java - 创建 bean 时出错

Question

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？

Answer 1

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" />
