我有以下 AccountController 类
@Controller
@RequestMapping("/rest/accounts")
public class AccountController {
private AccountService accountService;
@Autowired
public AccountController(AccountService accountService) {
this.accountService = accountService;
}
... implemented methods here
}
AccountService类如下
public interface AccountService {
public Account findAccount(BigInteger id);
public Account createAccount(Account data);
public Account deleteAccount(String email);
public Boolean updateAccount(String email,String password);
public List<Account> findAllAccounts();
// public Account deleteAccount();
public Customer createCustomer(String accountId, Customer data);
public List<Customer> findCustomersByAccount(String accountId);
}
AccountServiceImpl类如下
@Service
公共(public)类 AccountServiceImpl 实现 AccountService{
@Autowired
private AccountRepository accountRepo;
@Autowired
private CustomerRepository custRepo;
..implemented methods here
}
我的 servlet.xml 有以下组件扫描
<context:component-scan base-package="com.sam.spring.web.rest.mvc" />
/src/resource/context.xml 具有以下内容
<context:component-scan base-package="com.sam.spring.web.core.services"></context:component-scan>
<context:component-scan base-package="com.sam.spring.web.core.repositories.jpa"></context:component-scan>
我收到以下错误:
org.springframework.beans.factory.BeanCreationException: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'accountController' defined in file ...
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.sam.spring.web.core.services.AccountService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
我在这个设置中做错了什么？
最佳答案
试试这个 <context:component-scan base-package="com.sam.spring.web.rest.mvc, com.sam.spring.web.core.services, com.sam.spring.web.core.repositories.jpa" />
