Velocity's 9th application example --- format date

To extend the function, you can write a tool class, and then put the tool class in the context. You can directly call the tool class method in the template

By default, the date output is Tue
Jul 14 16:42:30 CST 2015

We need to write a tool class to format the date,

Put the original date and date formatting tool class into the context

In the template, call the method of the date formatting tool class to format the date

$dateformat.format("yyyy-MM-dd",$date)



//2 Create a Context object

VelocityContext context = newVelocityContext();

//3 Add you data object to this context

context.put("date", new Date());

//扩展功能，提供一个日期格式工具类，在模板中调用其方法即可。

context.put("dateformat", newDateUtils());

//4 Choose a template

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

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

StringWriter sw = new StringWriter();

template.merge(context, sw);

sw.flush();

System.out.println(sw.toString());



formatedate.vm

${date}
