| MyPersonalizerRequestProcessor | | public class MyPersonalizerRequestProcessor extends RequestProcessor (Code) | | This is a sublcass of Jakarta Struts' RequestProcessor, which
function is to manage controller requests in an MVC architecture.
The functionality it adds is processing filters: before each request
is processed (by super.processActionPerform), MyPersonalizerRequestProcessor
applies a chain of filters to the request, so that functionality like
session managing, cookie checking or requiring authentication for
actions can be enabled through filters.
The chain of filters that will be applied is defined with configuration
parameters, and it is read when the class MyPersonalizerRequestProcessor
is first loaded. For each filter, a unique instance of its class is
created and then pushed into the chain.
For each filter, the following configuration parameters are needed:
- Its class
- Optionally, the filter's configuration parameters
The order in which filters are defined in configuration parameters
determines its execution order when a request arrives.
This configuration data is taken from a
MyPersonalizerRequestProcessorConfig object created with the data from
configuration files.
