weblogic + spring + eclipselink의 JNDI 문제

Question

Spring 3.0에서 지속성 공급자로 eclipselink를 사용하는 애플리케이션이 있습니다. 응용 프로그램이 Jetty 응용 프로그램 서버에서 제대로 작동하지만 웹 로직에 배포 할 때 오류가 발생합니다. 내가 web.xml에 태그를 선언 한

  jdbc.driverClassName=org.postgresql.Driver 
     jdbc.url=jdbc:postgresql://localhost:5432/myDB 
     jdbc.username=*** 
     jdbc.password=*** 

     jndi.name=jndi/myDBjndi 
     jndi.resourceRef=true 
      jndi.enabled=true 

     hibernate.database.platform=org.hibernate.dialect.PostgreSQLDialect 
    toplink.database.platform=org.eclipse.persistence.platform.database.PostgreSQLPlatform  

다음과 같이이 켜지지 세부

봄 XML 파일

<context:property-placeholder location="classpath:jdbc.properties" 
    ignore-unresolvable="true" /> 
    <jee:jndi-lookup id="jndiDataSource" jndi-name="${jndi.name}" 
    resource-ref="true" /> 

<bean id="pum" 
    class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager"> 
    <property name="persistenceXmlLocations"> 
     <list> 
      <value>classpath*:META-INF/persistence.xml</value> 
     </list> 
    </property> 
    <property name="defaultDataSource" ref="jndiDataSource" /> 
</bean> 
     <bean id="entityManagerFactory" 
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="persistenceUnitName" value="my-persistence" /> 
    <property name="persistenceUnitManager" ref="pum" /> 
    <property name="jpaDialect" ref="jpaDialect" /> 
    <property name="jpaVendorAdapter" ref="jpaAdapter" /> 
    <property name="loadTimeWeaver" ref="loadTimeWeaver" /> 
</bean> 

<bean id="jpaAdapter" 
    class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter" 
    p:databasePlatform="${toplink.database.platform}" p:showSql="true" /> 

<bean id="jpaDialect" 
    class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" /> 

특성 파일 이하이다

  <resource-ref> 
    <descriptionMy DataSource Reference</description> 
    <res-ref-name>jndi/myDBjndi</res-ref-name> 
    <res-type>javax.sql.DataSource</res-type> 
    <res-auth>Container</res-auth> 
</resource-ref>  

위의 작품 Jetty에서 Weblogic 10.3.4에서 예외가 발생했습니다

무엇이 잘못 되었습니까?

Answer 1

그것은 왜냐하면 weblogicpersistence.xml 파일이 /META-INF 폴더에 할당를 자동으로 감지하고 미리로드 Persistence Unit 같은 자바 EE 컨테이너 (사용하여 구현 내장)하지만, 최대 절전 수준에서 설정 한 JPA 속성의 단서가 없습니다. 퍼시스턴스 유닛은 Spring으로 부트 스트래핑해야하므로 파일 이름을 다른 것으로 변경하면 문제가 해결됩니다.
