public class SpringServlet
A servlet or filter for deploying root resource classes with Spring integration.
This class extends ServletContainer
and initiates the
WebApplication
with a Spring-based IoCComponentProviderFactory
,
SpringComponentProviderFactory
, such that instances of resource and
provider classes declared and managed by Spring can be obtained.
Classes of Spring beans declared using XML-based configuration or auto-wire-based confguration will be automatically registered if such classes are root resource classes or provider classes. It is not necessary to provide initialization parameters for declaring classes in the web.xml unless a mixture of Spring-managed and Jersey-managed classes is required.
The servlet supports configuration of child applicationContexts,
see CONTEXT_CONFIG_LOCATION
.

protected ResourceConfig getDefaultResourceConfig(Map<String,Object> props, WebConfig webConfig) throws javax.servlet.ServletException
ServletContainer
This implementaton returns an instance of WebAppResourceConfig
that scans in files and directories as declared by the
ClasspathResourceConfig.PROPERTY_CLASSPATH
if present, otherwise
in the "WEB-INF/lib" and "WEB-INF/classes" directories.
An inheriting class may override this method to supply a different default resource configuraton implementaton.

.
This method will be called once at initiation and for each reload of the Web application.
An inheriting class may override this method to initiate the Web application with different parameters.

If the initialization parameter CONTEXT_CONFIG_LOCATION
is present then this method will invoke getChildContext(java.lang.String)
otherwise this method will invoke getDefaultContext()
.
protected org.springframework.context.ConfigurableApplicationContext getDefaultContext()
The default application context will be looked up from the servlet
context using WebApplicationContextUtils.getRequiredWebApplicationContext(javax.servlet.ServletContext)
.
protected org.springframework.context.ConfigurableApplicationContext getChildContext(String contextConfigLocation)
The child application context is created as a child of the default
application context obtained from getDefaultContext()
.
contextConfigLocation
- the location of the child application
context.
