java - 从 IncationTargetException 检索 AxisFault 的示例 Java 代码

Question

当 printStackTrace 执行时，我的 InspirationTargetException 打印如下:

AxisFault faultCode: file.could.not.be.created faultSubcode:  faultString: The File could not be created faultActor:  faultNode:  faultDetail:     {http://schemas.xmlsoap.org/soap/envelope/}Fault:file.already.existsFile already existsThe File could not be created    at org.apache.axis.message.SOAPFaultBuilder.createFault(SOAPFaultBuilder.java:222)    at org.apache.axis.message.SOAPFaultBuilder.endElement(SOAPFaultBuilder.java:129)    at org.apache.axis.encoding.DeserializationContext.endElement(DeserializationContext.java:1087)    at org.apache.xerces.parsers.AbstractSAXParser.endElement(Unknown Source)

我想从 InspirationTargetException 中检索错误代码和错误字符串: 文件已存在 文件已存在

我该怎么做？

我不确定为什么堆栈跟踪看起来像这样，并且不包含实际 InvocableFailureException 的痕迹，但我假设 AxisFault 直接包装在 InvocableFailureException 中，然后解开它可能会有所帮助，例如像:

    try {
         // here code which throws InvocationFailureException
    } catch (InvocationFailureException e) {
        Throwable rootCause = e.getRootCause();
        if (rootCause instanceof AxisFault) {
            AxisFault axFault = (AxisFault)rootCause;
            // now extract information, e.g. 
            axFault.getFaultDetails();
        }
    }

如果不直接包装的话，也许您甚至需要递归地获取根本原因。
