Spring Web Services - 异常跳过ExceptionResolver

Question

我有一个SOAP服务,如果我为XML元素指定了错误的输入,请求和响应按预期工作,输入良好

在请求正文中:

...
<ns:myIntegerElement>asdf</ns:myIntegerElement>
...

我的异常解析器被调用,这个解析器只是异常解析器的一个实现,因此它没有异常映射,只是抽象方法中的一些System.out

<bean id="exceptionResolver" class="com.mycompany.ws.MyExceptionResolver">

但是,如果我发送的请求看起来更像这样:

...
    <ns:myIntegSOMETHINGGOTTOTALLYMESSUP!!!ent>asdf</ns:myIntegerElement>
...

我的解析器根本没有执行

我将log4j设置为具有根调试级别并查看此输出:

看来spring在这里缺少一个可能的异常,并没有包装它,但是这样一个基本的错误条件没有被捕获似乎不太可能.任何人都可以帮我找到这个问题的根源吗？

我也将包含web.xml和servlet.xml:

web.xml中:

    </bean>

Answer 1

MessageDispatcherServlet默认创建自己的两个EnpointExceptionResolver实例,即SoapFaultAnnotationExceptionResolver @ 1和SimpleSoapExceptionResolver @ 2

当它解决异常时,SimpleSoapExceptionResolver @ 2将停止任何其他已注册的EnpointExceptionResolver来处理异常.

我花了很长时间才弄清楚,但答案很简单,在你的servlet上下文中你必须这样做:

<bean id="exceptionResolver" class="com.wdp.smm.ws.MyExceptionResolver">
    <property name="order" value="1"/>
</bean>

Answer 2

我更仔细地看了你的问题，我想我知道发生了什么。不会调用您的异常处理程序，因为它在soap 处理中处于较高级别。您会看到，WebServiceMessageReceiverHandlerAdapter 尝试将传入的字符串解码为 XML，然后再将其发送到编组器进行处理。由于 XML 无效，调用失败。由于 WebServiceMessageReceiverHandlerAdapter 不支持异常处理程序，它只是重新抛出异常“SaajSoapMessageException”。

现在您可以做的是创建一个扩展 WebServiceMessageReceiverHandlerAdapter 的新类，但它也将 handleConnection() 包装在 try/catch 中，该类在抛出异常时使用您的异常处理程序。

顺便说一下，在调试此类问题时，我的方法是在 log4j 中输出方法名称和行号。以及下载Spring源。
