Adding dynamic finder methods to an entity

The finder list command shows the candidate dynamic finder method names whose implementations Roo can automatically generate. In this recipe, we will look at how to add dynamic finder methods to a persistent entity using the finder add command. As an example, we will add the findFlightsByDestinationLikeAndOriginLike method to a Flight entity.

Getting ready

Refer to the Viewing candidate dynamic finder methods recipe, to create the flight-app Roo project.

Start the Roo shell from the C:\roo-cookbook\ch03-recipes directory.

How to do it...

To add dynamic finder methods, follow the given steps:

1. Set the focus of subsequent commands on the Flight entity using a focus command:

   roo> focus --class ~.domain.Flight
   

2. Add the findFlightsByDestinationLikeAndOriginLike dynamic finder method to the Flight entity using the finder add command:

   .. roo> finder add findFlightsByDestinationLikeAndOriginLike
