ssm事务开启失败，网上查找资料任然未解决
问题遇到的现象和发生背景
在学习ssm集合框架的时候，搭建了一个小型的ssm项目，用以熟悉ssm框架，在准备开启ssm框架的事务时，无法开启事务。
出现问题后在网上查找问题，搜到如下解决方案：
1：区分springmvc容器和spring父容器的扫描范围，防止事务失效。
2：@Transactional后添加 propagation = Propagation.REQUIRED, rollbackFor = Throwable.class属性。
3：开启注解事务的时候 属性修改为 proxy-target-class="true"
以上解决方案均未解决我项目的问题。
以下为我项目的项目结构
以下为我项目的配置文件 spring-dao.xml,spring-web.xml,spring-service.xml,web.xml,mybatis-config.xml

以下为我的测试文件
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)
@Service
@Component
public class Bookservice {
@Autowired
private BookDao bookDao;
@Autowired
private UserBook userBook;
@Autowired
private Book book;
@Autowired
private User user;
@Qualifier("UserBookDao")
@Autowired
private UserBookDao userbookDao;
private static Bookservice bookservice;
@PostConstruct //通过@PostConstruct实现初始化bean之前进行的操作
public void init() {
bookservice = this;
}
@Test
public void insertT(){
bookservice.book.setName ("测试名称");
bookservice.book.setAuthor ("我1");
bookservice.book.setFileUrl ("文件路径");
bookservice.book.setImg ("图谱路径");
bookservice.bookDao.add (bookservice.book);
throw new RuntimeException("huigun");
}
希望能帮我解决这个问题，不甚感激
别搞这些花里胡哨的东西，自己去写代码调用这个方法，再看结果
