tomcat 7 Spring 3.1 Eclipselink 2.3

Я пытаюсь развернуть свое первое приложение весны и развернуть его на tomcat 7. Я создал конфигурацию проекта, и все отлично работало. Я столкнулся с проблемой, когда я изменил режим onetoone field fetch на LAZY.tomcat 7 Spring 3.1 Eclipselink 2.3

Я думаю, что проблема с грузоподъемным временем ткачества

следующие конфигурации:

<bean id="scholarDataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close"> 
    ... 
</bean> 

<bean id="scholarEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="dataSource" ref="scholarDataSource" /> 
    <property name="packagesToScan" value="edu.najah.scholar.spring.entities" /> 
    <property name="jpaVendorAdapter"> 
     <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> 
      <property name="showSql" value="true"/> 
      <property name="generateDdl" value="true"/> 
      <property name="databasePlatform" value="org.eclipse.persistence.platform.database.oracle.Oracle11Platform"/> 
     </bean> 
    </property> 
    <property name="jpaDialect"> 
     <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" /> 
    </property>   
    <property name="loadTimeWeaver"> 
     <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" /> 
    </property> 
</bean> 


<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="scholarEmf" /> 
</bean> 

<tx:annotation-driven transaction-manager="txManager"/> 
<context:component-scan base-package="edu.najah.scholar.spring" /> 
<context:load-time-weaver />

и я добавил следующий META-INF/context.xml

<Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>

Примечание: Я использую полиморфной запрос (запрашивая родительский класс сущностей)

кто может мне точку в правильном направлении, чтобы настроить мое приложение для правильного ткачества классов сущностей?

ПРИМЕЧАНИЕ: Я тестировал тот же запрос на стеклянную рыбку (используя EJB sessionfacade), и он отлично работает.

На самом деле ошибка была с версией Tomcat, я использовал Tomcat 7.0.22, и исправлена ошибка с версией 7.0.26, поэтому обновление сервера tomcat решило проблему.

Ошибка означает, что ткачество не произошло. Таким образом, вы не настроили Spring правильно.

Если вы установили рекорд, вы можете увидеть, работает ли EclipseLink какое-либо плетение.

Я не вижу ничего плохого в ваших конфигурационных файлах, что произойдет, если вы не добавите TomcatInstrumentableClassLoader?

Возможно, вы получаете доступ к своим классам до того, как получите доступ к контексту Spring. Если вы сделаете это, классы будут уже загружены до того, как весна сможет их обработать.

Если вы не можете заставить динамическое ткачество работать, вы можете использовать статическое ткачество или отключить ткачество.

Но как я могу это воспринять? Какие изменения я должен внести в конфигурации? –
