tomcat 7 Spring 3.1 Eclipselink 2.3

我正在嘗試開發我的第一個spring應用程序並將它部署到tomcat 7.我創建了項目配置，並且每件事情都很好。當我將onetoone字段獲取模式更改爲LAZY時，我遇到了問題。tomcat 7 Spring 3.1 Eclipselink 2.3

我認爲這個問題是與裝載時編織

以下是配置：

<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 />

和添加以下到META-INF/context.xml的

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

以下錯誤是在第一次請求中提出的：

注：我使用的是多態查詢（查詢父實體類）

任何人都可以點我朝着正確的方向來配置我的應用程序向右編織實體類？

注：我在glassfish上測試了相同的查詢（使用EJB sessionfacade），它工作正常。

其實問題出在Tomcat版本上，我使用的是Tomcat 7.0.22，錯誤是使用7.0.26版本修復的，所以升級tomcat服務器解決了這個問題。

錯誤意味着編織沒有發生。所以，你沒有正確配置Spring。

如果您設置最好的日誌記錄，您可以看到EclipseLink是否執行任何編織。

我在配置文件中看不到任何錯誤，如果不添加TomcatInstrumentableClassLoader，會發生什麼情況？

在訪問Spring上下文之前，可能會訪問您的類。如果你這樣做，那麼在Spring有機會測試它們之前，這些類將已經被加載。

如果無法使動態織入工作，則可以使用靜態編織或禁用編織。

但是，我該如何行事呢？我必須對配置做出什麼改變？ – 2012-03-28 19:02:58
