Note that WSO2 EI is shipped with the following changes to what is mentioned in this documentation:

  • <PRODUCT_HOME>/repository/samples/ directory that includes all Integration profile samples is changed to <EI_HOME>/samples/service-bus/.
  • <PRODUCT_HOME>/repository/samples/resources/ directory that includes all artifacts related to the Integration profile samples is changed to <EI_HOME>/samples/service-bus/resources/.

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:spring bean="springtest" key="spring/springCustomLogger.xml" xmlns:spring=""/>


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



   <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 <EI_HOME>/conf/ file:
  • Create the above configuration and deploy it in the ESB profile.
  • In this sample, the Spring Bean SpringCustomLogger gets initialized using the springCustomLogger.xml file and then logs the message ID.

Sending the request (example):

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:
