Question

我正在使用Hibernate JPA / spring开展一个项目。

它抛出以下异常。在做了一些阅读之后，我从依赖项中删除了所有xml-apis，但是它会抛出相同的错误。任何想法??

当我试图在jetty web服务器中初始化web上下文时，它抛出了上述异常。[Spring（3.0.6.Release）＆amp; hibernate（4.1.10.final）]

删除loadtimeweaver属性后，它工作正常。

<property name="loadTimeWeaver"> <bean class="org.faces.controller.jpa.JpaLoadTimeWeaver"/> </property>

这是一个链接，表明虽然它已经很老了但它可以运作
