applicationContext.xml 파일 내에서 persistence.xml을 가져올 수 없습니다.

이클립스 주노 IDE를 사용하고 있습니다. src 폴더가있는 Java 응용 프로그램이 있습니다. 내 폴더 안에 :

1) applicationContext.xml

2) persistence.xml

나는 또한 DBInterface를 가지고 JPA로 구현했다. 이제 applicationContext.xml 파일에 JPA 구현을위한 bean이있다.

내가 빈을 주입하려고했을 때 "아무런 지속성 제공자도 발견되지 않았다"는 예외를 얻었다.

그래서 applicationContext 파일 내에서 퍼시스턴스 파일을 가져 오려고했지만 또 다른 예외가 생깁니다.

해결법

==============================
1.persistence.xml을 Spring 구성으로 사용하려는 시도는 절대적으로 의미가 없습니다. 왜냐하면 persistence.xml은 Spring 구성이 아니기 때문입니다.

persistence.xml을 Spring 구성으로 사용하려는 시도는 절대적으로 의미가 없습니다. 왜냐하면 persistence.xml은 Spring 구성이 아니기 때문입니다.

Spring에서 JPA를 사용하려면 persistence.xml을 소스 폴더의 META-INF 폴더에 넣고 applicationContext.xml에 LocalContainerEntityManagerFactory를 선언해야합니다.
```
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name = "persistenceUnitName" value = "MyJPA" />
</bean>
```
@PersistenceContext를 사용하여 Spring 빈에 EntityManager를 삽입 할 수있다.
```
@PersistenceContext
private EntityManager em;
```
참조 :
==============================
2.다음과 같이 가져와야합니다.

다음과 같이 가져와야합니다.
```
<import resource="classpath:META-INF/persistence.xml"/>
```
persistence.xml이 classpath에있는 jar 중 하나의 최상위 디렉토리 인 META-INF 디렉토리에 있다고 가정합니다.
==============================
3.좋아, 나는 이것을 해결했다 ..

좋아, 나는 이것을 해결했다 ..

내가 한 것은 persistence.xml 파일을 META-INF 폴더에 넣는 것입니다. vikdor와 axtavt가 제안했다. 하지만 응용 프로그램 컨텍스트에서 나는 어떤 파일도 가져 오지 않았다. 방금이 편지를 썼다.
```
<bean id="JPA" class="pack.jpa.JPAQueries"/>
```
그리고 그 일!
