サンプルコードは以下の通りです.
