Java-Reflection反射-获取包括父类在内的所有字段

public static  Map ClassToMap(T className, Class entityClass) {
        List fieldList = new ArrayList<>() ;
        Class tempClass = entityClass;
        while (tempClass != null) {//当父类为null的时候说明到达了最上层的父类(Object类).
            fieldList.addAll(Arrays.asList(tempClass .getDeclaredFields()));
            tempClass = tempClass.getSuperclass(); //得到父类,然后赋给自己
        }
        for (Field f:fieldList) {
            System.out.println("getFields---"+f.getName());
        }
}
