Zk java代码生成器
比如你有一个index.zul页面，代码如下：
给这个主程序类传5个参数，就可以得到最终的java文件。
java生成器代码：
指定5个参数分别是：
args[0] = "D:/javacreator/zul/example/";
args[1] = "index.zul";
args[2] = "D:/javacreator/java/example/";
args[3] = "Hello.java";
args[4] = "com.yourcompany.example";
最后D:/javacreator/java/example/目录下生成的Hello.java文件代码：
给这个主程序类传5个参数，就可以得到最终的java文件。
java生成器代码：
