Today, I opened two liferay-portlet environments on the E drive. They were all downloaded and bound. A bundles (with tomcat in it) + plugins-sdk (with portlet-related configurations ). Every time there is a ready-made one, the Manager will give it to us and we can use it directly. Today we don't know why we can't. Once we deploy A portlet, we will say build. cannot find D: \ develop \ bundles \ tomcat-6.0.18 \ lib in xml. I don't know. I used to be ab

IntroducedLiferay provides several ways to define complex queries that are used to retrieve data from a database.Typically, in each service entity, you can easily meet basic data query operations by defining some ' finder ' methods.However, there are times when we may encounter some of the following finder queries that are not sufficient: Overly complex queries, such as sub-queries Some aggregation operations need to be implemented, such as Min, Max, AVG, etc. Want a composite o
