Class SimpleServletPostProcessor
- All Implemented Interfaces:
org.springframework.beans.factory.Aware
,org.springframework.beans.factory.config.BeanPostProcessor
,org.springframework.beans.factory.config.DestructionAwareBeanPostProcessor
,org.springframework.web.context.ServletConfigAware
,org.springframework.web.context.ServletContextAware
BeanPostProcessor
that applies initialization and destruction callbacks to beans that
implement the Servlet
interface.
After initialization of the bean instance, the Servlet init
method will be called with a ServletConfig that contains the bean name
of the Servlet and the ServletContext that it is running in.
Before destruction of the bean instance, the Servlet destroy
will be called.
Note that this post-processor does not support Servlet initialization parameters. Bean instances that implement the Servlet interface are supposed to be configured like any other Spring bean, that is, through constructor arguments or bean properties.
For reuse of a Servlet implementation in a plain Servlet container
and as a bean in a Spring context, consider deriving from Spring's
HttpServletBean
base class that
applies Servlet initialization parameters as bean properties, supporting
both the standard Servlet and the Spring bean initialization style.
Alternatively, consider wrapping a Servlet with Spring's
ServletWrappingController
.
This is particularly appropriate for existing Servlet classes,
allowing to specify Servlet initialization parameters etc.
