java遍历类的属性和属性值

public static void reflect(Object e) throws Exception {
  Class cls = e.getClass();
  Field[] fields = cls.getDeclaredFields();
  for (int i = 0; i < fields.length; i++) {
    Field f = fields[i];
    f.setAccessible(true);
    System.out.println("属性名:" + f.getName() + " 属性值:" + f.get(e));
  }
}
