### 通过注释方式应用事务
```xml
<!-- 启用具有注释的事务划分 然后在类或方法里用@Transactional配置注释使用事务-->
<tx:annotation-driven transaction-manager="transactionManager" mode="proxy" proxy-target-class="true" />
<!-- 启用具有注释的事务划分 -->@Repository
public class StudentDaoImpl implements StudentDao {
@Autowired
private StudentMapper studentMapper;
//这里通过@Transaction定义声明应用事务
@Transactional(propagation = Propagation.REQUIRES_NEW)
@Override
public List<StudentDO> getStudents() {
// TODO Auto-generated method stub
return this.studentMapper.getStudents();
}
}
