Hibernate + Spring事务回滚不起作用答案

【问题描述】：

当服务抛出配置为回滚（rollbackfor）的异常时，此回滚不起作用。

服务类：

@Service("bookService")
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = { BusinessException.class }, readOnly = true)
public class BookServiceImpl implements BookService {

    @Autowired
    private BookRepository bookDAO;

     @Override
     @Transactional(readOnly = false)
     public void transactionTest(Book book) throws BusinessException {
          try {
               bookDAO.test(book);
          } catch (DAOException e) {
               throw new BusinessException("test rollback - service");
          }
     }
}

存储库类：

@Repository("bookRepository")
public class BookRepositoryImpl implements BookRepository {

    @Autowired
    private SessionFactory sessionFactory;

@Transactional(readOnly = false)
@Override
public Book saveOrUpdate(Book book) {
    if (book.getId() != null) {
        getSession().merge(book);
    } else {
        getSession().save(book);
    }
    return book;
}

@Transactional(readOnly = false)
@Override
public void test(Book book) throws DAOException {

    saveOrUpdate(book);
    System.out.println(book.getTitle() + " inserted!");
    throw new DAOException("Test rollback");
}

}

回滚在一种情况下有效。为此，我需要更改 BookServiceImpl 删除 readOnly = true 并删除“transactionTest”方法的“@Transactional(readOnly = false)”。但出于安全原因，我希望对所有类都使用 readOnly = true 并指定使用 readOnly = false 的方法是什么

【解决方案1】：

目前整个BookServiceImpl事务配置为@Transactional(propagation = Propagation.REQUIRED, rollbackFor = { BusinessException.class }, readOnly = true)

而对于transactionTest，重写的注解是@Transactional(readOnly = false)，当您使用类重写注解以更新方法的整个注解而不是仅指定属性时。

而不是这个，你应该有下面BookServiceImpl的代码

@Service("bookService")
@Transactional(readOnly = true)
public class BookServiceImpl implements BookService {

    @Autowired
    private BookRepository bookDAO;

     @Override
     @Transactional(propagation = Propagation.REQUIRED, rollbackFor = { BusinessException.class },readOnly = false)
     public void transactionTest(Book book) throws BusinessException {
          try {
               bookDAO.test(book);
          } catch (DAOException e) {
               throw new BusinessException("test rollback - service");
          }
     }
}

如果您想要在 DAO（存储库）级别上进行相同类型的事务，请指定它或让服务来处理事务（假设存储库不会直接与客户端交互）。
