我用的是：sql2java-2-2-1， 在看了其开发向导后有句：
The writers property define the JavaWriter class to use. com.bitmechanic.sql2java.JavaWriter is an abstract class that you subclass to define how the mapping classes should be generated. sql2java ships with several subclasses of JavaWriter, but you are encouraged to use these as a base, and write your own if you wish.
不知这个类怎么样写， 先谢了。
