Java反射获取Object的属性和值,包括单个对象

public class IsObjectEmpty {

    public static HashMap<String,String>  isObjectFiledEmpty(UserProfile.Diet object) throws Exception{
        HashMap<String,String> map=new HashMap<>();

        Class<?> clazz= object.getClass();
        Field[] fs=clazz.getDeclaredFields();

        for(Field field:fs){
            field.setAccessible(true);
            if(field.get(object)!=null){
                String name=(String)field.getName();
                map.put(name,field.get(object).toString());
            }
        }
        return map;
    }
}
