Large portlet war takes up memory causing performance issues?

由 旧时模样 提交于 2019-12-07 18:55:01
问题 I have heard a few people say that deploying a portlet war file (or perhaps any war) that includes a lot of large jars can cause performace issues because all those jars get loaded into memory. If you have several wars, all of which include a ton of large jar files, your system will get bogged down. I'm trying to get my head around why this is true - and I haven't found anything that explains it in a way that I get it. Maybe I'm searching for the wrong terms which is why I'm not finding much

Multiple Ajax calls liferay portlets

由 自古美人都是妖i 提交于 2019-12-07 06:19:51
问题 I am having liferay portlet and I need to heavily depend upon the AJAX calls. So I need to make multiple calls to serveResource method. One way to do the same is that I can pass a parameter with the URL and then differentiate the request according to that parameter. But in my case I have to call serveResource so many times due to which the method will be difficult to maintain. Is there any framework to do so? Using which the code becomes maintainable. 回答1: Use Spring MVC framework and call
