Key: AXIS2-4662
URL: https://issues.apache.org/jira/browse/AXIS2-4662
Project: Axis2
Issue Type: Improvement
Components: kernel
Affects Versions: 1.5.1
Reporter: Stephan van Hugten
Fix For: 1.5.1
I wanted to create an application that has tight integration between Axis2
webservices and Spring. There is already a solution presented at the Axis2
website, http://ws.apache.org/axis2/1_5_1/spring.html, but I found that
solution very cumbersome in my opinion and doesn't support the JSR 181
annotations.
With my proposed approach it is possible to fully integrate the Axis2 run-time
with a spring container, whether it is stand-alone or in a web server such as
Tomcat. This solution also supports both the JSR 181 annotated classes and the
regular AAR-files.
To fully integrate Axis2 with Spring I have overridden the SimpleAxis2Server
class used by the standard stand-alone run-time. A full listing of this class
is included in my example application.
The important stuff is in line 21 up to 36. First it determines the absolute
path of the repository and config location parameters. Then it passes those to
the AxisRunner constructor (lines 10 to 13) and starts the server. After it
successfully starts the Axis2 server it returns the bean to the Spring
Container.
After the creation of the bean it will invoke setDeployedWebservices (lines 46
to 51) which will cycle through the passed webservice classes and deploy them
at the created run-time. That's it! No additional configuration or packaging is
needed. If the Spring container starts up, so does the Axis2 run-time and the
webservices get deployed.
The needed configuration in order to integrate Axis2 is quite simple. Below is
a complete listing of my applicationContext.xml (Spring 2.5.6):
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="namespace stuff">
<bean name="axisServer" class="com.example.poc.server.AxisRunner"
factory-method="create" scope="singleton">
<constructor-arg value="repository" />
<constructor-arg value="config/axis2.xml" />
<property name="deployedWebservices">
<props>
<prop key="WeatherSpringService">
com.example.poc.webservice.WeatherSpringService
</prop>
</props>
</property>
</bean>
</beans>
With a little bit more effort I think it's also possible to integrate this
solution with the Spring component scan, making it possible to annotate the
webservice classes and the run-time with @component.
