What Chris has said is right.
But what Jose Luis asked for is a inject mechanism likes
ParameterAware which takes all the request params through one Map, but
not through several property.
So I think the simpler (also more Quick And Dirty) way is:
(1)Create a interface, likes:
public interface HeaderAware {
/**
* Sets the map of request headers in the implementing class.
*
* @param headers
* a Map of headers (name/value Strings).
*/
public void setHeaders(final Map<String, String[]> headers);
}
(2)implement this interface in your action class (or the common super
class of all of your actions)
(3)create a interceptor, which inject the headers map to your action
class likes what ServletConfigInterceptor is doing,
the code will likes:
public class RequestHeaderInterceptor extends AbstractInterceptor {
@Override
public String intercept(final ActionInvocation invocation) throws
Exception {
final Object action = invocation.getAction();
if (action instanceof HeaderAware) {
Map<String, String[]> requestHeaders =
this.getRequestHeaders(ServletActionContext.getRequest());
((HeaderAware) action).setHeaders(requestHeaders);
}
return invocation.invoke();
}
private Map<String, String[]> getRequestHeaders(
final HttpServletRequest request) {
Map<String, String[]> headers = new HashMap<String, String[]>();
// TODO: retrieve all the request headers by
// HttpServletRequest.getHeaderNames(),
HttpServletRequest.getHeaders()
// and put them into Map
return headers;
}
}
(4)add RequestHeaderInterceptor into your interceptor-stack
