[英]Consider defining a bean of type 'package' in your configuration
我正在尝试在Spring Boot中创建一个简单的REST服务。 在使用CrudRepository之前,一切工作正常。 现在我得到这个错误-
***申请未能开始
描述:
company.springBoot.io.Employee.EmployeeService中的字段er需要一个类型为'company.springBoot.io.Employee.EmployeeRepo'的bean。
行动:
考虑在您的配置中定义类型为'company.springBoot.io.Employee.EmployeeRepo'的bean。***
这是我的代码-
控制器-
@RestController
public class EmployeeController {
@Autowired
EmployeeService employeeService;
@GetMapping("/employees")
public List<Employee> getAllEmployees(){
return employeeService.getAllEmployees();
}
@GetMapping("/employees/{id}")
public Employee getEmployee(@PathVariable int id) {
return employeeService.getEmployee(id);
}
@PostMapping("/employees")
public String addEmployee(@RequestBody Employee e) {
employeeService.addEmployee(e );
return "Employee Records were added successfully";
}
@PutMapping("/employees/{id}")
public String updateEmployee(@RequestBody Employee e, @PathVariable int id) {
return employeeService.updateEmployee(e, id);
}
@DeleteMapping("/employees/{id}")
public @ResponseBody String deleteEmployee(@PathVariable int id) {
return employeeService.deleteEmployee(id);
}
}
服务-
@Autowired
EmployeeRepo er;
public List<Employee> getAllEmployees() {
List<Employee> list= new ArrayList<>();
er.findAll()
.forEach(list::add);
return list;
//return list;
}
public void addEmployee(Employee e) {
// TODO Auto-generated method stub
er.save(e);
}
public String updateEmployee(Employee e, int id) {
// TODO Auto-generated method stub
er.save(e);
String s= "The Employee with id has been replaced by Employee with id "+e.getId();
return s;
}
public String deleteEmployee(int id) {
// Auto-generated method stub
er.deleteById(id);
return "Employee withh id "+id+" has been removed from the company";
}
public Employee getEmployee(int id) {
return er.findById(id).get();
}
}
CrudRepository的接口
package company.springBoot.io.Employee;
import org.springframework.data.repository.CrudRepository;
public interface EmployeeRepo extends CrudRepository<Employee, Integer>{
}
根
package company.springBoot.io.EmployeeRest;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication(scanBasePackages=
{"company.springBoot.io.Employee"})
public class EmployeeRestApplication {
public static void main(String[] args) {
SpringApplication.run(EmployeeRestApplication.class, args);
}
}
有人可以帮我弄这个吗?
-------------------------------------- 更新 ----------- ---------------------------我这样更改了文件夹结构-
现在我得到这个错误-
您缺少注释
package company.springBoot.io.Employee;
import org.springframework.data.repository.CrudRepository;
@Repository /// here is the trick
public interface EmployeeRepo extends CrudRepository<Employee, Integer>{
}
由于缺少注释,Spring没有扫描该接口,因此无法创建此类依赖项。
