SoapUI5.7 + Mule4.4：“java.lang.IllegalArgumentException：路径参数必须以/开头”

Question

我正在使用 SoapUI 检查 Mule 并遇到问题 path parameter must start with /。

Mule 上的错误消息

步骤

1. 在此处查找 WSDL (https://www.dataaccess.com/webservicesserver/numberconversion.wso?WSDL)

2. [Mule4.4] 创建监听器和 SOAP 路由器。
   HTTP 侦听器配置：端口 = 1081
   SOAP 配置：Wsdl 位置 =（步骤 1 中的 URL。）

1. [SoapUI5.7] 使用步骤 1 中的 URL 创建一个新的 SOAP API。然后创建一个新请求 (https://0.0.0.0:1081/NumberConversion/NumberConversionSoap) 并运行它。底部的消息说“未能响应”

2. [Mule4.4] 查看消息。

备注

我确认 Listener's Path 以“/”开头。

Answer 1

这是一个警告而不是错误。它很可能是无害的。确保您使用的是最新版本的 Studio 和 Mule 4.4 的累积补丁。但是日志中有一些奇怪的东西。它看起来正在为 Mule 4.3 (mule-service-http-1.6.3) 执行 HTTP 服务，这不是 Mule 4 的正确版本。可能是该项目正在 Mule 4.3 中执行？检查应用程序启动时的日志并确定运行配置。
