百度了很多解决方案，都是说 @ Service忘记写了，或者没加

<context:component-scan base-package="com.ws.merchant" />
但是我都加了，表示很无奈
下面是我的一些代码

package com.ws.merchant.service.impl;



import javax.annotation.Resource;



import org.springframework.stereotype.Service;



import com.ws.merchant.dao.MerchantDao;

import com.ws.merchant.model.Merchant;

import com.ws.merchant.service.MerchantService;



/**

 * 商户service实现类

 *

 * @author lds

 * @date 2018-1-12

 *

 */

@Service("MerchantService")

public class MerchantServiceImpl implements MerchantService{

	

	@Resource

	private MerchantDao merchantDao;



	@Override

	public Merchant getMerchById(String id) {

		// TODO Auto-generated method stub

		return merchantDao.selectMerchant(id);

	}



	@Override

	public int addMerchant(Merchant merch) {

		// TODO Auto-generated method stub

		return merchantDao.insertMerchant(merch);

	}



	@Override

	public int deleMerchant(String id) {

		// TODO Auto-generated method stub

		return merchantDao.deleMerchant(id);

	}



}
