模板存放的只是文本。模板能包括引用变量和groovy代码。groovy的模板引擎提供了createTemplate 方法来实现Strings, Files, Readers or URL，返回的是Template 对象。
Template 对象通常用来创建最终的文本。Template 调用make方法，返回的是Writable，而make方法中传入的是键值对的map，而该map是传入模板的变量名及对应的值。

package template
import groovy.text.SimpleTemplateEngine
class TemplateTest {
static main(args) { String templateText = ‘‘‘Project report:
We have currently ${tasks.size} number of items with a total duration of $duration. <% tasks.each{%> - $it.summary; <%}%> ‘‘‘;
def list = [ new Task(summary:"Learn Groovy",duration:4), new Task(summary:"Learn Grails",duration:12) ]; def totalDuration = 0; list.each {totalDuration+=it.duration}; def engine = new SimpleTemplateEngine(); def template = engine.createTemplate(templateText); def binding = [ duration:"$totalDuration", tasks:list ]; println (template.make(binding)).toString(); }
}
