Question

我有一个使用Eclipselink 2.5的应用程序，在运行Junit测试用例时，我总是收到此警告：

[EL Warning]: metadata: 2013-08-19 01:14:05.142--ServerSession(14351551)--
Reverting the lazy setting on the OneToOne or ManyToOne attribute [currentTransit]
for the entity class [class ......persistent.entity.BPExecutionEntity] since
weaving was not enabled or did not occur.

所以，我在我的Ant构建文件上写了一个'编织'任务，如下所示：

<target name="define.task" description="New task definition for EclipseLink static weaving">
    <taskdef name="weave" classname="org.eclipse.persistence.tools.weaving.jpa.StaticWeaveAntTask"/>
</target>
<target name="weaving" description="perform weaving" depends="define.task">
    <weave  source="D:\...\dist\${ant.project.name}.jar"
            target="D:\...\dist\woven-${ant.project.name}.jar"
            persistenceinfo="D:\...\lib\persistence.jar">
        <classpath>
        </classpath>
    </weave>
</target>

好的，一切正常，当我编译代码时，它会生成一个编织文件大小一半的编织文件。但是，当我运行项目的测试时，我仍然收到相同的警告blah blah blah... since weaving was not enabled or did not occur.

有人知道如何从我的测试中删除此警告吗？

Answer 1

您需要指定在persistence.xml属性中使用静态编织。看到 http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Performance/Weaving/Static_Weaving

“步骤2：配置persitence.xml”了解详细信息

Answer 2

我终于用动态编织解决了这个问题。当我使用Netbeans 7.3.1时，我转到Project Options | Run | VM options并添加了此文本：-javaagent:C:\eclipselink\jlib\eclipselink.jar，您可以将地址更改为您在eclipselink.jar中找到的任何地址。

然后我将此行添加到persistence.xml：

<property name="eclipselink.weaving" value="true"/>

这就是全部。此配置使动态编织能够执行测试用例并删除[EL Warning] Reverting the lazy setting on the OneToOne or ManyToOne attribute...etc.

JPA - 运行测试用例时未启用编织
