Spring IOC container do the magic for you:

class ListOperationsEditor extends PropertyEditorSupport {
    ListOperationsEditor() {
    }

    public void setValue(Object value) {
        if(value instanceof RedisOperations) {
            super.setValue(((RedisOperations)value).opsForList());
        } else {
            throw new IllegalArgumentException("Editor supports only conversion of type " + RedisOperations.class);
        }
    }
}
