Scripting Module - Examples - Mule 4
The following Scripting module examples show you how to use binding variables and how to access the registry.
Use Binding Variables Example
The following Scripting Module XML example shows how to:
-
Use a flow variable in the scripting code, such as
vars.increment -
Use scripting parameters by referencing them, such as
initialValue -
Log some information by using the
logvariable, such aslog.info("….") -
Use the
resultvariable to set the result of the execution -
Define the payload in
vars.increment + Number(payload) + initialValue
<set-variable variableName="increment" value="#[22]" />
<scripting:execute engine="ECMAScript">
<scripting:code>
log.info("Incrementing payload by " + (vars.increment + initialValue))
result = vars.increment + Number(payload) + initialValue
</scripting:code>
<scripting:parameters><![CDATA[#[{ initialValue: 10 }]]]></scripting:parameters>
</scripting:execute>Access the Registry Example
The following Scripting Module XML example shows how to:
-
Access the registry
-
Stop or start a flow
<scripting:execute engine="Groovy">
<scripting:code ><![CDATA[flow = registry.lookupByName("test-flow").get();
if (flow.isStarted())
flow.stop()
else
flow.start()]]>
</scripting:code>
</scripting:execute>
