把java实体转成flex用的as实体

自己用的一个小工具，可以根据需要扩展

import java.io.File;

	// POJO的包路径
	private static String JAVA_PACKAGE = "com.test.entity";

	// 将要生成的as的value object包路径
	private static String FLEX_PACKAGE = "flex.actionScript";

  // 需要过滤掉以此后缀结尾的实体（因为我们用的是ibatis持久层，abator生成的实体包括两个，一个是实体本身，一个是用于拼sql的Example类，需要去掉以Example结尾的类）
