?部分Action.vm代碼：

???HttpServletRequest?request,?HttpServletResponse?response)
??? throws ?Exception? ... {

??logger.debug( " ---?edit${className}?start?--- " );
??checkToken(request);
??$ ... {className} Form?$ ... {className.toLowerCase()} Form? = ?($ ... {className} Form)form;

action.properties:

A = Jaaas
B = Jbbbs
C = Tcccs

采用velocity根據(jù)模塊自動(dòng)生成java類
