一、环境：

1、freemarker 2.3.21版本；

2、itext 2.1.7版本；

3、flying-saucer-core 11.0.7版本；

二、实现代码：

      map, String basePath, String fontFile) throws IOException, TemplateException, ParserConfigurationException, DocumentException, SAXException {	/** ----freemarker模板解析---- **/	Configuration configuration = new Configuration(Configuration.VERSION_2_3_21);	configuration.setDefaultEncoding("utf-8");	StringTemplateLoader stringLoader = new StringTemplateLoader();	stringLoader.putTemplate(templateName, templeteBuffer);	configuration.setTemplateLoader(stringLoader);	Template template = configuration.getTemplate(templateName);	StringWriter str = new StringWriter();	template.process(template, str);	/** -------生成PDF------- **/	DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();	Document doc = builder.parse(new ByteArrayInputStream(str.toString().getBytes()));	ITextRenderer renderer = new ITextRenderer();	renderer.setDocument(doc, null);	// 解决中文支持问题	ITextFontResolver fontResolver = renderer.getFontResolver();	String simusun = fontFile;	if (simusun != null) {	    fontResolver.addFont(simusun, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);	    renderer.getSharedContext().setFontResolver(fontResolver);	}	// 解决图片的相对路径问题	renderer.getSharedContext().setBaseURL("file:" + basePath);	renderer.layout();		//返回PDF字节数组 一边上传文件服务器	ByteArrayOutputStream os = new ByteArrayOutputStream(1024000);	renderer.createPDF(os);	// 输出PDF文件	// OutputStream fileStream = new FileOutputStream("d:\\test.pdf");	// fileStream.write(os.toByteArray());	// fileStream.close();	return os.toByteArray();    }}

示例：

freemarker test.ftl

    	
    
		
     
			
      页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉页眉		
     
		
     
			
      
       第
       页，共页
      
			
      页底页底页底页底页底页底页底页底页底页底页底页底页底页底页底页底页底页底		
     
		
     
		
     
			
      
				<#list insurantList as insurant>					
				       
        
         
编号1
         
名称
         
编号2
         
编号3
        
        
         
${insurant.inssueNum}
         
${insurant.cname}
         
${insurant.cardNum}
         
${insurant.brithday}
        
				        			       
      
		
     
			
    

生成的pdf效果：

图中有间隔是用两张图拼的，中间页就省略；

实现了页眉与页底+分页显示效果；
