Class CompositeActionMapper
java.lang.Object
 com.opensymphony.webwork.dispatcher.mapper.CompositeActionMapper
- All Implemented Interfaces:
- ActionMapper
public class CompositeActionMapper - extends Object
- implements ActionMapper
This is an ActionMapper that could take in ActionMappers and consult each ActionMapper
in the order they are given where ActionMapper with higher order will take precedence.
The pre-defined ActionMappers could be configured in 2 ways :-
Through webwork.properties
CompositeActionMapper does this by reading in the pre-configured ActionMappers
through webwork.properties file eg. with
webwork.mapper.class=com.opensymphony.webwork.dispatcher.mapper.CompositeActionMapper
webwork.compositeActionMapper.1=com.opensymphony.webwork.dispatcher.mapper.RestfulActionMapper
webwork.compositeActionMapper.2=com.opensymphony.webwork.dispatcher.mapper.DefaultActionMapper
We would have configured a CompositeActionMapper, with 2 pre-configured ActionMappers, namely
- com.opensymphony.webwork.dispatcher.mapper.RestfulActionMapper
- com.opensymphony.webwork.dispatcher.mapper.DefaultActionMapper
where RestfulActionMapper will be consulted first before DefaultActionMapper as it has a higher order.
ActionMapper with a lower order will be consulted first.
Through constructor (normally for unit testing)
CompositeActionMapper does this with the pre-configured ActionMappers
passed in as an array. The order of the ActionMappers is important as they will be consulted
in order.

CompositeActionMapper
public CompositeActionMapper()
- Creates an instance of
CompositeActionMapper, reading in the pre-configured ActionMappers
through webwork.properties file eg. with
webwork.mapper.class=com.opensymphony.webwork.dispatcher.mapper.CompositeActionMapper
webwork.compositeActionMapper.1=com.opensymphony.webwork.dispatcher.mapper.RestfulActionMapper
webwork.compositeActionMapper.2=com.opensymphony.webwork.dispatcher.mapper.DefaultActionMapper
We would have configured a CompositeActionMapper, with 2 pre-configured ActionMappers, namely
- com.opensymphony.webwork.dispatcher.mapper.RestfulActionMapper
- com.opensymphony.webwork.dispatcher.mapper.DefaultActionMapper
where RestfulActionMapper will be consulted first before DefaultActionMapper as it has a higher order.
ActionMapper with a lower order will be consulted first.
CompositeActionMapper
public CompositeActionMapper(ActionMapper[] actionMappers)

CompositeActionMapper with the pre-configured ActionMappers
passed in as an array. The order of the ActionMappers is important as they will be consulted
in order.

request - HttpServletRequest
- Returns:
- ActionMapping
getUriFromActionMapping
public String getUriFromActionMapping(ActionMapping mapping)
