如何在Liferay中为Portlet映射过滤器？

Question

I just created one filter inside my portlet and I want to execute it when one of the page inside my portlet is getting loaded.

How can I map the filter for this requirement?

If you'd let us know what you want to achieve, someone might come up with a better way to implement this. For now, you should bind your filter to /* and check for the expected URL yourself. Reasons: Liferay can show your page as /web/guest/my-page-name in the default language, /en/web/guest/my-page-name as an explicitly requested english page, /my-page-name when virtual hosting is enabled and the hosts match.

For some (maybe performance?) reasons servlet filter URLs must not start with wildcards, but can end in them. Thus you'll have to work with this limitations if a servlet filter is your tool of choice. As I said above, if we knew what you try to achieve, we might point out a better solution.
