How can I convert a spring data Sort to a querydsl OrderSpecifier?

Question

This is basically the opposite of this: How to do a paged QueryDSL query with Spring JPA?

This is for a custom query for which i can\'t use any of the findAll() methods.

You can do somethings like this: But make sure to trim the o.getProperty() so you only pass the property and not "alias."+property

    if (pageable != null) {
                query.offset(pageable.getOffset());
                query.limit(pageable.getPageSize());
                for (Sort.Order o : pageable.getSort()) {
                    PathBuilder orderByExpression = new PathBuilder(Object.class, "object");

                    query.orderBy(new OrderSpecifier(o.isAscending() ? com.mysema.query.types.Order.ASC
                            : com.mysema.query.types.Order.DESC, orderByExpression.get(o.getProperty())));
                }
            }
