This wizard generates a set of entity classes from an existing database connection or schema. The IDE generates an entity class for each related table with persistent fields. The wizard takes you through the steps of choosing the database connection or schema, and then selecting the tables in the database that will be used to generate the entity classes.
You open the wizard by right-clicking a project node or subnode and choosing New > Other, selecting the Persistence category and then selecting Entity Classes from Database.
In this page of the wizard you can set the following options for configuring generated annotation elements:
When this option is deselected, the field name is generated according to the name of the table that contains the foreign key. In the example above, the generated field name will be microMarket.
When you click Finish, the IDE creates entity classes for each of the tables you specified in the wizard.
