构建Attribute时,将分类属性加载入hashtable,构建模型时,将用到的分类属性与hashtable中的记录进行对比,失败报错
Attribute gender = new Attribute( "Weight", genderCategory);public DataObject delegator(String className, String methodName,
DataObject para) throws Exception{ //查找客户化表,获取客户化的类String customClassName = getCustomClass(className);//查找客户化表,获取客户化的方法String customMethodName = getCustomMethod(methodName);Class<?> c = Class.forName(customClassName);//获取客户化的类的实例Object o = c.newInstance();Method m = o.getMethod(customMethodName, DataObject.class);DataObject result;try{ //执行客户化的方法 result = m.invoke(o, para);} catch(InvocationTargetException e)[ throw e.getCause();}return result;}
