//2 Create a Context object

VelocityContext context = newVelocityContext();

//3 Add you data object to this context

context.put("title", "银联电子");

context.put("body", "这是内容"); 

//4 Choose a template

Template template =Velocity.getTemplate("file.vm");

//创建文件

File saveFile = newFile("G:\\workspace\\zjq\\velocity\\WebRoot\\page\\test.html");

//获得它的父类文件，如果不存在，就创建

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


saveFile.getParentFile().mkdirs();

}

//创建文件输出流

FileOutputStream outStream = newFileOutputStream(saveFile);

//因为模板整合的时候，需要提供一个Writer，所以创建一个Writer

OutputStreamWriter writer = newOutputStreamWriter(outStream);

//创建一个缓冲流

BufferedWriter bufferWriter = newBufferedWriter(writer);



//5 Merge the template and you data toproduce the output

template.merge(context, bufferWriter);

bufferWriter.flush();//强制刷新

outStream.close();

bufferWriter.close();

file.vm
