groovy : 读 java bean 输出属性

javabean.groovy  可用于 jsp,freemarker 输出表格

import java.io.File

if (args.size() <1){
    println " usage:groovy javabean Bean.java var ";
    return
}
def f1 = args[0];
def var ='';
def i =0;
if (args.size() ==2){ var = args[1];}
else { i = f1.indexOf('.'); 
	var = f1.substring(0,i).toLowerCase();
}
def alist =[];
new File(f1).eachLine { line ->
	alist = line.replace(';','').trim().split();
	if (alist.size()>=3 && alist[0]== "private"){
		if (alist[1]== "String"){
			println "  <td>\${ ${var}.${alist[2]} }</td>";
		} else {
			println "  <td align=\"right\">\${ ${var}.${alist[2]} }</td>";
		}
	}
}
