jmigrations

Full Java Migrations Framework - inspired on Rails Migration

#Features planned

• 100% Java DSL
• Modularized
  • API
  • DSL
  • CORE
  • Standalone
  • Maven
  • Ant
  • Gradle
• Extensible
• DRY - use all Java tools and frameworks that already exists
• Can be used standalone - non Java projects can takes advantage of this

Example

public class CreateUserTable_21082012_1117_jrdalpra implements Migration {		

    @Override
    public DatabaseCommand[] up() {
        return new DatabaseCommand[] {
                createTable("user").columns(column("id").type(long_()).withOptions(notNull(), primaryKey()),
                                            column("login").type(string()).withOptions(notNull(), length(100)),
                                            column("passwd").type(string()).withOptions(notNull()))
        };
    }

    @Override
    public DatabaseCommand[] down() {
        return new DatabaseCommand[] {
                dropTable("user")
        };
    }
}

Or using lombok extension methods

@ExtensionMethod({ Extensions.Commons.class, Extensions.Options_.class, Extensions.DropTable_.class })
private static class TesteMigrationWithExtensionMethods implements Migration {

    @Override
    public DatabaseCommand[] up() {
        return new DatabaseCommand[] {
                createTable("user").columns("id".as(long_()).notNull(),
                                            "login".as(string()).notNull().length(100),
                                            "passwd".as(string()).notNull())
        };
    }

    @Override
    public DatabaseCommand[] down() {
        return new DatabaseCommand[] {
                dropTable("user").ifExists().cascade()
        };
    }
}
