Groovy main方法

	public static void main(def args){
		// TODO Auto-generated method stub
		def greeting ='hello'
		def clos = {param->println "${greeting} ${param}"}
		clos.call('world')
		
		greeting ='Welcome'
		clos.call('world')
		
		demo(clos)
		}
	
	def demo(clo){
		def greeting ='Bonjour'
		clo.call('ken')
	}



hello world
Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: static com.cenyol.example.controller.Groovy1.demo() is applicable for argument types: (com.cenyol.example.controller.Groovy1$_main_closure1) values: {com.cenyol.example.controller.Groovy1$_main_closure1@2fcac6db}
	at groovy.lang.MetaClassImpl.invokeStaticMissingMethod(MetaClassImpl.java:1155)

Groovy中 main方法不能引用其他方法。

抛出异常： 

 No signature of method: static com.cenyol.example.controller.Groovy1.demo()

嵌套在groovy中不试用

这样更改代码后没有嵌套：

public class Groovy1{


	/**
	 * @param args
	 */	
	public static void main(def args){
		// TODO Auto-generated method stub
		def greeting ='hello'
		def clos = {param->println "${greeting} ${param}"}
		clos.call('world')
		
		greeting ='Welcome'
		clos.call('world')
		def aa = new test1()
		aa.demo(clos)
		}
}

		public class test1{
			def demo(clo){
				def greeting ='Bonjour'
				clo.call('ken')
		}
		}

打印结果：

hello world
Welcome world
Welcome ken

注意是welcome ken
