velocity第四个应用例子---遍历Map集合



//2 Create a Context object

VelocityContext context = newVelocityContext();

//3 Add you data objects to this context

Map<String,String> map = newHashMap<String,String>();

map.put("key1","value1");

map.put("key2","value2");

map.put("key3","value3");

map.put("key4","value4");

context.put("map", map);

//4 Choose a template

Template template =Velocity.getTemplate("map.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());

 

模板

#foreach($keyin $map.keySet())

   $key:$map.get($key)

#end
