获取一个实体类的所有非静态属性

private static List<Field> getAllField(Class<?> entityClass, List<Field> fieldList) {
        if (fieldList == null) {
            fieldList = new ArrayList<Field>();
        }
        if (entityClass.equals(Object.class)) {
            return fieldList;
        }
        Field[] fields = entityClass.getDeclaredFields();
        for (Field field : fields) {
            //排除静态字段
            if (!Modifier.isStatic(field.getModifiers())) {
                fieldList.add(field);
            }
        }
        Class<?> superClass = entityClass.getSuperclass();
        if (superClass != null
                && !superClass.equals(Object.class)
                && (superClass.isAnnotationPresent(Entity.class)
                || (!Map.class.isAssignableFrom(superClass)
                && !Collection.class.isAssignableFrom(superClass)))) {
            return getAllField(entityClass.getSuperclass(), fieldList);
        }
        return fieldList;
    }
