java反射获取对象的属性及vale

List<Users> list= Arrays.asList(new Users().setName("Tom").setAge("5205"));
for (Users users : list) {
    Class<?> clazz = users.getClass();
    Map mapResult = new HashMap();
    for (Field field : clazz.getDeclaredFields()) {
        field.setAccessible(true);
        //属性名
        String fieldName = field.getName();
        //对应值
        Object value = (field.get(users));
        System.err.println(fieldName+":"+value);
    }
}
