1.框架结构

spring +spring mvc+mybatis idea

2.例子如下（仅供参考使用）：

import com.raipeng.sales.entity.Sales;import com.raipeng.sales.front.repository.SalesRepository;import org.junit.Assert;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.annotation.Rollback;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.transaction.TransactionConfiguration;import org.springframework.transaction.annotation.Transactional;import java.util.Date;import java.util.HashMap;import java.util.List;import java.util.Map;/** * Created by 111 on 2015/11/28. */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = "classpath:applicationContext.xml")@Transactional@TransactionConfiguration(transactionManager = "transactionManager" ,defaultRollback = true)public class SalesDaoTest {    @Autowired    public SalesRepository salesRepository;    @Test    public void testFindList(){        List<Sales> salesList = salesRepository.findSalesListBySalesId(1l);        System.out.println(salesList.size());    }    @Test    @Rollback(value = false)    public void testUpdateSales(){        Sales sales = salesRepository.findSalesBySalesId(1l);        sales.setCashStatus(1);        sales.setAmount("9999.99");        int num = salesRepository.updateSalesBySales(sales);        System.out.println(num+"___________");    }}

3.spring整合junit需要注意的是：

spring只对junit4.5以上版本支持，否则@RunWith这个注解是无法引用的；
