入站端点的WSO2 ESB动态配置

Question

I configured an inbound endpoint, but I want to manage java.naming.provider.url value in a conf.xml file that under config directory in WSO2.

In each environment I have a conf.xml file which includes the URL values for that environment like:

<environment>
    <JNPU>test</JNPU>
</environment>
<test>
    <JNPU>failover:tcp://localhost:61616</JNPU>
</test>

I just want first read this environment value of the JNPU which is test in this example. Then, I want to change the java.naming.provider.url value in inbound endpoint with this value.

In a sequence, I can read the values with using these properties:

<property name="confFile" expression="get-property('registry','conf:endpoints/conf.xml')" scope="default" type="OM" xmlns:ns="http://org.apache.synapse/xsd"/>
<property name="JNPUEnvValue" expression="evaluate(fn:concat('$confFile//environment//','JNPU'))" scope="default" type="STRING" xmlns:ns="http://org.apache.synapse/xsd"/>
<property name="JNPUValue" expression="evaluate(fn:concat('$ctx:epConfiguration','//',get-property('JNPUEnvValue'),'//','JNPU'))" scope="default" type="STRING" xmlns:ns="http://org.apache.synapse/xsd"/>

I used them as parameters in inbound endpoint but I could not get the value of java.naming.provider.url in conf.xml file.

Thanks for any idea.

We can dynamically configure inbound endpoint parameters, if we save only the respective parameter value as the content of the file saved in registry. For example, in your case, the value "failover:tcp://localhost:61616" should be saved in the file. You can keep separate files for each parameter in a registry location. And, you need to only change file content for each environment.

Please refer the section Specifying inbound endpoint parameters as registry values at https://docs.wso2.com/display/EI650/WSO2+EI+Inbound+Endpoints .

如果您可以将URL保留在注册表中，则可以从注册表中使用它，如下所示。

<parameter name="java.naming.provider.url" key="gov:/Path/javaNamingProviderURL"/>
