我正在研究基于 SOAP 的 Web 服务。我需要测试一个场景，如果由于任何网络问题或登录问题而发生 Web 服务连接错误。
apache cxf 的问题在于无论 web 服务抛出什么异常
"java.lang.UnsupportedOperationException: This class does not support SAAJ 1.1".
错误响应代码返回 500，但堆栈跟踪显示“UnsupportedOperationException”。我可以捕获异常并打印堆栈跟踪，但我需要知道它是连接错误还是其他一些不同的错误。错误日志如下

有人可以指导我或帮助我如何在 try catch 块中捕获此特定连接错误或错误 500。
