使用ssh框架的时候,怎么做单元测试

这次发现在SSM中,用单元测试类的写法,在hibernate中行不通了,因为有事物管理范围的限制问题(出了spring,springmvc的扫描范围,就不处于事物管理范围之内了,所以在单元测试类中,就不能调用service中的查询数据库的方法,然后再把查出来的对象放到要测试的方法中)

解决方案:  
将单元测试类,也纳入事物管理的范围之内

package com.xxx.service.impl;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    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.web.WebAppConfiguration;
    import org.springframework.transaction.annotation.Transactional;
    
    import com.xxx.bill.service.ReceiveInformationFromWuZhongService;
    import com.xxx.orm.entity.Bill;
    import com.xxx.service.BillService;
    import com.xxx.entity.WZ_API_Books;
    
    //测试web的时候,需要使用这两个
    //@ContextConfiguration(locations = { "classpath:config/applicationContext*.xml", "classpath:config/springmvc.xml" })
    //@WebAppConfiguration
    @ContextConfiguration(locations = { "classpath:config/applicationContext*.xml"})
    @RunWith(SpringJUnit4ClassRunner.class)
    @Transactional
    //测试数据,默认会回滚,若不想回滚,则需要设置为如下
    @Rollback(false)
    public class ReceiveInformationFromWuZhongServiceImplTest {
        Logger logger = LoggerFactory.getLogger(this.getClass());
        @Autowired
        ReceiveInformationFromWuZhongService receiveInformationFromWuZhongService;
        @Autowired
        BillService billService;
    
        @Test
        public void testReceiveInformationFromWuZhong(){
            Bill bill = billService.getById(1L);
            String caseId = bill.getCaseId();
            String type = "2";
            String status = "2";
            List<WZ_API_Books> books = new ArrayList<WZ_API_Books>();
            WZ_API_Books book = new WZ_API_Books();
            books.add(book);
            boolean resutl = receiveInformationFromWuZhongService.receiveInformationFromWuZhong(bill, caseId, type, status, books);
        }
    }
