我尝试将spring与eclipseLink一起使用,并且我遇到了IntegrityException。 这是我的配置:

完全例外是:

但是当我使用其他供应商时我没有这个问题
org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter
任何想法?

尝试使用此loadtimeweaver实现:
package net.palesz.util;
import org.springframework.instrument.classloading.SimpleLoadTimeWeaver;
public class JpaAwareLoadTimeWeaver extends SimpleLoadTimeWeaver {
@Override
public ClassLoader getInstrumentableClassLoader() {
ClassLoader instrumentableClassLoader = super.getInstrumentableClassLoader();
if (instrumentableClassLoader.getClass().getName().endsWith("SimpleInstrumentableClassLoader")) {
return instrumentableClassLoader.getParent();
} else {
return instrumentableClassLoader;
}
}
}
Spring context.xml config:
<bean id="loadTimeWeaver" class="net.palesz.util.JpaAwareLoadTimeWeaver" />

奇怪的错误,因为IndirectSet有效。它似乎是一个类加载器问题,但我之前没有在Spring中看到它。
它可能与您使用loadTimeWeaver有关,因此您可以尝试删除它。
你在什么环境下运行Spring?

你必须使用代理进行动态编织
-javaagent:弹簧剂2.5.6.jar
我曾尝试过eclipseLink代理,但它没有用。
