Objective: Demonstrate how to initialize and use a SpringBean as a mediator.

In your Synapse configuration file, add the Spring bean as shown below:

<definitions xmlns=""

    <registry provider="org.apache.synapse.registry.url.SimpleURLRegistry">
        <parameter name="root">file:repository/conf/sample/resources/</parameter>
        <parameter name="cachableDuration">15000</parameter>

    <sequence name="main">
        <!--Setting the Spring Mediator and its Spring Beans xml file location -->
        <!--Note that springtest is the bean id used in springCustomLogger.xml -->
        <spring bean="springtest" key="spring/springCustomLogger.xml"/>


In the springCustomLogger.xml file, define the Spring bean:

<?xml version="1.0" encoding="UTF-8"?>


   <bean id="springtest" class="samples.mediators.extensions.SpringCustomLogger" singleton="false">
	   <property name="userName"><value>"Synapse User"</value></property>
	   <property name="email"><value>"[email protected]"</value></property>



  • Enable logging for the samples.mediators package by adding the following line to the <ESB_HOME>/repository/conf/ file:
  • Deploy the SimpleStockQuoteService in the sample Axis2 server and start it on port 9000.
  • Start the ESB with sample configuration 470 as follows: wso2esb-samples -sn 470

In this sample, the Spring Bean SpringCustomLogger gets initialized using the springCustomLogger.xml file and then logs the message ID. Invoke the client as follows.

ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/

If you have successfully enabled logging for the samples.mediators package you will see an output similar to the following on the console:
