Tomcat 7 Frühling 3.1 Eclipselink 2.3

Ich versuche meine erste Feder-Anwendung zu entwickeln und es zu Tomcat 7 zu implementieren. Ich erstellte die Projektkonfiguration und alles funktionierte gut. Ich hatte ein Problem, als ich einen Onetoone Field Fetch Modus zu LAZY änderte.Tomcat 7 Frühling 3.1 Eclipselink 2.3

Ich denke, das Problem ist mit der Ladezeit-Weberei

folgenden sind die Konfiguration:

<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 />

und ich fügte folgendes META-INF/context.xml

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

HINWEIS: Ich verwende eine polymorphe Abfrage (eine übergeordnete Entität Klasse abfragt)

jemand mich in die richtige Richtung zeigen kann meine App konfigurieren um die Einheitenklassen richtig zu weben?

HINWEIS: Ich habe die gleiche Abfrage auf Glassfish (mit EJB Sessionfacade) getestet und es funktioniert gut.

Eigentlich war der Fehler mit Tomcat Version, ich wurde mit Tomcat 7.0.22 und der Fehler wird mit der Version 7.0.26 fixiert, so Upgrade Tomcatbediener das Problem gelöst.

Der Fehler bedeutet, dass das Weben nicht aufgetreten ist. Sie haben Spring also nicht richtig konfiguriert.

Wenn Sie die Protokollierung am feinsten einstellen, können Sie sehen, ob EclipseLink Weben ausführt.

Ich sehe nichts falsch in Ihren Konfigurationsdateien, was passiert, wenn Sie den TomcatInstrumentableClassLoader nicht hinzufügen?

Es kann sein, dass Sie auf Ihre Klassen zugreifen, bevor Sie auf Ihren Spring-Kontext zugreifen. Wenn Sie dies tun, werden die Klassen bereits geladen, bevor Spring die Möglichkeit hat, sie zu instrumentieren.

Wenn Sie nicht dynamisch Weben Arbeit bekommen können, können Sie statische Weben oder deaktivieren Weben verwenden.

Aber wie kann ich das akivieren? Welche Änderungen muss ich an den Konfigurationen vornehmen? –
