Class GenericFilterBean

Direct Known Subclasses:

OncePerRequestFilter

public abstract class GenericFilterBean

implements Filter

Simple base implementation of javax.servlet.Filter that treats its config parameters as bean properties. A very handy superclass for any type of filter. Type conversion is automatic. It is also possible for subclasses to specify required properties.

This filter leaves actual filtering to subclasses.

public void destroy()

Subclasses may override this to perform custom filter shutdown. This default implementation does nothing.

public final void init(FilterConfig filterConfig)
                 throws ServletException

Map config parameters onto bean properties of this filter, and invoke subclass initialization.

Throws:

ServletException - if bean properties are invalid (or required properties are missing), or if subclass initialization fails.
