java中获取bean中所有的属性

 public static void main(String[] args) {
   PropertyDescriptor[] props = null;
         try {
             props = Introspector.getBeanInfo(new Gdzcn().getClass(), Object.class)
                     .getPropertyDescriptors();
         } catch (IntrospectionException e) {
         }
         if (props != null) {
             for (int i = 0; i < props.length; i++) {
                 try {
                    String aa = props[i].getName();//获取bean中的属性
                    Object object = props[i].getPropertyType();//获取属性的类型
                    } catch (Exception e) {
                 }}}}
