Springブート - beanという名前のentityManagerFactory

Question

jHipsterで生成された簡単なSpringブートアプリケーションをpostgresqlから取得し、postreSQLデータベースの記事のリストを表示し、残りのコントローラを使用して表示するようにしようとしていますが、

*************************** 
APPLICATION FAILED TO START

Description: 

Parameter 0 of constructor in org.adi.security.DomainUserDetailsService required a bean named 'entityManagerFactory' that could not be found. 


Action: 

Consider defining a bean named 'entityManagerFactory' in your configuration. 

しかし、事は `DomainUserDetailsS​​erviceは私が私のクラスを追加した後に動作を停止jhipsterによって生成された何かであることということです。だから私は私のクラスの下に書きます：

条エンティティ：

package org.adi.domain; 

import java.io.Serializable; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name="articles") 
public class Article implements Serializable { 
    private static final long serialVersionUID = 1L; 
    @Id 
    @GeneratedValue(strategy=GenerationType.AUTO) 
    @Column(name="article_id") 
    private int articleId; 
    @Column(name="title") 
    private String title; 
    @Column(name="category") 
    private String category; 
    public int getArticleId() { 
     return articleId; 
    } 
    public void setArticleId(int articleId) { 
     this.articleId = articleId; 
    } 
    public String getTitle() { 
     return title; 
    } 
    public void setTitle(String title) { 
     this.title = title; 
    } 
    public String getCategory() { 
     return category; 
    } 
    public void setCategory(String category) { 
     this.category = category; 
    } 
} 

ArticleDAO（リポジトリ）：

@Transactional 
@Repository 
public class ArticleDAO implements IArticleDAO { 
    @PersistenceContext 
    private EntityManager entityManager; 
    @Override 
    public Article getArticleById(int articleId) { 
     return entityManager.find(Article.class, articleId); 
    } 
    @SuppressWarnings("unchecked") 
    @Override 
    public List<Article> getAllArticles() { 
     String hql = "FROM Article as atcl ORDER BY atcl.articleId DESC"; 
     return (List<Article>) entityManager.createQuery(hql).getResultList(); 
    } 
    @Override 
    public void createArticle(Article article) { 
     entityManager.persist(article); 
    } 
    @Override 
    public void updateArticle(Article article) { 
     Article artcl = getArticleById(article.getArticleId()); 
     artcl.setTitle(article.getTitle()); 
     artcl.setCategory(article.getCategory()); 
     entityManager.flush(); 
    } 
    @Override 
    public void deleteArticle(int articleId) { 
     entityManager.remove(getArticleById(articleId)); 
    } 
    @Override 
    public boolean articleExists(String title, String category) { 
     String hql = "FROM Article as atcl WHERE atcl.title = ? and atcl.category = ?"; 
     int count = entityManager.createQuery(hql).setParameter(1, title) 
      .setParameter(2, category).getResultList().size(); 
     return count > 0 ? true : false; 
    } 
} 

ArticleService：

@Service 
public class ArticleService implements IArticleService { 
    @Autowired 
    private IArticleDAO articleDAO; 
    @Override 
    public Article getArticleById(int articleId) { 
     Article obj = articleDAO.getArticleById(articleId); 
     return obj; 
    } 
    @Override 
    public List<Article> getAllArticles(){ 
     return articleDAO.getAllArticles(); 
    } 
    @Override 
    public synchronized boolean createArticle(Article article){ 
     if (articleDAO.articleExists(article.getTitle(), article.getCategory())) { 
      return false; 
     } else { 
      articleDAO.createArticle(article); 
      return true; 
     } 
    } 
    @Override 
    public void updateArticle(Article article) { 
     articleDAO.updateArticle(article); 
    } 
    @Override 
    public void deleteArticle(int articleId) { 
     articleDAO.deleteArticle(articleId); 
    } 
} 

、最終的に私のRESTコントローラ：

@Controller 
@RequestMapping("user") 
@CrossOrigin(origins = {"http://localhost:4200"}) 
public class ArticleController { 
    @Autowired 
    private IArticleService articleService; 
    @GetMapping("article") 
    public ResponseEntity<Article> getArticleById(@RequestParam("id") String id) { 
     Article article = articleService.getArticleById(Integer.parseInt(id)); 
     return new ResponseEntity<Article>(article, HttpStatus.OK); 
    } 
    @GetMapping("all-articles") 
    public ResponseEntity<List<Article>> getAllArticles() { 
     List<Article> list = articleService.getAllArticles(); 
     return new ResponseEntity<List<Article>>(list, HttpStatus.OK); 
    } 
    @PostMapping("article") 
    public ResponseEntity<Void> createArticle(@RequestBody Article article, UriComponentsBuilder builder) { 
     boolean flag = articleService.createArticle(article); 
     if (flag == false) { 
      return new ResponseEntity<Void>(HttpStatus.CONFLICT); 
     } 
     HttpHeaders headers = new HttpHeaders(); 
     headers.setLocation(builder.path("/article?id={id}").buildAndExpand(article.getArticleId()).toUri()); 
     return new ResponseEntity<Void>(headers, HttpStatus.CREATED); 
    } 
    @PutMapping("article") 
    public ResponseEntity<Article> updateArticle(@RequestBody Article article) { 
     articleService.updateArticle(article); 
     return new ResponseEntity<Article>(article, HttpStatus.OK); 
    } 
    @DeleteMapping("article") 
    public ResponseEntity<Void> deleteArticle(@RequestParam("id") String id) { 
     articleService.deleteArticle(Integer.parseInt(id)); 
     return new ResponseEntity<Void>(HttpStatus.NO_CONTENT); 
    } 
}

パーシスタンスユニットを作成しましたか？

[参考] =>https://docs.oracle.com/cd/E19798-01/821-1841/bnbrj/index.html

あなたはすでにあなたはこのようなあなたのエンティティマネージャを作成することができます永続性ユニットのタグが定義されていたら：

private final String PERSISTENCE_UNIT_NAME = "PUName"; 
private EntityManagerFactory eMFactory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME); 
EntityManager entityManager=eMFactory.createEntityManager();
