Bean property ' ' is not writable or has an invalid setter method原因

Bean property ' ' is not writable or has an invalid setter method. 
Does the parameter type of the setter match the return type of the getter?           

 原因是我的service实现中没有注入dao

注入即可：

private ShopRewardRecordDao shopRewardRecordDao;
	
public void setShopRewardRecordDao(ShopRewardRecordDao shopRewardRecordDao) {
	this.shopRewardRecordDao = shopRewardRecordDao;
}
