2、获取模板内容并填充数据

public static String getContent(String fileName,Object data){

String templatePath=getPDFTemplatePath(fileName).replace("\\", "/");

String templateFileName=QPaPBQxUDgetTemplateName(templatePath).replace("\\", "/");

String templateFilePath=getTemplatePath(templatePath).replace("\\", "/");

System.out.println("templatePath:"+templatePath);

System.out.println("templateFileName:"+templateFileName);

System.out.println("templateFilePath:"+templateFilePath);

if(StringUtils.isEmpty(templatePath)){

throw new FreeMarkerException("templatePath can not be empty!");

}

try{System.out.println("进到这里了，有来无回1");

Configuration config = new Configuration(Configuration.VERSION_2_3_25);

config.setDefaultEncoding("UTF-8");

config.setDirectoryForTemplateLoading(new File(templateFilePath));

config.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);

config.setLogTemplateExceptions(false);System.out.println("进到这里了，有来无回2");

Template template = config.getTemplate(templateFileName);System.out.println("进到这里了，有来无回3");

StringWriter writer = new StringWriter();

template.process(data, writer);

writer.flush();

String html = writer.toString();

return html;

}catch (Exception ex){

throw new FreeMarkerException("FreeMarkerUtil process fail",ex);

}

}

public static String getContent(String fileName,Object data){

String templatePath=getPDFTemplatePath(fileName);//根据PDF名称查找对应的模板名称

String templateFileName=getTemplateName(templatePath);

String templateFilePath=getTemplatePath(templatePath);

if(StringUtils.isEmpty(templatePath)){

throw new FreeMarkerException("templatePath can not be empty!");

}

try{

Configuration config = new Configuration(Configuration.VERSION_2_3_25);//FreeMarker配置

config.setDefaultEncoding("UTF-8");

config.setDirectoryForTemplateLoading(new File(templateFilePath));//注意这里是模板所在文件夹，不是文件

config.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);

config.setLogTemplateExceptions(false);

Template template = config.getTemplate(templateFileName);//根据模板名称 获取对应模板

StringWriter writer = new StringWriter();

template.process(data, writer);//模板和数据的匹配

writer.flush();

String html = writer.toString();

return html;

}catch (Exception ex){

throw new FreeMarkerException("FreeMarkerUtil process fail",ex);

}

}

3、导出模板到PDF文件

/**

* @description 导出pdf到文件

* @param fileName 输出PDF文件名

* @param data 模板所需要的数据

*

*/

public String exportToFile(String fileName,Object data){

try {

String htmlData= FreeMarkerUtil.getContent(fileName, data);

if(StringUtils.isEmpty(saveFilePath)){

saveFilePath=getDefaultSavePath(fileName);

}

File file=new File(saveFilePath);

if(!file.getParentFile().exists()){

file.getParentFile().mkdirs();

}

FileOutputStream outputStream=null;

try{

//设置输出路径

outputStream=new FileOutputStream(saveFilePath);

//设置文档大小

Document document = new Document(PageSize.A4);

PdfWriter writer = PdfWriter.getInstance(document, outputStream);

//设置页眉页脚

PDFBuilder builder = new PDFBuilder(headerFooterBuilder,data);

builder.setPresentFontSize(10);

writer.setPageEvent(builder);

//输出为PDF文件

convertToPDF(writer,document,htmlData);

}catch(Exception ex){

throw new PDFException("PDF export to File fail",ex);

}finally{

IOUtils.closeQuietly(outputStream);

}

} catch (Exception e) {

e.printStackTrace();

}

return saveFilePath;

}

4、测试工具类

public String createPDF(Object data, String fileName){

//pdf保存路径

try {

//设置自定义PDF页眉页脚工具类

PDFHeaderFooter headerFooter=new PDFHeaderFooter();

PDFKit kit=new PDFKit();

kit.setHeaderFooterBuilder(headerFooter);

//设置输出路径
