Spring + toplink-essentials(JPA) is not a known entity type 问题解决

在我本地的是这样的代码：
<property name="loadTimeWeaver">    <bean class="com.ctit.tools.MyLoadTimeWeaver"/></property>public class MyLoadTimeWeaver extends SimpleLoadTimeWeaver {?@Override?public ClassLoader getInstrumentableClassLoader() {????     return super.getInstrumentableClassLoader().getParent();?}}
