• IntroSpector，操作javabean
• 例子

  • Point p = new Point();
    PropertyDescriptor pd = new PropertyDescriptor("x", p.getClass());
    Method methodGetX = pd.getReadMethod();
    Method methodSetX = pd.getWriteMethod();
    methodSetX.invoke(p, 7);
    System.out.println(methodGetX.invoke(p));
     
    BeanInfo beanInfo = Introspector.getBeanInfo(p.getClass());
    PropertyDescriptor[] pds = beanInfo.getPropertyDescriptors();
    for(PropertyDescriptor pd2 : pds){
        if(pd.getName().equals("x")){
            System.out.println(pd.getReadMethod().invoke(p));
            break;
        }
    }
