java file upload - Access Spring beans from a servlet in JBoss
Your servlet can use WebApplicationContextUtils to get the application context, but then your servlet code will have a direct dependency on the Spring Framework.
Another solution is configure the application context to export the Spring bean to the servlet context as an attribute:
<bean class="org.springframework.web.context.support.ServletContextAttributeExporter"> <property name="attributes"> <map> <entry key="jobbie" value-ref="springifiedJobbie"/> </map> </property> </bean>
Your servlet can retrieve the bean from the servlet context using
SpringifiedJobbie jobbie = (SpringifiedJobbie) getServletContext().getAttribute("jobbie");
I want to write a simple servlet in JBoss which will call a method on a Spring bean. The purpose is to allow a user to kick off an internal job by hitting a URL.
What is the easiest way to get hold of a reference to my Spring bean in the servlet?
JBoss web services allow you to inject a WebServiceContext into your service class using an @Resource annotation. Is there anything comparable that works in plain servlets? A web service to solve this particular problem would be using a sledgehammer to crush a nut.
