Banq,请教如何动态实现标准java bean?

用common属性包可实现如下动态bean,但是假的bean:
DynaProperty[] px = {
new DynaProperty("firstName", Class.forName("java.lang.String")),
new DynaProperty("lastName", Class.forName("java.lang.String"))
};
DynaClass dynaClass = new BasicDynaClass("employee", null, px);

DynaBean employee = dynaClass.newInstance();
PropertyUtils.setProperty(employee, "firstName", "Fred");
PropertyUtils.setProperty(employee, "lastName", "Flintstone");

System.out.println("firstName:" + PropertyUtils.getProperty(employee, "firstName"));
System.out.println("lastName:" + PropertyUtils.getProperty(employee, "lastName"));

由于特殊需要,须按如下反射方式取得bean属性,但系统抛出NoSuchMethodException:

Method method = employee.getClass().getMethod("getLastName", null);
debug(method.invoke(employee, null));

可否告知有无方法实现一个标准规范的bean,即可按反射方式取得属性。
先多谢了。

不是很清楚,标准javabean应该是能编译通过就可以吧?
