WSO2治理注册表未将服务发布到WSO2 API管理器中

Question

On "publish" button click (current service state "Production") I am getting below error in WSO2 Governance Registry console.

Failed to invoke aspect: An exception occurred while executing handler chain. APIManager endpoint URL or credentials are not definedAPI Publish might fail**

Below is my WSO2 Gov reg configuration as described in this link .

<state id="Production">
                <datamodel>
                    <data name="transitionExecution">
                        <execution forEvent="Demote" class="org.wso2.carbon.governance.registry.extensions.executors.DemoteActionExecutor">

Please suggest.

Answer 1

This link in WSO2 docs affirms that you have to modify /repository/resources/lifecycles/configurations.xml, but I think this is incorrect . Infact in Greg 4.6.0 this file is no more used. Another version of it is stored in a small db and you MUST make changes from GReg administration console just go to Extensions->Configure->Lifecycles and edit ServiceLifeCycle with your APIM parameters.

Answer 2

Use G-Reg version 5.0.0 and above and API manager 1.9.0 or 1.9.1. Refer the following documentation

https://docs.wso2.com/display/AM190/Integrating+with+WSO2+Governance+Registry

对于apim端点，仅使用http://localhost:9763/而不是http://localhost:9763/store.
