我需要帮助解决我在尝试将我的 Web 应用程序部署到 tomcat 时遇到的这个错误。为什么没有定义 customerService bean？我是否在 web.xml 中遗漏了某些内容，或者我是否必须以某种方式映射 customerService？我正在使用注释进行映射。任何帮助将非常感激。这是来自本地主机日志的错误日志条目:

这是客户 Controller 。我按照建议添加了@Autowired。

@Controller
@RequestMapping("/customer")
public class CustomerController {
/*@Resource(name="customerService")
private CustomerService customerService;
*/
@Autowired
private CustomerService customerService;
@RequestMapping(value="/list", method=RequestMethod.GET)
public String getCustomerList(Model model) {
List<Customer> customers = customerService.retrieveAllCustomers();
System.out.println("test");
model.addAttribute("customerList", customers);
return "customer";
}
@RequestMapping(value="/add", method=RequestMethod.GET)
public String getCustomer(Model model) {
model.addAttribute("customerAttribute", new Customer());
return "new-customer";
}

最佳答案
通过阅读您的异常，可以确定您忘记了 autowire customerService
您应该自动连接您的客户服务。
在您的 Controller 类中进行以下更改
@Controller
public class CustomerController{
@Autowired
private Customerservice customerservice;
......other code......
}
再说一遍你的服务实现类
写
@Service
public class CustomerServiceImpl implements CustomerService {
@Autowired
private CustomerDAO customerDAO;
......other code......
.....add transactional methods
}
如果您使用 hibernate ，请在您的 applicationcontext xml 文件中进行必要的更改(需要配置 session 工厂)。
你应该在你的 DAO 实现中 Autowiring sessionFactory 设置方法
