我有个问题.我使用Spring Hibernate,我无法处理标记为@Transactional的方法中的异常.以前,当我使用Spring JDBC时,一切工作都很好.
DAO类标有@Repository.
这是我旧代码的秘密.
在服务中：
@Transactional(readOnly = false,propagation = Propagation.REQUIRES_NEW,rollbackFor = {Exception.class})
public boolean bookTickets(Integer userId,List
在道：
@Transactional(propagation = Propagation.MANDATORY)
public void bookTicket(Ticket ticket,final int userId) {
MapsqlParameterSource map = new MapsqlParameterSource();
map.addValue(Constants.TABLE_BOOKING.FIELD_TICKET_ID,ticket.getId());
map.addValue(Constants.TABLE_BOOKING.FIELD_USER_ID,userId);
int rowsAffected = template.update(QUERY_INSERT_BOOKING,map);
if (LOG.isTraceEnabled()) {
LOG.trace("Affected " + rowsAffected + " rows.");
}
}
现在我将我的DAO从Spring JDBC移到hibernate 3上.
这就是我现在拥有的.
在服务中：
@Transactional(readOnly = false,rollbackFor = {Exception.class})
public boolean bookTickets(Integer userId,List在道：
@Override
public void bookTicket(Booking booking) {
getHibernateTemplate().save(booking);
}
问题是我无法在服务方法中处理try-catch块中的异常.他们直接投入我的控制器.
我认为问题在于Spring JDBC中的事务管理器org.springframework.jdbc.datasource.DataSourceTransactionManager和hibernate中的org.springframework.orm.hibernate3.HibernateTransactionManager,但是我没有任何想法如何克服这个问题,所以我需要你的帮助.
更新后.增加的例外情况.

有没有办法处理服务层内的异常？
谢谢.
最佳答案
