DAOに関するエラーについて

Eclipseにて、「javaアプリケーション」より実行を行なったファイルに、エラーが発生してしまいました。

以下は、MyDataDaoImpl.javaになります。

package com.tuyano.springboot;
import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.criteria.CriteriaBuilder;
import javax.persistence.criteria.CriteriaQuery;
import javax.persistence.criteria.Root;

public class MyDataDaoImpl implements MyDataDao<MyData> {

	private static final long serialVersionUID = 1L;

	@PersistenceContext
	private EntityManager entityManager;

	public MyDataDaoImpl() {
		super();
	}

	public MyDataDaoImpl(EntityManager manager) {

		entityManager = manager;

	}


	@Override
	public List<MyData> getAll(){
		List<MyData> list = null;
		CriteriaBuilder builder = entityManager.getCriteriaBuilder();
		CriteriaQuery<MyData> query = builder.createQuery(MyData.class);
		Root<MyData> root = query.from(MyData.class);
		query.select(root);
		list = (List<MyData>)entityManager.createQuery(query).getResultList();

		return list;

	}

	@Override
	public MyData findById(long id) {
		return (MyData)entityManager.createQuery("from MyData where id = " + id).getSingleResult();

	}

	@Override
	public List<MyData> findByName(String name) {

		return (List<MyData>)entityManager.createQuery("from MyData where nama = " + name).getResultList();

	}

}

以下は、HeloController.javaになります。

package com.tuyano.springboot;
import java.util.Optional;

import javax.annotation.PostConstruct;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;

import org.springframework.web.servlet.ModelAndView;

import com.tuyano.springboot.repositories.MyDataRepository;

@Controller
public class HeloController {

	@Autowired
	MyDataRepository repository;

	@Autowired
	MyDataDaoImpl dao;


	@RequestMapping(value = "/",method = RequestMethod.GET)
	public ModelAndView index(@ModelAttribute("formModel") MyData mydata,ModelAndView mav) {
		mav.setViewName("index");
		mav.addObject("msg","MyDataのサンプルです。");
		Iterable<MyData> list = dao.getAll();
		mav.addObject("datalist",list);
		return mav;
	}
	@RequestMapping(value = "/",method = RequestMethod.POST)
	@Transactional(readOnly=false)
	public ModelAndView form(@ModelAttribute("formModel")@Validated MyData mydata,
			BindingResult result,ModelAndView mov) {
		ModelAndView res = null;
		if(!result.hasErrors()) {
			repository.saveAndFlush(mydata);
			res = new ModelAndView("redirect:/");
		}else {
			mov.setViewName("index");
			mov.addObject("msg","sorry,error is occured...");
			Iterable<MyData> list = repository.findAll();
			mov.addObject("datalist",list);
			res = mov;

		}

		return res;

	}


	@RequestMapping(value = "/edit/{id}", method = RequestMethod.GET)
	public ModelAndView edit(@ModelAttribute MyData mydata, @PathVariable int id, ModelAndView mav) {
		mav.setViewName("edit");
		mav.addObject("title", "edit mydata.");

		System.out.println("ok");
		return mav;

	}




	@RequestMapping(value="/edit",method=RequestMethod.POST)
	@Transactional(readOnly=false)
	public ModelAndView update(@ModelAttribute MyData mydata,ModelAndView mav){

		repository.saveAndFlush(mydata);
		System.out.println(mydata);

		return new ModelAndView("redirect:/");

	}

	@RequestMapping(value = "/delete/{id}",method = RequestMethod.GET)
	public ModelAndView delete(@PathVariable int id,ModelAndView mav) {
		mav.setViewName("delete");
		mav.addObject("title","delete mydata.");
		Optional<MyData> data = repository.findById((long)id);
		System.out.println(data.get());
		mav.addObject("formModel",data.get());
		return mav;
	}

	@RequestMapping(value = "/delete",method = RequestMethod.POST)
	public ModelAndView remove(@RequestParam long id,ModelAndView mav) {
		repository.deleteById(id);
		return new ModelAndView("redirect:/");

	}

	@PostConstruct
	public void init() {

		MyData d1 = new MyData();

		d1.setName("tuyano");
		d1.setAge(123);
		d1.setMail("syoda@tuyano.com");
		d1.setMemo("a");
		repository.saveAndFlush(d1);
		MyData d2 = new MyData();
		d2.setName("hanako");
		d2.setAge(15);
		d2.setMail("hanako@flower");
		d2.setMemo("b");
		repository.saveAndFlush(d2);
		MyData d3 = new MyData();
		d3.setName("sachiko");
		d3.setAge(37);
		d3.setMail("sachico@happy");
		d3.setMemo("c");
		repository.saveAndFlush(d3);

	}

}

class DataObject{

	private int id;
	private String name;
	private String value;

	public DataObject(int id, String name, String value){

		super();
		this.id = id;
		this.name = name;
		this.value = value;
	}

	public int getId(){ return id;}
	public void setId(int id){ this.id = id;}
	public String getName() { return name;}
	public void setName(String name){

		this.name = name;

	}

	public String getValue(){

		return value;

	}

	public void setValue(String value){

		this.value = value;

	}




}

以下はMyData.javaです

package com.tuyano.springboot;

import java.io.Serializable;
import java.util.List;

public interface MyDataDao<T> extends Serializable {

	public List<T> getAll();
	public T findById(long id);
	public List<T> findByName(String name);

}

以下はエラー内容となります。
