druid的WallFilter问题?报错

@wenshao 你好，想跟你请教个问题：

我配置打开了wallconfig的配置：

<bean id="wall-filter-config" class="com.alibaba.druid.wall.WallConfig" init-method="init">
	      <!-- 指定配置装载的目录  -->
	      <property name="dir" value="META-INF/druid/wall/oracle" />
	      <property name="deleteWhereAlwayTrueCheck" value="false"/>
	      <property name="updateWhereAlayTrueCheck" value="false"/>
	      <property name="objectCheck" value="false"/>
	      <property name="variantCheck" value="false"/>
	      <property name="functionCheck" value="false"/>
	      <property name="commentAllow" value="true"/>
	      <property name="multiStatementAllow" value="true"/>
	      <property name="truncateAllow" value="true"/>
	      <property name="selectUnionCheck" value="false"/>	  
	      <property name="alterTableAllow" value="true"/>
	      <property name="noneBaseStatementAllow" value="true"/>
	      <property name="schemaCheck" value="false"/>
	      <property name="dropTableAllow" value="true"/>
	  </bean>

在执行关闭外键的时候报错：
