Example 1 with Identifier

use of org.springframework.roo.addon.jpa.addon.identifier.Identifier in project spring-roo by spring-projects.

the class DbreDatabaseListenerImpl method getIdentifiers.

private List<Identifier> getIdentifiers(final Table table, final boolean usePrimaryKeys) {
    final List<Identifier> result = new ArrayList<Identifier>();

        result.add(new Identifier(fieldName, fieldType, columnName, column.getColumnSize(), column.getScale(), columnDefinition));
    }
    return result;
}

Example 2 with Identifier

use of org.springframework.roo.addon.jpa.addon.identifier.Identifier in project spring-roo by spring-projects.

the class DbreDatabaseListenerImpl method manageIdentifier.

private void manageIdentifier(final JavaType javaType, final AnnotationMetadataBuilder jpaAnnotationBuilder, final Set<JavaSymbolName> attributesToDeleteIfPresent, final Table table) {

        // We don't need a PK class
        final List<Identifier> identifiers = getIdentifiersFromPrimaryKeys(table);

            createIdentifierClass(identifierType);
        }
        jpaAnnotationBuilder.addClassAttribute(IDENTIFIER_TYPE, identifierType);
        // We need a PK class, so we tell the IdentifierMetadataProvider via
        // IdentifierService the various column names, field types and field
        // names to use
        // For tables with no primary keys, create a composite key using all
        // the table's columns
        final List<Identifier> identifiers = pkCount == 0 ? getIdentifiersFromColumns(table) : getIdentifiersFromPrimaryKeys(table);
        identifierResults.put(identifierType, identifiers);
    }
}

Example 3 with Identifier

use of org.springframework.roo.addon.jpa.addon.identifier.Identifier in project spring-roo by spring-projects.

    // ANY identifier-related attributes on @RooJpaEntity....
