当我尝试将我的Web应用程序部署到tomcat时,我需要帮助来修复这个错误.为什么不定义customerService bean？我在我的web.xml中缺少某些东西,还是要以某种方式映射customerService？我正在使用注释进行映射.任何帮助将不胜感激.以下是本地主机日志中的错误日志条目：

客户服务
package testapp.mis.service;

public interface CustomerService {
public List<Customer> retrieveAllCustomerNames();
public List<Customer> retrieveAllCustomerCountries();
public void createCustomer(Customer customer);

}
感谢您的帮助,让我知道如果我需要安装任何其他文件.
编辑：这里是applicationContext.xml和customerService实现文件：

解决方法
通过阅读您的异常,确保您忘记了自动连接customerService
您应该自动连线您的客户服务.
在控制器类中进行以下更改
@Controller
public class CustomerController{
@Autowired
private Customerservice customerservice;
......other code......
}
再次你的服务实现类
写
@Service
public class CustomerServiceImpl implements CustomerService {
@Autowired
private CustomerDAO customerDAO;
......other code......
.....add transactional methods
}
如果您正在使用hibernate,则需要在applicationcontext xml文件中进行必要的更改(需要配置会话工厂).
您应该在您的DAO实现中自动连接sessionFactory set方法
