我有以下错误，当我尝试存取权限进入主网页错误创建名为“userService”豆：不满意依赖通过现场“userJpaRepository”
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService': Unsatisfied dependency expressed through field 'userJpaRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'net.codejava.spring.repository.UserRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=userJpaRepository)}
在我UserController中我有下面的代码
表达@Controller
public class UserController {
private UserService employeeServiceImpl;
@RequestMapping("/")
public String employee() {
this.employeeServiceImpl.listAlUsers();
return "employee";
}
@Autowired(required = true)
public void setEmployeeService(UserService employeeServiceImpl) {
this.employeeServiceImpl = employeeServiceImpl;
}
}
我UserService
public interface UserService {
public abstract List<User> listAlUsers();
public abstract User addUser(User user);
public abstract int removeUser(int id);
public abstract User updateUser(User user);
}
我UserServiceImpl
@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired
@Qualifier("userJpaRepository")
private UserRepository userJpaRepository;
@Override
public List<User> listAlUsers() {
return userJpaRepository.findAll();
}
@Override
public User addUser(User user) {
return userJpaRepository.save(user);
}
@Override
public int removeUser(int id) {
userJpaRepository.delete(id);
return 0;
}
@Override
public User updateUser(User user) {
return userJpaRepository.save(user);
}
}
我JpaRepository
@Repository("userJpaRepository")
public interface UserRepository extends JpaRepository<User,Serializable> {
}

根上下文是空的。
我不知道错误的可能原因在哪里我试图找到不同的选项，但如果我使用DAO模式，我收到相同的错误，所以我想知道哪个是要解决的问题。
该项目的配置与XML，但我认为没有解决这个情况很重要。
商祺！
XML是非常重要的该存储库没有自动装配，因此请将其发布。你在任何地方使用注释都不知道你为什么要使用xml配置。 – lsiva
