大家好，我是 spring 的新手，我正在尝试为 CRUD 创建一个简单的应用程序，但我收到了以下错误。我正在使用 STS
在我通过我的解决方案之前，我想列出我尝试过但没有成功的解决方案。
[ java.lang.IllegalArgumentException：不是托管类型
UnsatisfiedDependencyException：创建具有名称的 bean 时出错
合并 bean 定义的后处理失败；嵌套异常是 java.lang.IllegalStateException
但我仍然得到同样的错误
创建名称为“clientServiceImpli”的 bean 时出错：通过字段“clientRepository”表示的依赖关系不满足；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名为“clientReposito”的 bean 时出错：
这是我的代码
// 我的客户回购
@Repository
public interface ClientReposito extends JpaRepository<ClientDao, Long> {
}
//我的实体类
@Entity
//@Table(name = "demande")
public class ClientDao {
@Column(name = "Id")
private int id ;
@Column(name = "groupe")
private String groupe;
@Column(name = "client")
private String Client ;
@Column(name = "quantite")
private int quantite ;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getGroupe() {
return groupe;
}
public void setGroupe(String groupe) {
this.groupe = groupe;
}
public String getClient() {
return Client;
}
public void setClient(String client) {
Client = client;
}
public int getQuantite() {
return quantite;
}
public void setQuantite(int quantite) {
this.quantite = quantite;
}
}
//客户服务
@Service
public interface ClientService {
public void saveUser(ClientDao clientdao);
}
// 客户端服务实现
@Service
public class ClientServiceImpli implements ClientService{
@Autowired
private ClientReposito clientRepository;
@Transactional
public void saveUser(ClientDao clientdao) {
clientRepository.saveAndFlush(clientdao);
}
}
//控制器
@Controller
public class ClientController {
private ClientService clientService;
@Autowired
public void setClientService(ClientService clientService){
this.clientService=clientService;
}
@GetMapping("/index")
public String greeting(@RequestParam(name="name", required=false, defaultValue="World") String name, Model model) {
model.addAttribute("name", name);
return "";
}
@RequestMapping(value = "/")
public String welcome() {
System.out.println("welcome page started");
return "redirect:/index.html";
}
@GetMapping(path = "/thankyou")
public String thankyou() {
System.out.println("welcome page started");
return "";
}
}
//完全异常
