Lỗi khi run project spring boot

Bạn đưa code DAO và Controller xem
Mà code không có tầng Service control business layer à?

Gợi ý:

• class implement DAO interface có annotation @Repository chưa?
• Bạn thử @Autowired DAO interface thay vì class implement xem
• Nếu không được nữa thì tạo contructor cho controller, truyền class implement xem
• Nhớ chỉnh sửa code xong gõ mvn clean package để rebuild lại app. Chạy file jar java -jar <đường dẫn file jar> thay vì mvn spring-boot:run

Controller
    package com.itsol.controller;

import java.util.Optional;

import javax.validation.Valid;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import Dao.CategoryDaoImp;
import Model.Category;

@RestController
@RequestMapping("/category")
public class CategoryController {
	@Autowired
	private CategoryDaoImp categoryDaoimp;
	@GetMapping("/category")
	public Page<Category> getCategory(Pageable pageable){
		return categoryDaoimp.findAll(pageable);
	}
	@PostMapping("/category")
	public Category createCategory(@Valid @RequestBody Category category) {
		return categoryDaoimp.save(category);
	}
	@PutMapping("/category/{categoryId}")
	public Optional<Category> updateCategory(@PathVariable Long categoryId,@Valid @RequestBody Category categoryRequest)
	{
	return categoryDaoimp.findById(categoryId).map(category->{category.setName(categoryRequest.getName());
	return categoryDaoimp.save(category);});
	}
	@DeleteMapping("/category/{categoryId}")
	public Optional<?> deleteCategory(@PathVariable Long categoryId){
		return categoryDaoimp.findById(categoryId).map(category->{categoryDaoimp.delete(category);
		return ResponseEntity.ok().build();});
	}
}

em để cả @reponsitory với @autuwired cả rồi mà lúc chạy không được ạ
