Class ProcessingUnitContextLoader

java.lang.Object
org.springframework.web.context.ContextLoader
org.openspaces.pu.container.jee.context.ProcessingUnitContextLoader
public class ProcessingUnitContextLoader extends org.springframework.web.context.ContextLoader
Same as Spring ContextLoader. Different in two aspects:

The first, it automatillcay loads the binded META-INF/spring/pu.xml (binded into the servlet context) as the parent application context. See loadParentContext(jakarta.servlet.ServletContext).

Second, it overrides the creation of WebApplicationContext and automatically adds ClusterInfo and BeanLevelProperties handling. It also delegates the objects to the web context level Spring application context.
