我正在使用Mule架构验证过滤器来针对给定方案验证传入的
XML文件.以下是我对架构组件的配置：
< mulexml：schema-validation-filter schemaLocations =“${app.home} /classes/schemas/Library.xsd”doc：name =“Schema Validation”/>
我遇到的问题是,当文件无法对模式进行验证时,Mule会静默阻止消息继续 – 即不会抛出错误/异常.通过一些实验,我发现如果我将以下内容添加到log4j.properties文件中,我可以在架构验证中看到“错误”：
log4j.logger.org.mule.module.xml.filters.SchemaValidationFilter = DEBUG
由于这些错误是’DEBUG’级别日志并且没有抛出实际异常,因此我的流程不会恢复为我配置的异常策略.
所以我的问题是……
如果模式验证中存在错误,我可以在这里做些什么来使Mule恢复为异常策略吗？我在文件无法验证时看到的调试日志下面有一份副本.提前致谢.

UPDATE
根据@RyanCarter(有效)提供的答案,我还发现以下解决方案在Mule Studio中没有任何错误.它涉及全局定义模式验证过滤器并在消息过滤器中引用它,如下所示：
<mulexml:schema-validation-filter name="myValidator".../>
<flow>
<message-filter throwOnUnaccepted="true">
<filter ref="myValidator"/>
</message-filter>
您可以将schema-validation-filter包装在消息过滤器中,并将throwOnUnaccepted设置为“true”：
<message-filter throwOnUnaccepted="true"> <mulexml:schema-validation-filter... /> </message-filter>
然后,您可以使用异常策略来处理异常.
