wso2ei - 6.1.1 - Axis2Sender在发送消息时出现意外错误
wso2ei - 6.1.1 - Axis2Sender在发送消息时出现意外错误
提问于 2018-05-28 18:05:38
当我试图从wso2ei向我的web服务发送soap请求时，我得到了以下错误：
如果我调用直接代理或web服务，一切都很好，接缝是与发送中介，但我不知道！即使我更改代码以按端点直接调用web服务，错误也是相同的。

我刚发现了一些有趣的行为。如果我用address-endpoint更改wsdl端点，则该API可以工作。我添加了一个payloadFactory来创建一个restResponse和一些日志。
我仍然不知道为什么wsdl端点不能工作，或者我应该修改什么来使它工作。

我想我找到了什么。如果我将address-endpoint直接发送到tomcat的web服务器，如果我通过wso2 2的代理访问我的web服务，那么我可以使用wsdl端点标记作为选择。
我没有任何解释，但这是wso2的行为到目前为止。
