Round-tripping support in Spring Roofor web controllers and views

In Roo-generated applications, you can change JPA entities and let Roo take care of making necessary changes to the controllers and views. In this recipe, we look at an example scenario, which demonstrates how changes to a JPA entity are propagated to corresponding controllers and views.

Getting ready

Delete the contents of the ch04-recipe sub-directory inside the C:\roo-cookbook directory.

Copy the ch04_web-app.roo script into the ch04-recipe directory.

Execute the ch04_web-app.roo script that creates the flight-app Roo project, sets up Hibernate as the persistence provider, configures MySQL as the database for the application, creates Flight and FlightDescription JPA entities, and defines a many-to-one relationship between the Flight and FlightDescription entities. If you are using a different database than MySQL or your connection settings are different than what is specified in the script, then modify the script accordingly...
