Spring JPA（Hibernate）タイプの修飾Beanはありません：javax.persistence.EntityManagerFactory
私はSpring-bootを使用しているため、Tomcat 7で戦争が展開されました。アプリを起動すると、次のメッセージが表示されます。

これが私のアプリケーションの起動方法です：
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Springコントローラーが接続を処理するとき：
@Controller
public class GetController {
private UserService userService;
@Autowired
public void setUserService(UserService userService) {
this.userService = userService;
}
@RequestMapping(value = "/user", method = RequestMethod.GET)
public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {
User user = null;
user = userService.getUser(id);
return user;
}
}
UserServiceでgetUserを実行します。
@Component
public class UserService {
private UserDAO UserDao;
public UserDAO getUserDao() {
return UserDao;
}
@Autowired
public void setUserDao(UserDAO UserDao) {
this.UserDao = UserDao;
}
public User getUser(int id) {
return getUserDao().load(id);
}
}
UserDaoを使用してエンティティを見つけます：
@Repository("userDao")
@Transactional(propagation=Propagation.REQUIRED)
public class UserDAO {
@PersistenceContext
private EntityManager entityManager;
public void insert(User user) {
entityManager.persist(user);
}
public User load(int id) {
return entityManager.find(User.class, id);
}
}
/ src/main/resourcesに次のspring-config.xmlがあります。
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

<property name="url" value="jdbc:postgresql://localhost:5432/mydb" />
<property name="username" value="my_user" />
<property name="password" value="" />
</bean>
</beans>
そして最後になりましたが、次の/src/main/resources/persistence.xml：
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://Java.Sun.com/xml/ns/persistence"
version="1.0">
<persistence-unit name="userPersistenceUnit" transaction-type="RESOURCE_LOCAL" >
<class>com.mydomain.orm.User</class>
</persistence-unit>
</persistence>
このエラーを解決するには何をする必要がありますか？
EntityManagerをインジェクトしたいのですが、フィールドにインジェクションアノテーションがなく、「factory」はどのような場合でも間違った修飾子です。複数の永続性ユニットを区別する必要がある場合は、unitNameを使用して、フィールドに@PersistenceContext注釈を付けます。
編集された質問への回答： XMLファイルは含まれません。これは、Applicationクラスから開始し、Springはそこから@ComponentScanに従うだけだからです。このインポートをApplicationクラス（またはスキャンされた@Configurationクラス）に追加します。
@ImportResource("classpath:spring-config.xml")
または、XML構成をJavaConfig形式に移行して、Springでコンポーネントをスキャンすることもできます。
あなたの問題は、すでにアノテーション付きのBeanのクラスパスを検索するアノテーション構成を使用していることです。これにより、UserDAOのインスタンス化が試行されますが、ここではEntityManagerFactoryを提供しません。
@ImportResource("classpath:spring-config.xml")を介して、JavaConfigをXML構成と組み合わせることができます。
@Configuration
@ComponentScan
@EnableAutoConfiguration
@ImportResource("classpath:spring-config.xml")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
@Controller
public class GetController {
@Autowired
UserService userService;
@RequestMapping(value = "/user", method = RequestMethod.GET)
public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {
return userService.getUser(id);
}
}
@Component
public class UserService {
@Autowired
private UserDAO UserDao;
public User getUser(int id) {
return getUserDao().load(id);
}
}
DAOに SpringData を使用することをお勧めします。多くの定型コードを節約できます。
クラッシュから出たautoconfigレポートを見ると、DataSourceが定義されていないことがわかります。クラスパスに適切なものがある場合は、Spring Bootが作成します。たとえば、少なくとも、クラスパスにh2またはhsqldbが含まれている場合、機能します。
ちなみに、Spring Bootを正しい方法で使用すると、XMLファイルは冗長になります。
