解决方案
您的Spring配置中指定的事务管理器，但没有配置应用事务的时间或地点。
在 SpringBean.xml 中，您应取消注释< code $< tx：annotation-driven /> ：
< tx ：annotation-driven transaction-manager =transactionManager/>
然后您应该注释 CustomerServiceImpl.saveCustomer 方法作为 @Transactional ：
@Service
public类CustomerServiceImpl实现CustomerService {
...
@Override
@Transactional
public void saveCustomer（Customer customer）{
customerDaoImpl。 saveCustomer（客户）;
}
...
}
I have a java stuts2 web application using spring and hibernate.

解决方案
You have a transaction manager specified in your Spring config, but no configuration on when or where to apply transactions.
In your SpringBean.xml you should uncomment <tx:annotation-driven/>:
<tx:annotation-driven transaction-manager="transactionManager"/>
And then you should annotate the CustomerServiceImpl.saveCustomer method as @Transactional:
@Service
public class CustomerServiceImpl implements CustomerService {
...
@Override
@Transactional
public void saveCustomer(Customer customer) {
customerDaoImpl.saveCustomer(customer);
}
...
}
