ServiceBuilder not creating FinderImpl class?

Question

I create some services using Liferay 7 . But FinderImpl and FinderUtil classes are not created after building services.The steps I followed are as follows:

1. Created a service builder project.
2. Created finder columns.
3. Built and deployed the *-api and *-service...where * is the project/service name.
4. Refresh the project using gradle ->Refresh Gradle Project.
5. Dragged and dropped the *-service and *-api onto the running server.

Result: it creates the table but *FinderImpl and *FinderUtil classes are not there in the project.

Answer 1

You have to create your *FinderImpl class and rebuild service because Finder classes are not created by default. According to the Liferay documentation:

The first step is to create a *FinderImpl class in the service persistence package. For the Guestbook application, for example, you could create a EntryFinderImpl class in the com.liferay.docs.guestbook.service.persistence.impl package. Your class should extend BasePersistenceImpl<Entry>.

Run Service Builder to generate the *Finder interface and the *Util class for the finder. Service Builder generates the *Finder interface and the *FinderUtil utility class based on the *FinderImpl class. Modify your *FinderImpl class to have it implement the *Finder interface you just generated:
