spring mvc 事务

applicationContext.xml:

<context:component-scan base-package="com.ssh,com" >
    
    </context:component-scan>


springMvc-servlet.xml
<!-- 自动扫描的注解包名，用，隔开 -->
<context:component-scan base-package="com.ssh,com" >
     <context:exclude-filter type="annotation"  expression="org.springframework.stereotype.Service" />
    </context:component-scan>


------------------------------------------
服务类：
@Transactional(rollbackFor=Exception.class) ，若没配，则无事务。在接口配置，也无事务。服务类非接口方法也无事务，如private

// @Transactional(rollbackFor=Exception.class)
public void testRollback() throws Exception{
//插入数据1
TBatTaskLog bean = new TBatTaskLog();
bean.setBatchNo("11111");
bean.setBranchNo("11111");
bean.setCreateTime(new Date());
bean.setCreator("a");
bean.setInstanceId("111111111");
bean.setMessage("abc");
bean.setSeqNo(5);
hbmBaseDao.save(bean);
LogUtil.println("a#####################1");
//插入数据2
TBatInstPre beanpre = new TBatInstPre();
beanpre.setInstanceId("111111111");
beanpre.setPreInstanceId("aaaaaaaaaaa");
this.hbmBaseDao.save(beanpre);
LogUtil.println("a#####################2");

//抛异常
throw new Exception("abccc");
