我创建了以下WSO2数据服务器服务。

我想通过wso2 ESB使用此服务。但是我无法让它发挥作用。我应该如何在ESB中公开服务以及我应该应用哪种类型的安全性？你能给我一些参考指南吗？
我尝试了以下ESB配置：
<proxy name="Codelists" transports="https" startOnLoad="true" trace="disable">
<target>
<endpoint>
<address uri="http://localhost:9446/services/Codelists"/>
</endpoint>
<outSequence>
<send/>
</outSequence>
</target>
<publishWSDL uri="https://localhost:9446/services/Codelists?wsdl"/>
<policy key="conf:/repository/axis2/service-groups/Codelists/services/Codelists/policies/UTOverTransport"/>
<enableSec/>
</proxy>
但是当我使用“TryIt”功能时使用此配置，我会收到授权错误或者：
