`Spring Data Criteria` extends Spring Data JDBC & R2DBC & JPA to support dynamic sql

Spring Data Criteria extends Spring Data JDBC & Spring Data R2DBC & Spring Data JPA to support dynamic sql.

to see DATAJDBC-319, DATAJPA-2724.

The usage is as follows:

public interface UserDao extends ListCrudRepository<User, Long>, CriteriaExecutor<User> {
    default Page<User> searchByQuery(UserQuery query, Pageable pageable) {
        return findAll(Criteria.from(eq(User_.province, query.province))
                        .and(eq(User_.city, query.city))
                        .and(like(User_.area, query.area))
                        .and(like(User_.name, query.nick))
                        .and(between(User_.created, query.createFrom, query.createTo))
                , pageable);
    }
}

It will dynamically generate sql based on whether the query field is empty.
