Example 1 with PrimaryKey

use of core.framework.db.PrimaryKey in project core-ng-project by neowu.

the class DatabaseClassValidator method visitField.

@Override
public void visitField(Field field, String parentPath) {
    Class<?> fieldClass = field.getType();
    Column column = field.getDeclaredAnnotation(Column.class);
    if (column == null)
        throw Exceptions.error("db entity field must have @Column, field={}", Fields.path(field));
    if (columns.contains(column.name())) {
        throw Exceptions.error("found duplicate column, field={}, column={}", Fields.path(field), column.name());
    } else {
        columns.add(column.name());
    }
    if (fieldClass.isEnum()) {
        validateEnumClass(fieldClass, field);
    }
    PrimaryKey primaryKey = field.getDeclaredAnnotation(PrimaryKey.class);
    if (primaryKey != null) {
        foundPrimaryKey = true;
        validatePrimaryKey(primaryKey, fieldClass, field);
    }
}

Example 2 with PrimaryKey
