对象转Map

public static Map<String, Object> beanToMap(Object object) throws IllegalAccessException {
        Map<String, Object> map = new HashMap<>();
        Field[] fields = object.getClass().getDeclaredFields();
        for (Field field : fields) {
            field.setAccessible(true);
            map.put(field.getName(), field.get(object));
        }
        return map;
}
