如下所示，在weblogic.xml中添加容器描述符后，问题将解决。

<wls:container-descriptor>
<wls:prefer-web-inf-classes>true</wls:prefer-web-inf-classes>
</wls:container-descriptor>
 <wls:session-descriptor>
    <wls:timeout-secs>900</wls:timeout-secs>
    <wls:persistent-store-type>replicated_if_clustered</wls:persistent-store-type>
</wls:session-descriptor>
